APPLICATION BULLETIN NO. 1010 APPLICATION / INSTALLATION DATA SHEET CHLORINATION OF COOLING WATER GENERAL In any process where water is used as a coolant, the water, particularly at elevated temperatures breeds bacteria and propagates the growth of slime and algae. The transfer of heat from the process to the cooling water often occurs in either a (1) condenser, which consists of tubes through which the process flows and is surrounded by cooling water or (2) in a cooling tower, which allows water to cascade over baffles, exposing the cooling water to air, thus cooling the water by evaporation. To keep the heat transfer process operating at maximum efficiency, the heat exchange surfaces must be free of slime and algae. Otherwise, the efficiency of the cooling facility will be severely impaired. THE NEED FOR GAS CHLORINATION Gas chlorination is the preferred method for controlling slime and algae buildup in cooling water systems. In addition, gas chlorination is the preferred method of controlling microbiological influenced corrosion (MIC), bio fouling, and fouled heat exchange surfaces. If the water quality is maintained in reasonably good condition with a low chlorine demand to begin with, chlorine is always the most economical form of treatment. The chlorine requirement in an individual system is governed by many factors, such as the quality of the makeup water, water temperature, air-to-water ratio, chlorine demand of the water, etc. GAS CHLORINE APPLICATION The manner of chlorine feed, whether continuous or intermittent, depends on the system. For any system, it is necessary to: 1. Apply sufficient chlorine to obtain the necessary residual. 2. Maintain this necessary residual for the required contact time. Generally, if the chlorination system is to operate continuously, 1 - 3 PPM dosage is commonly reported. If the chlorination system will be used intermittently (shock treatment), dosages of 3 - 8 PPM have been reported. If product contamination of the water is a problem, as in a gasoline refinery, the dosage requirement may need to be increased accordingly. The length of the chlorination cycle should be at least long enough to maintain the desired chlorine residual for one complete turnover of water. Many operators add enough chlorine to maintain a 0.5 - 1.0 PPM free chlorine residual at the tail end of the condensers, or going to the top of the towers. For some cooling towers, two chlorination cycles per day is sufficient. Other towers may require additional cycles or continuous treatment. The typical installation drawings shown on the other side of this sheet are intended as a guide only. The drawings show three possible chlorination application points to consider - intake water, circulating water, and service water. Keep in mind the following: 1. All cooling water applications require control of bacteria, slime, algae, MIC, bio-fouling, and fouled heat exchange surfaces. 2. Fresh water cooling circuits can take advantage of short contact times, and the point of application can be close to the condenser water tubes. 3. Many operators have stated that a free chlorine residual of 0.5 - 1.0 PPM at the discharge of the condensers has been sufficient to control all slime growths. 4. Chlorination ahead of the cooling water intake screens can help to control mollusks, barnacles, sponges, etc. chlorinators incorporated 1044 S.E. Dixie Cutoff Road Stuart, Florida 34994-3436 U.S.A.

No. 205-2 BULLETIN 901 REGAL™ GAS CHLORINATORS / SULPHONATORS / AMMONIATORS Safe/Reliable/Economical Safety is designed and built into the REGAL. The REGAL gas chlorinator mounts directly onto the cylinder, which is a major safety factor. Also, the design and structure of the REGAL mounting yoke is an additional safety feature. The yoke is built with the heaviest slide bars and tightening bolt in the industry, to ensure proper alignment and sealing of the lead gasket inlet connection. Safe A built-in tightening handle provides just enough leverage to tighten the yoke and seal the gasket. It will bend before allowing you to exert enough pressure to accidentally bend the yoke. This prevents the misalignment of the chlorinator's inlet adapter and the cylinder's valve, or squeezing the gasket out of the connection. Both of these can cause gas leaks, and both could happen with competitive units that require a separate wrench. An innovative, high strength fluoropolymer coating, bonded to the yoke by an electrofusion process, gives the REGAL yoke extremely high resistance to corrosion from either chlorine, sulfur dioxide or ammonia. REGAL ALL-VACUUM GAS CHLORINATION SYSTEM CHLORINATOR CLAMPS DIRECTLY ON CYLINDER VALVE VACUUM LINE IF BREAK OCCURS, CHLORINE STOPS DIFFUSER GAS CHLORINE WATER SUPPLY Safety starts right at the cylinder valve, with the REGAL heavy-duty vise-type mounting yoke. EJECTOR Built-in tightening handle 2 REGAL safety extends throughout the entire all-vacuum system. Chlorine is never under pressure in the REGAL system. A vacuum – created by water being forced under pressure through the ejector nozzle – pulls on an extremely tough and resilient diaphragm which pushes open a spring-loaded inlet safety shut-off valve. The vacuum draws the gas from the cylinder, through the chlorinator, then through highstrength vacuum tubing into the ejector. There it mixes with the water that is rushing through the ejector, is carried to the diffuser, which then passes it into the water being treated. The ALL VACUUM REGAL SYSTEMS virtually eliminate the problems associated with Old Pressure Type Manifold Systems. The safety and reliability of REGAL systems has been proven by years of customer usage worldwide. Every surface the gas touches, from the time it leaves the cylinder until it enters the water, consists of the most advanced, corrosion-resistant materials available. And there are no supply pressure lines, valves or fittings to break or corrode. But most important: should anything happen to cause a break in any part of the system, gas does not leak out. Air leaks in, and the vacuum is lost. With no vacuum to pull it open, the powerful spring on the inlet safety shut-off valve snaps the valve shut, stopping the gas supply immediately and automatically. An adjustable feed rate valve and feed rate indicator are built into the REGAL, to allow the flow of gas to be manually adjusted and observed.

Simplicity is one key to reliability – and the REGAL design is simpler and more efficient than any other comparable unit. It has only 68 parts – up to 60% fewer than competitive units. The design is so simple and logical that very little time is needed for learning how to service it. Only a screwdriver and pliers are needed for servicing. Another key to reliability is corrosion resistance, and every one of the REGAL's 68 parts is made of materials best suited to handle the gas form of CL2, SO2, or NH3. (Please note: REGAL gas chlorinators, sulphonators and ammoniators are all made of different materials and must be used with the gas for which each is intended). These feeders are designed for gas use only. The liquid form of these chemicals WILL cause damage to system components. Therefore, if liquid chemical does enter the system components, contact the factory immediately. Reliable Every REGAL is completely hand-assembled by highly skilled technicians who are responsible for the unit being in perfect condition before it leaves his or her hands.This involves careful visual inspection at every step of the process and bench testing of the completed unit. When the assembling technician is completely satisfied with the unit, it is sent to the REGAL testing room.There it receives a series of stringent tests to a) make sure it has no gas leaks, b) check its vacuum integrity, and c) measure its operating performance. All these tests are performed against high-efficiency performance curves, unless the customer has supplied us with data that enable us to test the system against actual operating conditions in the intended application. THE REGAL INSIDE STORY Built-in tightening handle 5/8" (16mm) yoke slide bar Corrosion resistant bolts REGAL Gas Chlorinators/ Gas Sulphonators are easy to maintain • Efficient, simple design 5/8" (16mm) diameter yoke-mounting bolt High-efficiency filter is re-usable Inlet adapter is resistant against corrosion Corrosion-proof coating on all major yoke parts Heavy-duty bodies and O-ring sealing eliminate warping and cracking due to overtightening All O-rings are impervious to wet and dry chlorine Inlet capsule can be easily removed for cleaning Self-centering diaphragm assembly eliminates need for special tools Inlet valve/vent plugs are corrosion proof “Seatless” rate valve eliminates valve plug damage and gouged seats; one valve handles all capacities up to 100 PPD • Only 68 parts • Quality materials that stand up to wet and dry chlorine attack • Only screwdriver and pliers needed for servicing • Capacities up to 2000 lbs/day 4 Combined O-ring and diaphragm sealing of joint between front and rear housings minimizes possibility of vacuum leaks Inlet spring has limited lifetime warranty against corrosion (Chlorinator only) Simplified chlorine supply indicator eliminates possibility of false indication or mechanical hangup of complicated flags and cam mechanisms Single, heavy-weight diaphragm has limited lifetime warranty against corrosion Body bolts engage with metal nuts molded into front body...no plastic threads to strip Metering tubes calibrated in both English and metric units (ppd or g/hr) The REGAL ejector is another factor in the system's reliability and economy. The ejector performs three of the system's most vital functions: • It creates the vacuum that pulls the gas from the cylinder. Without the vacuum, the system will not operate. If the ejector isn't functioning properly, there is no vacuum. • It mixes the chlorine, sulfur dioxide or ammonia with the water. • It keeps water from entering the system. HOW THE EJECTOR PRODUCES A VACUUM Vacuum is created by water under pressure flowing through a very efficient, constant differential The REGAL ejector consists of four components, all of them made of very strong, special plastic, which enables it to withstand a back-pressure rating of 200 psig. It can be taken apart for cleaning – and put back together – in minutes, with no special tools. venturi in the nozzle. At the Our nozzle has been designed to produce the highest vacuum at the lowest pressures and water flow rates. If you need a booster pump you can use the economical centrifugal type. Because we know that our single-piece nozzle will never be misaligned and that its operating characteristics will never change, we can pre-test every one against an optimum performance curve. venturi and immediately step back venturi, there is a pressure drop as the molecules of water pass at high speed through the restricted out to a larger unrestricted area.This always forms a vacuum as long as the inlet supply pressure is high enough to overcome the total system backpressure. When the system is shut off, pressure from water flowing through the nozzle could force water up the same tube through which chlorine enters when the system is operating – if the ejector did not incorporate a one-way check valve. REGAL offers two distinctly different check valves – one for high back pressures, one for low. Both are designed and built for the highest reliability, highest performance and lowest maintenance. LOW PRESSURE EJECTOR HIGH PRESSURE EJECTOR 5 REGAL is the most economical because it lasts longer. WHY TWO CHECK VALVES? BECAUSE COMPROMISES DON'T WORK. High and low back pressures require entirely different kinds of check valves. REGAL gives you both. For high pressures, REGAL offers a single piece check valve that utilizes pressure to close it. Economical Where back pressure isn't strong enough to close the check valve we've designed a check valve with a closing spring strong enough to give a bubble-tight seal, and a diaphragm with large enough surface area to eliminate any friction loss or pressure drop across the check valve. Both check valves are made of materials totally resistant to chemical attack by both wet and dry chlorine, sulfur dioxide or ammonia. OPERATING SHUT-OFF OPTIONAL DUAL CHECK VALVE EJECTOR TO 500 PPD. The REGAL Dual Check Valve Ejector has a ball check valve as the primary check valve backed up by a spring loaded 0-ring/poppet check valve. One-Piece Ejector Valve Stops High-Pressure Wear Problems REGAL FILTER CATCHES FINER PARTICLES, SAVES MONEY, TOO. REGAL uses an innovative corrosion resistant (dual thickness) plastic filter that is suitable for chlorine or sulfur dioxide systems. It saves money because it can be cleaned and reused indefinitely. Inlet Filter Single-Purpose Low-Pressure Valve Assures Tight Low-Pressure Seal RATE VALVE WITH TAPERED OPENING ELIMINATES VALVE SEAT, FOR MORE ACCURATE SETTINGS – AND LONGER LIFE. The “seat” used in most rate valves is subject to wear, and is frequently damaged, particularly at low feed rates. By eliminating the seat, and relying instead on a tapered opening to control the flow, we have not only greatly extended the life of the rate valve, but also increased its accuracy. Rates can be set as easily and accurately at the bottom end of the metering tube as at the top, and the maximum feed rate can be changed by merely changing the flow metering tube. The same rate valve is used for all standard rates up to 100 lbs/day (2 kg/hr). “Seatless” Rate Valve 6 The diaphragm and the inlet safety shut-off spring are the two chlorinator parts most vulnerable to corrosion, but in the REGAL, they are corrosion-proof. CORROSION-RESISTANT, METALLIC INLET ADAPTER The inlet adapter is the last point at which the gas is still under pressure and therefore must be made of a material strong enough to handle the pressurized gas without being compromised.The REGAL inlet adapter is made from a special metal alloy that is virtually impervious to attack by dry, wet, or even liquid chlorine and sulfur dioxide under normal circumstances and operating conditions. CORROSION-PROOF, SUPER-STRONG DIAPHRAGM The diaphragm opens the inlet safety valve to allow the gas to flow, and maintains a steady flow of gas while the system is in operation. Any damage to the diaphragm – even a tiny crack or pinhole – would prevent it from performing these functions. And continuous exposure to the gas would cause these problems if the REGAL diaphragm were not twice as thick and three times as strong as its competition, and made of a plastic that will not corrode. CORROSION-PROOF, HEAVY DUTY INLET/SAFETY SHUTOFF VALVE SPRING Particles small enough to get through the REGAL filter do, in time, build up on the inlet safety shutoff valve, valve seat and spring. These must be cleaned periodically. In competitive units this is a tough, time consuming and costly job. In the REGAL, however, these components are housed in a capsule that can be removed with just a screwdriver and pliers, taken apart for cleaning, reassembled, and put back in place, in less than ten minutes. The heavy duty spring, one of the most critical parts in any gas chlorinator, carries a LIMITED LIFETIME WARRANTY. We have placed LIMITED LIFETIME WARRANTIES against corrosion on the diaphragm and inlet safety shut-off spring in all REGAL chlorinators and sulphonators. It needs very little servicing, and is easy to take apart for cleaning. What's true of the system as a whole, is true of every one of its parts. 7 The same quality, simplicity and ease of maintenance has been developed into ALL models of REGAL standard units, switchover systems and high capacity gas chlorinators. REGAL Wall-Mounted Chlorinators For Multi-Cylinder Chlorination When larger reserve and/or feed rate capacities are needed, REGAL offers a choice of wall manifolds interconnecting one or more cylinders or to n co n t a i n e r s to vacuum regulator(s). However,because direct cylinder mounting is one of the basic safety features of the REGAL, manifolding does reduce its inherent safety. It also adds the hazards associated with pressurized flexible connectors. Manifolding should be avoided if possible. REGAL Ton-Container Mounting Adapter TAY-200 These adapters make it possible for users with continuous feed rate requirements of 500 ppd or less to benefit from REGAL safety, reliability, and economy, and still benefit from the lower gas costs associated with ton containers. The REGAL mounts directly on the adapter, with its positive mounting yoke, and the adapter mounts directly on the ton container – eliminating the need for hazardous, pressurized, flexible connectors, and allowing great flexibility in locating the container. REGAL Series 2000 High Capacity Gas Chlorinators All the features that have made the REGAL Series 200 low to medium-capacity units the standard of the industry are embodied in the Series 2000 High Capacity Gas Chlorinators. • They mount directly to the valves of approved gas manifold assemblies. • They employ the same safe operating principle: chlorine is drawn through the regulator and metering panel by a vacuum created by water being forced under pressure through an ejector nozzle. Chlorine is never under pressure in the system. • Their simple design uses fewer parts than competitive units; all parts are designed for maximum strength, and are made of corrosion resistant or corrosion proof materials. • They do not require cabinets, therefore they save space. • They are quick and easy to service and maintain. • They can be used in multi-point applications. • Automatic switchover models are available. REGAL Series 200 Feed Rates For Chlorine REGAL Series 2000 Feed Rates For Chlorine Maximum gas feed rate capacities: 1.5, 4, 10, 25, 50, 100, 250, or 500 pounds per 24 hours (75, 200, 500, 900, 2000, 5000 gms./hr and 10kg/hr).

Pub. No. 905-4 REGAL™ MODEL 7009/7010 Bulletin 7009/7010 ™ SMARTVALVE FOR FEEDBACK (CLOSED LOOP) CONTROL SCHEMES Chlorinators’ new Model 7009 and Model 7010 SMARTVALVEs are highly sophisticated control valves for use wherever chlorine or sulfur dioxide is needed to treat varying water flow rates and/or varying water quality. These SMARTVALVEs: • Can be configured to operate in either of the following control schemes: flow proportional control, residual only control, compound loop control or feed forward dechlorination control. • Include a unique “linearization” program that assures the SMARTVALVE’s digital display reading matches the reading indicated on the gas feed system’s metering tube. • Can automatically compensate for changing system hydraulic “lag time” that occurs as the water flow rate increases and decreases. • Can operate with ORP monitors or residual analyzers. • Include an adjustable “deviation alarm” consisting of an LED and a relay that alerts operators when residual is too low or too high. • Include a residual “deadband” adjustment within which the controller will not make any corrections. This is to enhance the stability of the feedback control scheme. • Can be operated in the field four ways: fully automatic, electric/manual, and two (2) methods of manual. • Digital display and annunciator LEDs indicate: – Flow process variable in actual numbers or as a percent of flow. – Residual process variable in PPM residual or ORP value. – Valve plug position in pounds per day (PPD) of actual gas feed rate. ® SMARTVALVE – Mode of operation: automatic or manual. – Setpoint value: • Residual: 0.2 – 20.0 PPM • ORP: 1.0 – 2000 mV – Dosage value: .01 to 4.00. PATENT PENDING REGAL MODEL 7009/7010 SMARTVALVE THEORY OF OPERATION Compound Loop Control A water flow meter with a 4-20 mA signal transmitter continually measures the amount of water flowing and transmits instantaneous signals to the primary input of the REGAL Model 7009 or 7010 SMARTVALVE causing the valve to feed the correct amount of chemical to the water based on the immediate dosage setting. At the same time, a residual or ORP analyzer draws a continuous sample of the treated water at the appropriate point downstream of the chemical injection point (after suitable mixing is achieved) and sends a proportional signal to the secondary input of the REGAL Model 7009 or 7010 SMARTVALVE based on the value of the actual residual measured. The controller circuitry in the SMARTVALVE compares the measured residual to the desired residual (operator established set point) and sends a timed correction signal to the SMARTVALVE motor driver circuitry based on the results of the analysis. If the analysis shows an actual residual greater than (or less than) the desired residual, the timed correction signal opens or closes the SMARTVALVE motor driver circuitry as necessary in an attempt to keep these two values the same.

No. 507-1 Bulletin 3000 ™ REGAL SERIES 3000 GAS DETECTOR The new REGAL Chlorine or Sulfur Dioxide Gas Detectors are designed for use wherever chlorine or sulfur dioxide is stored, distributed, or where potential leakage would pose a risk for personnel and property. • Properly installed, calibrated and maintained, the REGAL Gas Detector senses the presence of free chlorine or sulfur dioxide in the environment - at levels below those mandated by OSHA throughout the working life of the sensor. • 3 - digit display and 12 LED bar graph shows the chlorine or sulfur dioxide gas concentration. • Audible and relay ‘warning’ alarm at 1 PPM for chlorine and at 2 PPM for sulfur dioxide and ‘danger’ alarm at 3 PPM for chlorine and at 5 PPM for sulfur dioxide. • Displays and transmits sensor or signal failures via an LED and a designated relay. • Maintenance-free sensor. • Capable of transmitting digital information for computerized data logging. • Bar graph LED representing the highest (10 PPM maximum for CL 2 and 20 PPM maximum for SO2) detected level stays lit until manually reset even as the gas concentration decreases. ® • No need to flush, purge or recalibrate the sensor after an exposure to chlorine or sulfur dioxide gas. • An “optional” Regal Serial to Analog Converter is available to provide a 4-20 milliamp DC output equal to gas concentration in PPM (mg/l). REGAL SERIES 3000 GAS DETECTOR THEORY OF OPERATION A regulated voltage of 24 VDC is provided over a two-wire shielded cable to the sensor unit from the detector’s main power supply. The sensor transmitter board converts the sensor cell output, which is representative of the chlorine gas concentration, to a 4-20 milliamp DC output signal for transmission to the receiver board. The receiver board converts the analog current signal to a continuous pulse train for processing by the microcontroller. When the unit is subjected to the varying concentrations of gas (up to 10 PPM for chlorine and up to 20 PPM for sulfur dioxide), the detector displays the actual concentration on the 3 digit display. The respective LED’s on the bar graph also light. As the concentration of gas increases, the appropriate bar graph LED’s blink and the audible alarm sounds when it passes the WARNING alarm point (1 PPM for chlorine and 2 PPM for sulfur dioxide) and the DANGER alarm point (3PPM for chlorine and 5 PPM for sulfur dioxide) thresholds.

SMARTVALVE PATENT PENDING CONTINUED ON OTHER SIDE REGAL SERIES 7000 SMARTVALVE Standard features include: • An isolated and powered 4-20 mA output signal provides remote indication of gas feed rate . THEORY OF OPERATION As previously mentioned, all REGAL SMARTVALVES are designed to automatically regulate the gas feed rate that is necessary to maintain the desired chemical residual. Regardless of which control scheme the SMARTVALVE is configured for, the main factors to determine this regulation are both the volume and quality of the water that is being treated. Analog output (4-20 milliamp) is transmitted to the SMARTVALVE from a water flow meter and/or a residual analyzer to signal the valve when and how much adjustment is required to maintain the proper residual.

No. 1106-1 Bulletin 216 REGAL AUTOMATIC SWITCHOVER TM GAS CHLORINATORS and SULPHONATORS STAND-BY CHLORINATION: The safest, most reliable, most economical systems to use when service must not be interrupted but cannot be monitored at all times. SAFEST BECAUSE THEY’RE REGAL™ REGAL™ Chlorinators and Sulphonators are known worldwide as the safest on the market. Here’s why: • They clamp directly onto the cylinder valve with the strongest, most corrosion-resistant yoke in the industry. • In the chlorinator or sulphonator system, the gas is never under pressure. Chlorine or sulfur dioxide is drawn from the cylinder by a vacuum created by the flow of water through the ejector. If any part of the system is damaged, the gas shuts off immediately and automatically. • The REGAL ejector nozzle (venturi) – the component that creates the vacuum which draws the gas from the cylinder – is a single, precisely manufactured piece, made of strong, corrosion-resistant plastic. • The REGAL single-piece high pressure check valve is made of a special, chlorine-and-sulfur-dioxideresistant material. The REGAL low pressure check valve uses a very strong closing spring and a largearea diaphragm, to minimize friction loss or pressure drop across the check valve area.

REGAL Switchover Chlorinators and Sulphonators have all the reliability factors that standard REGAL units are noted for: the same simple, efficient design and the same bigger, more corrosion-resistant vital parts than competitive units have. The basic difference between the standard and switchover REGALs is that the latter have built-in corrosion-proof and permanently adjusted switchover latches and reset knobs* – which like everything else bearing the REGAL name, are designed with simplicity in mind. * Other differences are: in the switchover units, the flowmeter/rate valve and the pressure relief valve are separate, wall-mounted units – as they must be, because they serve whichever chlorinator or sulphonator is operating at the moment. Also the gas supply indicator has been replaced with an indicator that shows which unit is in use and which is the stand-by. Should something happen to the operating unit, the other is available to provide continuous operation of the gas supply. Inlet Spring with Limited Lifetime Warranty Operating Diaphragm with Limited Lifetime Warranty Gas Inlet Closed Gas Inlet Opened Lead Gasket By contrast, the wall-mounted, vacuum/ differential-pressure regulators required by competitive systems are relatively complex. A failure of any component in these competitive external regulators means a total loss of disinfection – a serious matter. Each unit is complete...you can be sure to have a full supply of gas no matter what. In normal operation, one unit supplies gas until its cylinder approaches empty – at which point the other unit starts opening up, keeping the gas supply steady.

MOST ECONOMICAL BECAUSE THEY’RE REGAL™ REGAL Chlorinators and Sulphonators are the most economical for these basic reasons: 1. They are so rugged, so reliable, and so corrosionresistant that they hardly ever need servicing. 2. If they ever do need servicing or if they are seriously damaged or impurities ever get into them – you can take them completely apart and reassemble them in minutes, using only a screwdriver and a pair of pliers. And if you need a new part, we'll send it out as soon as you call us. 3. The switchover latching devices in the REGAL units are permanently adjusted, unlike the separate, external switchover units of competitive systems, which must be adjusted frequently.

Shaft direction shall be a function of phase sequence, and speed shall be a function of the pulse rate. The rotary motion of the motor shall be converted to a linear motion driving a precision machined valve plug in an orifice via a lead screw. GENERAL The REGAL Series 7009/7010 SMARTVALVES™ shall be a modular system component with built-in microprocessor controller capable of performing open loop and closed loop control schemes. The valve plug shall move linearly a maximum of 1" for all capacities through 2000 PPD based on a maximum of sixteen revolutions of the stepper motor with two hundred precise motor positioning points per revolution. The lead screw and valve plug shall move linearly a maximum of 0.0003125" per motor pulse @ 1" travel. The REGAL SMARTVALVE shall offer the user a choice of four (4) automatic control schemes; Flow Proportional Control, Residual (ONLY) Control, Compound Loop Control or Feed Forward Dechlorination Control. These control schemes are briefly defined as follows: A.Flow Proportional Control (FPC) This control scheme is needed whenever the water flow rate to be treated varies and will work well as long as the quality of the water remains constant. In this control scheme, the SMARTVALVE automatically regulates the magnitude of gas flow from a REGAL Gas Feed System in direct proportion to the varying system water flow rates. The required ratio “dosage” of chemical to the water flow is easily set by the operator to maintain the desired residual using the keypad on the SMARTVALVE enclosure. B.Residual (ONLY) Control (rES.C) This control scheme is used when the system water flow rate is non-varying but the quality (demand) of the water varies. In this control scheme, a residual or ORP analyzer takes a continuous sample of the properly mixed, treated water downstream of the chemical injection point and sends a proportional signal to the SMARTVALVE controller circuitry representative of the actual residual measured. The SMARTVALVE compares the measured residual value to the desired residual value and sends a correction signal to the SMARTVALVE’s motor driver circuitry as necessary in an attempt to keep these two values the same. C.Compound Loop Control (CLC) This control scheme is needed when both the system water flow rate and the quality of the water varies. In essence, it is a combination of Flow Proportional and Residual only Control. Flow Proportional Control takes care of volumetric water flow rate changes while Residual Control automatically compensates for changes in water quality. D.Feed Forward Dechlorination Control (FF.dC) In a Feed Forward Dechlorination Control System, a residual or ORP analyzer is used to measure the chlorine residual BEFORE the sulfur dioxide application point and based on the results of the analysis, a correction signal is generated to furnish the required dose of sulfur dioxide needed to reduce the chlorine residual analyzed. In this system, the control analyzer does not see the results of the sulfur dioxide application. GENERAL SPECIFICATIONS The REGAL SMARTVALVE shall be available in eight (8) maximum capacities: 10, 25, 50, 100, 250, 500, 1000, and 2000 PPD (200, 500, 900, 2000 and 5000 gms/hr and 10, 20, and 40 kg/hr) using only four (4) different valve plugs. Model 7009 – Capacities to 500 PPD Model 7010 – Capacities of 1000 and 2000 PPD The REGAL SMARTVALVE shall include a four phase linear, heavy duty stepper motor, feedback potentiometer and modulating gas flow control valve. The circuitry shall produce a series of pulses such that the motor position is a function For maximum system accuracy, and to compensate for manufacturing tolerance differences in the various parts making up the complete gas feed system, the SMARTVALVE shall include a program by which the factory and/or the end user can easily “linearize” the valve plug position to precisely match the digital display and the system metering tube reading at 25%, 50%, 75%, and 100% of the gas feed system’s capacity. If a mistake is made while “linearizing” the SMARTVALVE causing settings to fall outside acceptable values, the SMARTVALVE must contain a program whereby the operator can easily reset “typical linear electrical values” by simply pressing two (2) keypad buttons at the same time. For further overall system accuracy, and because some systems require a faster response than others, the SMARTVALVE shall include a program by which the factory and/or the end user can easily decrease or increase the speed of response of the stepper motor from one motor revolution every ten (10) seconds to one motor revolution every one (1) second. All REGAL SMARTVALVEs shall include a manual feed rate adjustment knob with indicator pin and plate for use during power outages. This feature shall give the operator four (4) ways to operate the SMARTVALVE; fully automatic, electric/manual and two (2) forms of only manual control (manual via the adjustment knob on the SMARTVALVE, and manual via the rate adjustment valve furnished as part of the gas feed system.) Should an electrical surge, etc. upset or scramble the program settings, the operator MUST be able to reload TYPICAL VALUES into the microprocessor by pressing and holding one keypad button while reapplying AC electrical power to the SMARTVALVE. SERIES 7009/7010 SMARTVALVE™ DIMENSIONS If the REGAL SMARTVALVE is not receiving an analog input signal or, if the signal wires are reversed or, if the analog signal is too high, the digital display shall indicate these conditions without the need of meters or test equipment. The REGAL SMARTVALVE shall also include an “averaging” parameter that can easily be used to smooth out fluctuations caused by the flowmeter and/or the flowmeter transmitter. The SMARTVALVE shall include a serial communications output producing a digital 20 mA current loop output. This program is accessed through the “Engineering” menu and provides two (2) choices (Cont or F dU.) Cont = A continuous output of valve plug position in PPD. F dU = Full duplex providing the user with full control of the SMARTVALVE from a remote site. If the serial communications interface to field mounted devices requires analog rather than digital inputs, the optional REGAL Model 7600 Serial to Analog Converter can be used to convert the “continuous” digital output to a 4-20 milliamp analog output representing instantaneous gas feed rate in PPD. Operator interface in all program modes and the operating mode shall be via a four button keypad. The REGAL SMARTVALVE shall include the following easy to read digital displays and annunciator LEDs to indicate the following conditions: A. Water flow process variable in actual numbers or, as a percent of flow. B. Residual process variable in PPM or ORP values. C. Setpoint value. D. Valve plug position in PPD. E.

No. 806-5 SPECIFICATIONS 7000 REGAL SERIES 7000 SMARTVALVE ™ 4. “ F e e d F o r w a r d D e - C h l o r i n a t i o n ” will require the use of two REGAL SMARTVALVES, with the first valve used to disinfect the water supply with chlorine and the second valve used to remove the chlorine residual with sulfur dioxide before the water returns to its natural environment. As in the case with “Compound Loop Control,” continuous signals will be sent to the SMARTVALVES from both a water flow meter and a residual analyzer. The first point of application (chlorine) will be located between the flow meter and the analyzer while the second point of application (sulfur dioxide) will be located downstream from the residual analyzer. GENERAL The REGAL Series 7000 SMARTVALVE™ shall be a modular system component capable of automatically regulating the chemical flow rate of a REGAL Gas Feed System. The SMARTVALVE will operate in response to standard analog input signals (4-20 milliamp DC) from field mounted transmitting devices such as water flow meters, residual analyzers, ORP monitors and/or contact closures from pump circuits. The basic REGAL SMARTVALVE shall be available in capacities ranging from 10 to 2000 PPD and will be used for either “Flow Proportional” or “Step Rate” Control Schemes (see descriptions below). The following models and capacities will be available: Model 7001 – Flow Proportional (10 to 500 PPD) Model 7002 – Step Rate (10 to 500 PPD) Model 7006 – Flow Proportional (1000/2000 PPD) Model 7007 – Step Rate (1000/2000 PPD) 1. “Flow Proportional Control” should be used whenever the water flow rate varies but the quality of the water remains constant. In this control scheme, the SMARTVALVE will automatically regulated the chemical flow rate relative to the varying water flow. The required ratio of chemical to water flow will be determined and set by the operator. 2. “Step Rate Control” should be used in applications where fixed speed pumps (up to four) are used to move the water to be treated from multiple water lines into one common line. The SMARTVALVE will receive on/off signals from the pump circuits and respond by automatically adjusting the valve plug position based upon which, and how many pumps are currently running. A more versatile, enhanced version of the REGAL SMARTVALVE shall be capable of operating in four different Control Schemes (described below). The following models and capacities will be available: Model 7009 – 10 to 500 PPD Model 7010 – 1000/2000 PPD 1. “ Flow Proportional Control”. See previous explanation. 2. “Residual Only Control” should be used when the water flow rate remains constant but the water quality varies. The SMARTVALVE receives 4-20 milliamp signals from a residual analyzer (located downstream from the point of application) and responds by automatically adjusting the gas feed rate to maintain the desired chemical residual. 3. “Compound Loop Control” is simply a combination of both “Flow Proportional” and “Residual Only” Control Schemes. It should be used when both the water flow rate and the water quality vary. In this scheme, the SMARTVALVE will continuously receive signals from both a water flow meter (located upstream from the point of application) and a residual analyzer (located downstream). The SMARTVALVE will respond by automatically adjusting the gas feed rate according to both signals to maintain the desired chemical residual. SPECIFICATIONS The REGAL SMARTVALVE shall be available in a total of eight (8) maximum capacities:10, 25, 50, 100, 250, 500, 1000 and 2000 PPD with relative metric equivalents of 200, 500, 900, 2000, 5000 gms/hr and 10, 20, 40 kg/hr. The REGAL SMARTVALVE shall include a four phase linear, heavy duty stepper motor, feedback potentiometer and modulating gas flow control valve. The circuitry will produce a series of pulses such that the motor position is a function of the number of pulses generated. The shaft direction will be a function of phase sequence while the speed will be a function of pulse ratio. The rotary motion of the motor will be converted into the linear motion required to drive the valve plug. The valve plug shall move a total distance of one inch (1") for all capacities based on a maximum of sixteen revolutions of the stepper motor. Each motor pulse will move the lead screw and valve plug linearly a maximum of 0.0003125 inches. The SMARTVALVE shall include a program by which the factory and/or the end user can “linearize” the valve’s digital display to precisely match the gas feed system’s metering tube reading. The SMARTVALVE shall also include a program by which the factory and/or end user can easily increase or decrease the speed of response of the stepper motor from one half (0.5) to ten (10) seconds per revolution. SERIES 7000 SMARTVALVE™ DIMENSIONS An averaging parameter in the “configuration mode” will prevent motor “chatter” by allowing for slight signal fluctuations transmitted from the flow meter and/or residual analyzer. The SMARTVALVE shall provide a total of four (4) means of operation: 1. Fully Automatic. 2. Electric/Manual via an adjustment knob used to change the gas feed rates as shown on the PLED screen. 3. Manual via the adjustment knob which drives the lead screw of the valve plug. A pin attached to the lead screw will indicate the gas feed rate adjustment. 4.

The chlorine flow rate is manually adjusted and is regulated by a spring opposed diaphragm regulator which also contains the safety shut-off valve. Vacuum is provided by a highly efficient water operated ejectpr which is close coupled with the chlorine solution diffuser. The ejector assembly contains a back flow check valve.

APPLICATION The Model 210 is designed to handle the vast majority of water treatment requirements. CAPACITIES Dual scale metering tubes with maximum capacities of 4, 10, 25, 50 and 100 pounds per 24 hrs. of chlorine gas with corresponding metric scales of 75, 200, 500, 900 and 2000 grams per hr. Minimum feed rate is 1/20th of maximum. FLOW RATE ADJUSTMENT Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate. SAFE VACUUM TUBE TO EJECTOR GATE VALVE EJECTOR REQUIREMENTS SPECIFICATIONS The standard ejector is designed to withstand static back pressures in excess of 200 psig (14.1 kg/cm2). However, due to the potential for "water hammer" in high pressure on-off systems and special booster pump considerations, it is recommended that a factory representative, or Chlorinators Incorporated be consulted regarding installation details on systems over 100 psig (7 kg/cm2). The amount of water required to operate the ejector depends upon the chlorine feed rate, water back pressure and water supply pressure available. Generally, the higher the chlorine flow and higher back pressure the greater the water flow is needed. The chlorinator shall be a REGAL Model 210 manufactured by Chlorinators Incorporated, Stuart, Florida, with a maximum capacity of 100 lbs./24 hrs (2000 gms/hr). It will be a vacuum operated solution feed type and mount directly on the chlorine cylinder valve by means of a positive yoke type clamp having an integral tightening screw with slide-bar handle. All regulating, metering, flow adjusting and safety functions shall be incorporated in the cylinder mounted unit. The inlet safety shut-off/vacuum regulating valve shall be of capsulated construction, easily removable as a unit from the outlet side of the yoke for ease of inspection, cleaning or maintenance. Vacuum shall be created by an ejector assembly connected directly to the chlorine solution diffuser. The assembly shall consist of a single piece venturi-recovery throat to prevent mis-alignment; also, a back flow check valve to prevent water from entering the gas system. The check valve shall be of positive, tight shut-off, unitized design not requiring springs or diaphragms for tight closing. OPERATION The chlorinator is clamped on the chlorine cylinder valve. The ejector assembly is normally attached to the solution diffuser at the point of injection (it may be wall mounted, but this is not recommended). A vacuum line connects these two units. Water, under pressure is forced through the ejector nozzle which creates a strong vacuum in the ejector body. This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet. The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted back to the chlorinator through the vacuum line; then through the rate valve and the flow meter and to the back of the diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring loaded inlet regulating valve to allow chlorine to enter from the cylinder. The chlorine passes through the flow rate indicating meter, flow rate adjusting valve and to the ejector. SERVICE Most service problems can be handled by the user, with no special tools. If that is not possible, or desirable, the chlorinator and ejector assembly can be shipped to the factory for overhaul and retest to like-new condition for a reasonable single service charge. If the unit cannot be taken out of service, we will send an “exchange” unit. The REGAL Model 216 Automatic Switchover Gas Chlorinator is a totally vacuum-operated system which is designed to automatically switch the chlorine feed from an empty cylinder to a full cylinder. It is also designed to provide system-backup. Should a problem develop with either vacuum regulator, chlorination can be continued. The chlorinators are of the vacuum-operated solution-feed type, designed for mounting directly on a chlorine cylinder valve. The switchovers are selfactuating, eliminating the need for a separate switchover module. A separate gas flow meter and rate control valve panel may be located wherever it is most convenient for the operator and connected between the vacuum regulator junction at the pressure relief (vent) valve, and the ejector, by means of safe vacuum tubing. The ejector assembly contains a back flow check valve. Chlorine gas flow rate is regulated by a springopposed diaphragm regulator which is also the automatic safety shut-off valve. Should vacuum be interrupted for any reason anywhere in the system the safety shutoff/inlet valve immediately closes, shutting off the chlorine supply from the cylinder. A pressure relief valve designed to “vent” the system also provides a central interconnection point for the vacuum tubing. OTHER IMPORTANT FEATURES • System Back-up — Each cylinder’s chlorinator has its own vacuum regulating diaphragm and safety/inlet valve insuring that chlorination can be continued if service should be required on either chlorinator. • Corrosion-resistant, Factory-adjusted Detent Mechanism — Detent does not require any field adjustment assuring that cylinder switchover will occur at the proper time, and that all available gas in supply cylinder will be used. • In-Use/Stand-by Indication — Prominent indicator on face quickly tells which is the stand-by cylinder and which cylinder is in use. Optional flowmeter panels are available for applications where the feed rate must be known at the chlorinator and the flow meter/rate valve panel cannot be seen. CAPACITIES Dual scale metering tubes with maximum capacities of 4, 10, 25, 50 and 100 pounds per 24 hrs. of chlorine gas with corresponding metric scales of 75, 200, 500, 900 and 2000 grams per hr. FLOW RATE ADJUSTMENT Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate.

OPERATION The chlorinators are clamped onto the chlorine cylinder valves. The ejector assembly is normally attached to the solution diffuser at the point of injection. A vacuum line is connected from each cylinder unit to the wallmounted, pressure-relief (vent) valve, and a single vacuum line connects the outlet of the connector to a wall-mounted, flow-meter/rate valve panel. The ejector is connected to the rate valve panel with a single vacuum line. Water, under pressure, is forced through the ejector nozzle which creates a strong vacuum in the ejector body. This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet. The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted through the vacuum line to the rate valve and the flow meter; then through the connector on the pressure-relief (vent) valve and on to the back of the operating chlorinator diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring-loaded inlet regulating valve to allow chlorine to enter from the cylinder. The chlorine passes through the chlorinator, the pressure-relief (vent) valve connector and the flow rate indicating meter/flow rate adjusting valve to the ejector. When the operating cylinder starts to run out, the vacuum starts to build up in the system causing the diaphragm of the chlorinator on “stand-by” to be drawn back, overcoming a detent mechanism and opening the safety/inlet valve. This allows chlorine gas to be withdrawn from the “stand-by” cylinder to satisfy the increased system vacuum and the vacuum falls back to the operating level. The original supply cylinder also continues to feed until it is empty, virtually assuring that there will be no interruption of chlorination and that full use will be made of all available chlorine. This also reduces the possibility and risk of returning cylinders with some remaining gas to the supplier. SPECIFICATIONS The chlorinator system shall be a vacuumoperated, solution-feed type and shall automatically switch the chlorine supply from an empty cylinder to a full cylinder. It shall be REGAL Model 216 manufactured by Chlorinators Incorporated, Stuart, Florida, and shall have a maximum capacity of 100 lbs./24 hrs (2000 gms/hr). The Model 216 Vacuum-Operated Automatic Switchover Chlorinator shall consist of the following components: Two (2) automatic switchover vacuum regulators for mounting directly on chlorine gas cylinder valves, one (1) pressure-relief (vent) valve, one (1) chlorine gas flow meter panel with rate valve, & one (1) ejector/check valve assembly. The vacuum regulators shall mount directly onto the cylinder valve by means of a positive yoke type clamp having an integral tightening screw with slide bar handle. The main vacuumregulating diaphragm of each chlorinator shall have a minimum operating area of 13 sq. inches in order to achieve required accuracy and repeatability of the set chlorine flow rate. All metallic bolts shall mate with metallic threaded nuts or inserts. Plastic mating threads for metallic bolts shall not be acceptable. Each chlorinator vacuum regulator shall have its own diaphragm, safety-shutoff/inlet valve and switchover detent mechanism, thereby, allowing chlorination to continue should it become necessary to remove either vacuum regulator from service for cleaning or servicing. Switchover detent mechanism shall be made of corrosion-resistant materials and shall not require any field adjustment.

APPLICATION The Model 2101 Gas Chlorinators are designed to handle the vast majority of chlorine treatment requirements of medium to large water and wastewater treatment systems. Municipal water and sewer sysems are as easily treated as industrial systems. Most cooling water and process water applications can be handled by these chlorinators. Model 2101 is also ideal for "shock" treatment systems. CAPACITIES Dual scale metering tubes with maximum capacities of 1000 and 2000 pounds per 24 hours of chlorine gas with corresponding metric scales of 20 and 40 kilograms per hour. The minimum feed rate is 1/20th of maximum for each metering tube. The flow metering tubes are interchangeable and may be changed in the field. FLOW RATE ADJUSTMENT Manual adjustment is by means of a flow rate control valve located at the top of the flow meter/rate valve Model 2101 Gas Chlorinators are tested to give the best operation in the system being treated. Ejector assembly is chosen for, and tested to, the individual user's conditions. Generally, the amount of water (GPM) required to operate the ejector depends upon the chlorine flow rate, the ejector back pressure, and the water supply pressure which is available. In all cases, the minimum pressure differential and water flow for your installation should be determined prior to installation and start up. Refer to Application Bulletin 1009. OPERATION The vacuum regulator is clamped on the header valve of a chlorine cylinder or ton container manifold. It may also be clamped directly on to a chlorine ton container valve, using a TAY-200 adaptor, if used for intermittent or "shock" treatment for short periods of time (consult Chlorinators Incorporated). The ejector assembly is either wall mounted or supported by rigid pipe. A chlorine flow meter/rate valve panel is located between these two units and a vacuum lineconnects the three components. Water, under pressure is forced through the ejector nozzle which creates a strong vacuum in the ejector body. This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet. The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted back to the chlorinator vacuum regulator through the chlorine flow meter/rate valve panel by the vacuum line and acts against the back surface of the chlorinator diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring loaded inlet regulating valve to allow chlorine to enter from the pressurized source. The chlorine passes through the flow rate indicating meter, flow rate adjusting valve and to the ejector.

Vacuum shall be created by an ejector assembly connected directly to the chlorine solution diffuser. The assembly shall consist of a single piece venturi-recovery throat to prevent misalignment; also, a back flow check valve to prevent water from entering the gas system. The check valve shall be of positive, tight shut-off, unitized design not requiring springs or diaphragms on high back pressure systems. SERVICE Most service problems can be handled by the user, with no special tools. If that is not possible, or desirable, the chlorinator and ejector assembly can be shipped to the factory for overhaul and retest to like-new condition for a reasonable single service charge. If the unit cannot be taken out of service, we will send an “exchange” unit. The REGAL Model 226 Automatic Switchover Gas Chlorinator is a totally vacuum-operated system which is designed to automatically switch the chlorine feed from an empty cylinder to a full cylinder. It is also designed to provide system-backup. Should a problem develop with either vacuum regulator, chlorination can be continued. The chlorinators are of the vacuum-operated solution-feed type, designed for mounting directly on a chlorine cylinder valve. The switchovers are self-actuating, eliminating the need for a separate switchover module. A separate gas flow meter and rate control valve panel may be located wherever it is most convenient for the operator and connected between the vacuum regulator junction at the pressure relief (vent) valve, and the ejector, by means of safe vacuum tubing. The ejector assembly contains a back flow check valve. Chlorine gas flow rate is regulated by a spring-opposed diaphragm regulator which is also the automatic safety shut-off valve. Should vacuum be interrupted for any reason anywhere in the system the safety shut-off/inlet valve immediately closes, shutting off the chlorine supply from the cylinder. A pressure relief valve designed to “vent” the system also provides a central interconnection point for the vacuum tubing. OTHER IMPORTANT FEATURES • System Back-up — Each cylinder’s chlorinator has its own vacuum regulating diaphragm and safety/inlet valve insuring that chlorination can be continued if service should be required on either chlorinator. • Corrosion-resistant, Factory-adjusted Detent Mechanism — Detent does not require any field adjustment assuring that cylinder switchover will occur at the proper time, and that all available gas in supply cylinder will be used. • In-Use/Stand-by Indication — Prominent indicator on face quickly tells which is the stand-by cylinder and which cylinder is in use. Optional flowmeter panels are available for applications where the feed rate must be known at the chlorinator and the flow meter/rate valve panel cannot be seen. CAPACITIES Dual scale metering tube with maximum capacity of 250 pounds per 24 hrs. of chlorine gas with corresponding metric scales of 5000 grams per hr. or 5kg/hr. FLOW RATE ADJUSTMENT Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate. MATERIALS OF CONSTRUCTION All materials used in REGAL gas chlorinators have been carefully chosen for their excellent corrosion-resistant, ultra-violet-resistant properties plus their ability to withstand stresses far TON CONTAINER MOUNTED INSTALLATION WITH MODEL TAY-200 ADAPTOR greater than will be encountered in actual use. OPERATION The chlorinators are clamped onto the chlorine cylinder valves. The ejector assembly is normally attached to the solution diffuser at the point of injection. A vacuum line is connected from each cylinder unit to the wallmounted, pressure-relief (vent) valve, and a single vacuum line connects the outlet of the connector to a wall-mounted, flow-meter/rate valve panel. The ejector is connected to the rate valve panel with a single vacuum line. Water, under pressure, is forced through the ejector nozzle which creates a strong vacuum in the ejector body. This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet. The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted through the vacuum line to the rate valve and the flow meter; then through the connector on the pressure-relief (vent) valve and on to the back of the operating chlorinator diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring-loaded inlet regulating valve to allow chlorine to enter from the cylinder. The chlorine passes through the chlorinator, the pressure-relief (vent) valve connector and the flow rate indicating meter/flow rate adjusting valve to the ejector. When the operating cylinder starts to run out, the vacuum starts to build up in the system causing the diaphragm of the chlorinator on “stand-by” to be drawn back, overcoming a detent mechanism and opening the safety/inlet valve. This allows chlorine gas to be withdrawn from the “stand-by” cylinder to satisfy the increased system vacuum and the vacuum falls back to the operating level. The original supply cylinder also continues to feed until it is empty, virtually assuring that there will be no interruption of chlorination and that full use will be made of all available chlorine. REGAL MODEL 226 WALL-MOUNTED INSTALLATION This also reduces the possibility and risk of returning cylinders with some remaining gas to the supplier. SPECIFICATIONS The chlorinator system shall be a vacuum-operated, solution-feed type and shall automatically switch the chlorine supply from an empty cylinder to a full cylinder. It shall be REGAL Model 226 manufactured by Chlorinators Incorporated, Stuart, Florida, and shall have a maximum capacity of 250 lbs./24 hrs (5000 gms or 5kg/hr). The Model 226 Vacuum-Operated Automatic Switchover Chlorinator shall consist of the following components: Two (2) automatic switchover vacuum regulators for mounting directly on chlorine gas cylinder valves, one (1) pressure-relief (vent) valve, one (1) chlorine gas flow meter panel with rate valve, & one (1) ejector/check valve assembly. The vacuum regulators shall mount directly onto the cylinder valve by means of a positive yoke type clamp having an integral tightening screw with slide bar handle. The main vacuumregulating diaphragm of each chlorinator shall have a minimum operating area of 13 sq. inches in order to achieve required accuracy and repeatability of the set chlorine flow rate. All metallic bolts shall mate with metallic threaded nuts or inserts. Plastic mating threads for metallic bolts shall not be acceptable. Each chlorinator vacuum regulator shall have its own diaphragm, safety-shutoff/inlet valve and switchover detent mechanism, thereby, allowing chlorination to continue should it become necessary to remove either vacuum regulator from service for cleaning or servicing. Switchover detent mechanism shall be made of corrosion-resistant materials and shall not require any field adjustment.

No. 103-6 SPECIFICATION 250/256 REGAL GAS CHLORINATOR The REGAL Model 250 Chlorinator is a vacuum-operated solution feed type, designed for mounting on wall manifold or ton container when continuous chlorine feed rates up to 500 lbs. per 24 hours (10 kg/hr) is needed. The Model 250 may also be mounted directly on the valve of a 100 or 150 lb. chlorine cylinder and operated up to 500 lbs./24 hrs. for very short periods. The chlorine flow rate is manually adjusted. The chlorinator clamps directly to a chlorine header valve on the chlorine supply manifold or directly onto the REGAL TAY-200 ton container adaptor by means of a positive, heavy-duty yoke clamp. A highly efficient, water operated, vacuum-producing ejector is close coupled with the chlorine solution diffuser. The assembly contains a back flow check valve. Chlorine gas flow rate is regulated by a spring opposed diaphragm regulator which is also the safety shut-off valve. REGAL MODEL 250 WALL MOUNTED INSTALLATION TON CONTAINER INSTALLATION FEATURES The REGAL Model 250 incorporates the very best available materials with the latest technology in design and construction, to reduce maintenance, simplify construction, and improve operation. APPLICATION The Model 250 is designed to handle the vast majority of water treatment requirements. CAPACITIES Dual scale metering tube with maximum capacity of 500 pounds per 24 hrs. of chlorine gas with corresponding metric scales of 10 kg per hr. Minimum feed rate is 1/20th of maximum. FLOW RATE ADJUSTMENT Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate. REGAL MODEL 250 WALL MOUNTED INSTALLATION REGAL MODEL 250 TON CONTAINER MOUNTED INSTALLATION EJECTOR REQUIREMENTS SPECIFICATIONS The standard ejector is designed to withstand static back pressures in excess of 200 psig (14.1 kg/cm2). However, due to the potential for “water hammer” in high pressure on-off systems and special booster pump considerations, it is recommended that a factory representative, or Chlorinators Incorporated be consulted regarding installation details on systems over 100 psig (7 kg/cm2). The amount of water required to operate the ejector depends upon the chlorine feed rate, water back pressure and water supply pressure available. Generally, the higher the chlorine flow and higher back pressure the greater the water flow is needed.

No. 103-7 SPECIFICATIONS 3000 ™ REGAL SERIES 3000 GAS DETECTOR GENERAL The REGAL Series 3000 Gas Detector shall use microprocessor based electronics and shall be capable of accurately sensing and displaying the presence of free chlorine or free sulfur dioxide in the environment at levels below those mandated by OSHA throughout the working life of the sensor(s) used. The gas detector monitor enclosure shall be NEMA 4X. The sensor enclosure(s) shall be watertight, UL approved, and RFI/EMI protected. The single sensor gas detector shall include a single, isolated and unpowered 4-20 mA analog output circuit board; whereas the dual sensor unit shall include a dual, isolated and unpowered 4-20 mA circuit board. All REGAL Series 3000 Gas Detectors shall include six relay circuits. 2 WARNING relays 2 DANGER relays 1 HORN/FAILURE relay 1 LATCH relay The monitor shall continuously scan and display the sensor data using a multicolor bargraph indicator for each sensor to present both the current and un-reset peak gas concentrations. A three digit numeric display shall display the current gas concentration. For the dual sensor version, the numeric display shall present the two sensor outputs alternately at about 5 second intervals. An arrowhead LED indicator under each bargraph is used to indicate which sensor information is being presented numerically. A separate LED indicator shall show the gas each sensor is set up to monitor as it is presented. Dual sensor detectors can monitor one of the aforementioned gases at two different locations or, they can be configured to monitor both chlorine and sulfur dioxide. The two WARNING relays, the LATCH relay and the HORN/FAILURE relay are SPDT. The two DANGER relays are DPDT. All relays are rated at 10 amps @ 250 VAC and 50 or 60 Hz. The WARNING relays activate at 1 PPM for chlorine and at 2 PPM for sulfur dioxide. The DANGER relays activate at 3 PPM for chlorine and at 5 PPM for sulfur dioxide. On a single sensor unit, both WARNING relays and both DANGER relays activate during an appropriate alarm event. On a dual sensor unit, one WARNING relay and one DANGER relay is dedicated to each sensor. When the sensor is subjected to varying concentrations of gas, the monitor displays the actual concentration on the appropriate bargraph and the numeric display. As the concentration of gas increases, the internal alarm horn shall sound and the appropriate WARNING relays, HORN/FAILURE relay and LATCH relay (if latch time is set to 0) shall engage when passing the WARNING point. If the concentration of gas increases to the danger point, the internal horn and HORN/FAILURE relay will be reasserted if they had been silenced (turned OFF) and, the appropriate DANGER relays shall latch into the alarm state. The bargraph LED representing the highest detected level MUST stay lit even if the gas concentration decreases to let the user know they has a leak and, the magnitude of the leak even if it had cleared itself. The internal alarm horn and the HORN/FAILURE relay can be configured in the field via an electronic DIP switch in the monitor to "pulse" or be "on continuously" when activated by an alarm event. The horn and external alarm devices connected to the HORN/FAILURE relay can be silenced (turned off) by pressing the SILENCE keypad button. A RESET keypad button shall be provided to acknowledge and reset alarms once the problem has been corrected and the indications return to 0 PPM. The detector shall include a program to allow the user to easily test the condition of sensors and disable all alarm circuits for a timed 15-minute interval using the keypad. The user must also be able to perform a relay test, which will individually and sequentially activate, then deactivate the six relay circuits. Loss of signal from the sensor(s) results in a "Fail" message on the numeric display and a relay closure of the HORN/FAILURE relay. An off scale message "OFS" is also presented on the numeric display for full scale readings in excess of 10 PPM chlorine or 20 PPM sulfur dioxide. When the REGAL Series 3000 Gas Detector includes the OPTIONAL battery back-up module, and during primary power failures, all display illumination shall automatically be turned off to conserve battery power except for the BATTERY LED to let the user know the system is still functioning. All detection, alarm and relay functions continue to operate normally. If during the power outage, the user wishes to observe conditions on the bargraphs and the numeric display, he can turn on the displays for one sensor scan cycle by pressing any keypad button. The display then automatically turns off again to continue conserving battery power. The REGAL Series 3000 Gas Detector shall include a program to simplify calibrating the gas detector by using the keypad buttons. There shall be no need to go inside the enclosure for calibration. The calibration program shall automatically disable all alarm relay operations during the calibration process. If the operator does not wish to calibrate the detector but simply wants to check sensor condition by applying the appropriate gas to the sensor inlet, the detector MUST include a separate program by which the operator can use the keypad to disable all alarm circuits for a timed fifteen minute period while performing this test, then automatically again enable alarms. If a mistake is made during the calibration process, the user MUST be able to reset the detector back to factory specifications by pressing one keypad button.

SAFE VACUUM TUBE TO EJECTOR WATER SUPPLY TO EJECTOR PRODUCES VACUUM AND MIXES WITH WATER PRESSURE GAGE FEATURES VENT STRAINER GATE VALVE EJECTOR REQUIREMENTS SPECIFICATIONS The standard ejector is designed to withstand static back pressures in excess of 200 psig (14.1 kg/cm2). However, due to possibilities of water line "torque" in high pressure on-off systems, as well as special booster pump considerations, it is recommended that a factory representative, or Chlorinators Incorporated be consulted regarding installation details in systems over 100 psig (7 kg/cm2). Generally, the amount of water required to operate the ejector depends upon the ammonia flow rate. The higher the ammonia flow rate, the greater the water flow needed.

If the unit cannot be taken out of service, we will send an “exchange” unit. The REGAL Model 316 Automatic Switchover Gas Ammoniator is a totally vacuum-operated system which is designed to automatically switch the ammonia feed from an empty cylinder to a full cylinder. It is also designed to provide system-backup. Should a problem develop with either vacuum regulator, ammoniation can be continued. The ammoniators are of the vacuum-operated solution-feed type, designed for mounting directly on an ammonia cylinder valve. The switchovers are self-actuating, eliminating the need for a separate switchover mechanism. A separate gas flow meter and rate control valve panel may be located wherever it is most convenient for the operator and connected between the vacuum regulator junction at the pressure relief (vent) valve, and the ejector, by means of safe vacuum tubing. The ejector assembly contains a back flow check valve. Ammonia gas flow rate is regulated by a spring-opposed diaphragm regulator which is also the automatic safety shut-off valve. Should vacuum be interrupted for any reason anywhere in the system the safety shut-off/inlet valve immediately closes, shutting off the ammonia supply from the cylinder.

The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted through the vacuum line to the rate valve and the flow meter; then through the connector on the pressure-relief (vent) valve and on to the back of the operating ammoniator diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring-loaded inlet regulating valve to allow ammonia to enter from the cylinder. The ammonia passes through the ammoniator, the pressure-relief (vent) valve connector and the flow rate indicating meter/flow rate adjusting valve to the ejector. When the operating cylinder starts to run out, the vacuum starts to build up in the system causing the diaphragm of the ammoniator on “stand-by” to be drawn back, overcoming a detent mechanism and opening the safety/inlet valve. This allows ammonia gas to be withdrawn from the “stand-by” cylinder to satisfy the increased system vacuum and the vacuum falls back to the operating level. The original supply cylinder also continues to feed until it is empty, virtually assuring that there will be no interruption of ammoniation and that full use will be made of all available ammonia. This also reduces the possibility and risk of returning cylinders with some remaining gas to the supplier. SPECIFICATIONS The ammoniator system shall be a vacuumoperated, solution-feed type and shall automatically switch the ammonia supply from an empty cylinder to a full cylinder. It shall be REGAL Model 316 manufactured by Chlorinators Incorporated, Stuart, Florida, and shall have a maximum capacity of 100 lbs./ 24 hrs. (2000 gms/hr). The Model 316 Vacuum-Operated Automatic Switchover Chlorinator shall consist of the following components: Two (2) automatic switchover vacuum regulators for mounting directly on ammonia gas cylinder valves, one (1) pressure-relief (vent) valve, one (1) ammonia gas flow meter panel with rate valve, & one (1) ejector/check valve assembly. The vacuum regulators shall mount directly onto the cylinder valve by means of a positive yoke type clamp having an integral tightening screw with slide bar handle. The main vacuumregulating diaphragm of each ammoniator shall have a minimum operating area of 13 sq. inches in order to achieve required accuracy and repeatability of the set ammonia flow rate. All metallic bolts shall mate with metallic threaded nuts or inserts. Plastic mating threads for metallic bolts shall not be acceptable. Each ammoniator vacuum regulator shall have its own diaphragm, safety-shutoff/inlet valve and switchover detent mechanism, thereby, allowing ammoniation to continue should it become necessary to remove either vacuum regulator from service for cleaning or servicing. Switchover detent mechanism shall be made of corrosion-resistant materials and shall not require any field adjustment.

No. 1099-1 SPECIFICATION 710/716 REGAL GAS SULPHONATOR The REGAL Model 710 Sulphonator is a vacuum-operated, solution feed type, designed for mounting directly on a sulfur dioxide cylinder valve by means of a positive heavy duty yoke clamp. The sulfur dioxide flow rate is manually adjusted and is regulated by a spring opposed diaphragm regulator which also contains the safety shut-off valve. Vacuum is provided by a highly efficient water operated ejector which is close coupled with the sulfur dioxide solution diffuser. The ejector assembly contains a back flow check valve. REGAL MODEL 710 DIRECT CYLINDER MOUNTED GAS SULPHONATOR RATE VALVE INDICATOR POSITIVE CLAMP ON CYLINDER VALVE METERING TUBE PRECISE REGULATOR FOR FLOW SOLUTION DIFFUSER COUPLED TO EJECTOR VENT EJECTOR AND WATER MIXING CHAMBER WITH CHECK VALVE WATER SUPPLY TO EJECTOR PRODUCES VACUUM AND MIXES WITH WATER PRESSURE GAGE EJECTOR REQUIREMENTS FEATURES The REGAL Model 710 incorporates the very best available materials with the latest technology in design and construction, to reduce maintenance, simplify construction, and improve operation. APPLICATION The Model 710 is designed to handle the vast majority of water treatment requirements. CAPACITIES Dual scale metering tubes with maximum capacities of 4, 10, 25, 50 and 100 pounds per 24 hrs. of sulfur dioxide gas with corresponding metric scales of 75, 200, 500, 900 and 2000 grams per hr. Minimum feed rate is 1/20th of maximum. FLOW RATE ADJUSTMENT Manually adjustable by means of a flow rate control valve located at the top of the flow meter. Flow rate is then regulated by a special spring-opposed diaphragm operated valve. The system is automatic. It will go off and on as the ejector water is turned off and on and will always return to the pre-set flow rate. The standard ejector is designed to withstand static back pressures in excess of 200 psig (14.1 kg/cm2). However, due to the potential for "water hammer" in high pressure on-off systems and special booster pump considerations, it is recommended that a factory representative, or Chlorinators Incorporated be consulted regarding installation details on systems over 100 psig (7 kg/cm2). The amount of water required to operate the ejector depends upon the sulfur dioxide feed rate, water back pressure and water supply pressure available. Generally, the higher the sulfur dioxide flow and higher back pressure the greater the water flow is needed. OPERATION The sulphonator is clamped on the sulfur dioxide cylinder valve. The ejector assembly is normally attached to the solution diffuser at the point of injection (it may be wall mounted, but this is not recommended). A vacuum line connects these two units. Water, under pressure is forced through the ejector nozzle which creates a strong vacuum in the ejector body. This pulls gas into the ejector through a special back-flow check valve and then into the nozzle outlet. The gas mixes with the ejector water and is discharged through the diffuser into the water being treated. The ejector vacuum is transmitted back to the sulphonator through the vacuum line; then through the rate valve and the flow meter and to the back of the diaphragm. With sufficient vacuum, the diaphragm moves backward, opening the spring loaded inlet regulating valve to allow sulfur dioxide to enter from the cylinder. SAFE VACUUM TUBE TO EJECTOR STRAINER GATE VALVE The sulfur dioxide passes through the flow rate indicating meter, flow rate adjusting valve and to the ejector. SPECIFICATIONS The sulphonator shall be a REGAL Model 710 manufactured by Chlorinators Incorporated, Stuart, Florida, with a maximum capacity of 100 lbs./24hrs. (2000gms/hr.). It will be a vacuum operated solution feed type and mount directly on the sulfur dioxide cylinder valve by means of a positive yoke type clamp having an integral tightening screw with slide-bar handle. All regulating, metering, flow adjusting and safety functions shall be incorporated in the cylinder mounted unit. The inlet safety shut-off/vacuum regulating valve shall be of capsulated construction, easily removable as a unit from the outlet side of the yoke for ease of inspection, cleaning or maintenance. Vacuum shall be created by an ejector assembly connected directly to the sulfur dioxide solution diffuser. The assembly shall consist of a single piece venturi-recovery throat to prevent mis-alignment; also, a back flow check valve to prevent water from entering the gas system. The check valve shall be of positive, tight shut-off, unitized design not requiring springs or diaphragms for tight closing. SERVICE Most service problems can be handled by the user, with no special tools. If that is not possible, or desirable, the sulphonator and ejector assembly can be shipped to the factory for overhaul and retest to like-new condition for a reasonable single service charge. If the unit cannot be taken out of service, we will send an “exchange” unit. The REGAL Model 716 Automatic Switchover Gas Sulphonator is a totally vacuum-operated system which is designed to automatically switch the sulfur dioxide feed from an empty cylinder to a full cylinder. It is also designed to provide system-backup. Should a problem develop with either vacuum regulator, sulphonation can be continued. The sulphonators are of the vacuum-operated solution-feed type, designed for mounting directly on a sulfur dioxide cylinder valve. The switchovers are self-actuating, eliminating the need for a separate switchover module. A separate gas flow meter and rate control valve panel may be located wherever it is most convenient for the operator and connected between the vacuum regulator junction at the pressure relief (vent) valve, and the ejector, by means of safe vacuum tubing. The ejector assembly contains a back flow check valve. Sulfur dioxide gas flow rate is regulated by a spring-opposed diaphragm regulator which is also the automatic safety shut-off valve. Should vacuum be interrupted for any reason anywhere in the system the safety shut-off/inlet valve immediately closes, shutting off the sulfur dioxide supply from the cylinder. A pressure relief valve designed to “vent” the system also provides a central interconnection point for the vacuum tubing. OTHER IMPORTANT FEATURES • System Back-up – Each cylinder’s sulphonator has its own vacuum regulating diaphragm and safety/inlet valve insuring that sulphonation can be continued if service should be required on either sulphonator. • Corrosion-resistant, Factory-adjusted Detent Mechanism – Detent does not require any field adjustment assuring that cylinder switchover will occur at the proper time, and that all available gas in supply cylinder will be used. • In-Use/Stand-by Indication – Prominent indicator on face quickly tells which is the stand-by cylinder and which cylinder is in use. Optional flowmeter panels are available for applications where the feed rate must be known at the sulphonator and the flow meter/rate valve panel cannot be seen. CAPACITIES Dual scale metering tubes with maximum capacities of 4, 10, 25, 50 and 100 pounds per 24 hrs. of sulfur dioxide gas with corresponding metric scales of 75, 200, 500, 900 and 2000 grams per hr.

When the operating cylinder starts to run out, the vacuum starts to build up in the system causing the diaphragm of the sulphonator on “stand-by” to be drawn back, overcoming a detent mechanism and opening the safety/ inlet valve. This allows sulfur dioxide gas to be withdrawn from the “stand-by” cylinder to satisfy the increased system vacuum and the vacuum falls back to the operating level. The original supply cylinder also continues to feed until it is empty, virtually assuring that there will be no interruption of sulphonation and that full use will be made of all available sulfur dioxide. This also reduces the possibility and risk of returning cylinders with some remaining gas to the supplier. The sulphonator system shall be a vacuumoperated, solution-feed type and shall automatically switch the sulfur dioxide supply from an empty sulfur dioxide source to a full sulfur dioxide source. It shall be REGAL Model 756 manufactured by Chlorinators Incorporated, Stuart, Florida, and shall have a maximum capacity of 500 lbs./24 hrs (10kg/hr). The Model 756 Vacuum-Operated Automatic Switchover Sulphonator shall consist of the following components: Two (2) automatic switchover vacuum regulators for mounting directly on sulfur dioxide gas cylinder valves, one (1) pressure-relief (vent) valve, one (1) sulfur dioxide gas flow meter panel with rate valve, & one (1) ejector/check valve assembly. The vacuum regulators shall mount directly onto the cylinder header valve or directly onto the Regal TAY-200 ton container adaptor by means of a positive yoke type clamp having an integral tightening screw with slide bar handle. The main vacuum-regulating diaphragm of each sulphonator shall have a minimum operating area of 13 sq. inches in order to achieve required accuracy and repeatability of the set sulfur dioxide flow rate. All metallic bolts shall mate with metallic threaded nuts or inserts. Plastic mating threads for metallic bolts shall not be acceptable. Each sulphonator vacuum regulator shall have its own diaphragm, safety-shutoff/inlet valve and switchover detent mechanism, thereby allowing sulphonation to continue should it become necessary to remove either vacuum regulator from service for cleaning or servicing. Switchover detent mechanism shall be made of corrosion-resistant materials and shall not require any field adjustment.

No. 103-5 BULLETIN NO. 0278-3 Comparative safety of Chlorine, Calcium Hypochlorite and Sodium Hypochlorite INTRODUCTION: With the greatly increased use of chlorine and chlorine compounds, there appears to be at the same time less and less understanding and concern about safe handling, storage and use. Great respect, and often times fear, is sill the general attitude in regards to chlorine gas. Calcium hypochlorite and sodium hypochlorite are treated quite lightly in regards to care and safety when, in fact, they have moved far ahead of chlorine gas in the direct or indirect cause of death, injury and property damage. A good example of the lack of understanding is the fact that so many health and engineering organizations insist upon chlorine gas cylinders and equipment being located in a separate, well-ventilated room – while hypochlorination supplies and equipment are allowed to be placed in any convenient location. For greatest safety, all-chlorine and chlorine compounds should be placed in separate, well-ventilated rooms, as well as the feeding equipment. In the case of hypochlorites, even extra precaution should be taken. GENERAL: Chlorine is an element and, when supplied in its basic form, is a liquefied gas under pressure. Chlorine in pressurized containers is in the form of both liquid and gas. The element chlorine is often times combined with other compounds to make it easier to package and handle, and to be able to use other types of feeding equipment than required with gas chlorine. The most common powder form (and tablet form) is calcium hypochlorite. The liquid preparation is sodium hypochlorite, which is available in various strengths and is known as bleach of laundry bleach. Chlorine gas, itself, is primarily a respiratory irritant depending upon the concentration in the atmosphere, as well as the duration of the exposure, it can be only mildly irritating or, in extreme cases, can even cause death. Chlorine gas is not just obtained from a gas cylinder, but is also given off from calcium hypochlorite and sodium hypochlorite. This means that regardless of the form in which chlorine is obtained, the fumes themselves are equally dangerous. The United States Bureau of Mines indicated that most people cannot detect chlorine in the atmosphere at a concentration of less than about 3.5 pounds of chlorine per million pounds of air (PPM). However, they further state that at only 5 PPM the mixture is noxious and impossible to breathe for more than several minutes. At slightly higher values than this, you run into irritation, coughing and truly hazardous conditions. You can readily see from these values that anytime you can smell chlorine, you are in a hazardous atmosphere and should not remain. Chlorine gas, itself, is neither explosive nor flammable. It is, however, a very strong oxidizing agent and will react with almost all elements and with many inorganic or organic compounds. In doing so, the reaction usually gives off heat. With chlorine gas obtained from cylinders, there is very little fire hazard. On the other hand, calcium and sodium hypochlorite appear to be non-hazardous, but often react violently when in contact with many ordinary materials – and/or with heat, spark or flame present. Moist chlorine is very highly corrosive as a result of the formation of hydrochloric and hypochlorous acids, and neither equipment nor supplies – in any form – should be located so that chlorine will come in contact with electrical equipment or other equipment that will be damaged by corrosion. LIQUID CHLORINE (CHLORINE GAS): Pure chlorine is shipped in steel containers in which the chlorine is both in the liquid and gas phase. Since the chlorine has been thoroughly cleaned and dried before being placed in the containers, it is non-corrosive to the steel. The chlorine cylinder valves are of a very heavy construction and are additionally protected during handling by a heavy steel hood. Since chlorine in the cylinders is under pressure, and the pressure increases with temperature, the cylinders are further protected from bursting by a fusible plug which is designed to melt at between 158°F and 165°F. In the case of fire, this plug would melt allowing the chlorine gas to escape, rather than allowing pressure to build up, which might eventually rupture the cylinder and cause pieces of metal to be thrown out. Here, basically, are the more common safety rules for handling and storage: (1) When moving cylinders, the valve protection hood should be in place at all times. (2) Cylinders must not be dropped or struck with any force. (3) A safety chain or strap should be placed around the cylinder and affixed to a wall, pipe, etc. to prevent tipping over in the event the cylinder is accidentally hit or pushed. (4) Cylinders should be stored in an upright position. (5) Cylinders should not be stored near a ventilating system, passageways, or below ground in unventilated rooms. (6) Grease or oil should never be on, or around, chlorine fittings or connections. (7) If there is any indication of the presence of chlorine in the air, immediate action should be taken to correct the condition. Chlorine leaks that are left alone will always get worse. (8) If an extensive chlorine leak is found, all persons should be kept away from the area – preferably up-wind and at a higher level. CALCIUM HYPOCHLORITE: Calcium hypochlorite is most usually supplied as a powder or in small granular form, although in some cases it is compressed into tablets. In these forms, it can more easily be packaged in small quantities, can more easily be transported, and is relatively simple to handle if very careful precautions are taken. Contrary to popular belief, this “safe” form of chlorine causes a great number of accidents of all types. The innocence of appearance and packaging can be very misleading. Although chlorine is purchased in this form ‘supposedly’ for ease of handling and safety, the opposite is often true and the cost of the compound itself is at least three or four times as much per pound of chlorine as compared to chlorine purchased in the pure form. Some health agencies, engineers, and many users often feel that this form of chlorine supply is safe and simple to handle, but in truth it is far more hazardous than chlorine gas due to lack of understanding and suitable precautions. Examine closely the care and handling rules which are summarized from the basic information put out by the manufacturers: (1) Never mix calcium hypochlorite with anything but water. (2) Store in a cool, clean, dry area in the original container and always keep covered. (Most safe containers have a plastic bag liner which should not be removed and which should also be carefully closed and sealed.) (3) The storage area should be clean and removed from any combustible material and should not be located where chlorine fumes will cause corrosion to equipment. (4) Metal drums should be kept upright and should not be dropped, rolled or skidded. (5) When measuring calcium hypochlorite, you should use only a plastic, glass or enameled measuring device that is completely clean, dry and free of all foreign matter. (6) Calcium hypochlorite, as a strong oxidizing agent, must not be brought into contact with heat, acids or any combustible materials. These materials include paper, rags, beverages, tobacco, oil base products, etc. Matches, fire, lighted cigarettes and any form of heat must be kept away. (7) Whenever handling calcium hypochlorite, the hands must be clean and dry, and gloves should never be worn. Hands should be washed after handling. (8) Never permit calcium hypochlorite to contact the eyes. Any spilled calcium hypochlorite should immediately be flushed thoroughly with water. (9) Always rinse empty containers thoroughly with water. Small oversight in adhering strictly to the rules of safe handling of calcium chlorite can prove disastrous. There have been several occurrences where a new, sealed container dropped while unloading has caused explosion and fire which destroyed property and put many people, severely burned, in the hospital. Almost instantaneous explosion has occurred due to oily rags, banana peels, etc. being thrown into open containers of calcium hypochlorite. The reaction of a lit cigarette near or thrown into, a partially filled container can be quite violent. An oily rag, wad of paper or other combustible can be equally as serious. Motels have burned down, storehouses completely destroyed, and many people seriously injured from careless handling and storage of this material. Unfortunately, many accidents have occurred for unexplained reasons while operators were simply dipping a supply from the container or carrying a supply in the same manner that they had hundreds of times before – but suddenly there was a violent explosion. SODIUM HYPOCHLORITE: Sodium hypochlorite is a liquid supplied in various strengths of available chlorine. Again, we are interested only in the amount of chlorine required and in ease of handling. Common household laundry bleach is 5.25% available chlorine by weight. Solutions of approximately two and three times this concentration are available. In this form, the chlorine solution is generally supplied in glass or plastic containers and is relatively east to handle, although the cost as compared to pure chlorine is there to ten times as much depending upon the source and the concentration. Since sodium hypochlorite is a liquid, the hazards of fire and chlorine fumes are often underestimated and the same basic rules of safety as given above for calcium hypochlorite should be followed. Many accidents and deaths have occurred with even the relatively weak household bleach, but individual instances are not highly publicized and the hazard often overlooked. Here are some of the basic rules in addition to those listed above: (1) Store in a cool, dark area away from possible falling objects or physical damage. (2) Avoid contact of sodium hypochlorite with the eyes or with the skin. (3) Keep container tightly closed and keep away from combustible materials. (4) If spilled, wash down thoroughly and do not allow to remain in contact with cloth, paper, oil products or other combustible matter. (5) Keep containers away from heat and fire. (6) Never use in conjunction with acids, vinegar, toilet bowl cleaners or any other cleaning agents. The use of sodium hypochlorite as a bleaching and cleaning agent – such as in the home – has caused several deaths when used along with other agents which released chlorine fumes. Fires have occurred where rags and other combustible materials soaked with sodium hypochlorite have been allowed to stand and/or where a heat source may have been present. CONCLUSION: Chlorine as a gas has been feared and/or treated with respect primarily due to its use during World War I as a poison gas. No one doubts its toxicity or its potential hazard and, therefore, it is usually treated with respect. Most people do not know the true facts about chlorine and its compounds and therefore grossly overestimate the hazards of liquid chlorine (chlorine gas) and oversimplify the hazards connected with its compounds such as calcium and sodium hypochlorite. Government reports on the many tens of thousands of gas cases during World War I are remembered, but it is overlooked that only about two thousand cases were from chlorine gas and that only seven deaths occurred. Since chlorine remains as an everyday word, it is forgotten that mustard gas, phosgene and other gases were actually the problem. In addition, newspapers, magazines and other reporting media tend toward sensationalism which makes accidents involving a large number of people nationally important. Individual accidents have only local importance. In several years there have been chlorine gas leaks in public locations where dozens or more than a hundred people have been involved, and this received national publicity. Follow-up of these incidents was not as publicized and where chlorine gas was involved you find very little news – since recoveries were complete, quick and injuries comparatively negligible. Large fires, serious burnings and extensive damage caused by calcium or sodium hypochlorite are usually reported locally and do not receive much more publicity than a local car accident. They do not involve a large number of people. Unfortunately, the reporting sill refers to chlorine or chemicals rather than specifically to the form of compound that was involved. Local reports told the following: “A large fire completely destroyed a motel in southern California” – “Three men were very seriously burned when unloading powdered chlorine in Toledo” – “a swimming pool distributor’s ware house was destroyed by a fire in Texas” – “a bath house and filter room in St. Louis were destroyed by fire with injury to several when powdered chlorine ignited” – “two deaths in Illinois of housewives attributed to household bleach used in conjunction with other cleaning fluids.” These are only a few of the many accident cases that occur every year when using calcium or sodium hypochlorite with disregard for their hazard. Statistically and actually, chlorine gas is the least hazardous and safest form of chlorine available today, while at the same time being the most economical. Antiquated regulations and general dissatisfaction with chlorine gas were based primarily upon very high-priced equipment, extremely expensive maintenance and complication of operation. Modern technology and improved materials have eliminated these drawbacks, but lack of education in regards to safety and modern equipment has condoned practices that are well behind the times.

No. 604-2 chlorinators incorporated POULTRY & LIVESTOCK DRINKING WATER HOW TO ASSURE A CORRECT FREE CHLORINE RESIDUAL EXISTS AT ALL TIMES. In order to always have a properly chlorinated water supply, chlorine needs to be injected and thoroughly mixed into a moving body of water, which is why chlorination occurs only when the well pump or pumps are on and running. The moving water then becomes the vehicle that takes the chlorine throughout the distribution system. When you first add chlorine to the water, some of the chlorine is quickly consumed in satisfying the chlorine demand. Enough chlorine must be added to assure an excess exists after the demand is satisfies and remains in the water at all times as free chlorine residual. The free chlorine residual remaining assures that the water is properly disinfected throughout the entire drinking water line and that no infiltration, stagnation, or recontamination has occurred. To assure your poultry and livestock drinking water is properly disinfected at all times, the water MUST be periodically tested to assure that a free chlorine residual exists. For example, many poultry growers have reported benefits with free chlorine residual levels between 1.0 PPM and 5.0 PPM. This can sometimes be a difficult task due to the fact that each drinker line is dead-ended. Water is removed from these lines only when the animals are drinking. To further compound the issue, water is removed from many intermediate drinker locations along the individual lines and not necessarily at the ends of each line. The water can be trapped and become stagnant as the free chlorine residual is consumed. To prevent this condition, the end of each line should have a sampling/flush valve. To periodically test the water, a good-quality chorine residual test kit with fresh reagents is needed. These kits are easy to use following the instructions provided and are generally capable of testing for free as well as total chlorine residuals. Free chlorine residual is needed since it provides quicker bacterial kill using minimal amounts of chlorine. Chlorine residual tests should always be taken at the furthest end of each drinker line. To perform a residual test; 1. Slowly open the sampling/flush valve at the end of the line to be tested. 2. Following the instructions provided with the chlorine residual test kit, rinse the sample water vial provided with the test kit a few times with the water to be sampled, then fill the vial with the proper volume of sample water. 3. Add the appropriate quantity of free chlorine residual reagent to the sample water again following the instructions provided with the test kit. 4. Determine the free chlorine residual level existing in the sample water. If the free chlorine measured is less than 1.0 PPM and no one has changed the chlorine gas feed rate to cause this condition; 5. Open the sampling/flush valve fully, allowing the water to be flushed outside to an appropriate drain location. The flushing should continue long enough so that the well pump and chlorinator turn on in order to bring a freshly chlorinated supply of water into the line while the water is draining. 6. After an appropriate drain time interval, close the sampling/flues valve then repeat steps #1 through #4 above until the desired free chlorine residual is obtained. Adjust the chlorinator gas feed rate if necessary to obtain the correct reading. 7. Proceed to the next drinker line and repeat this procedure. Continue until all lines have been tested. Residual testing of the drinking water should be done at least once per day for each drinker line. chlorinators incorporated 1044 S.E. Dixie Cutoff Road Stuart, Florida 34994-3436 U.S.A.

PURE AND SIMPLE. Pub. No. 1004-1 Bulletin 0587-4 chlorinators incorporated CHLORINE VACUUM LINES VERSUS SOLUTION LINES (Chlorine Solubility in Water) Even though the concept of the direct – cylinder – mounted gas chlorinator utilized with a remote ejector, close coupled to the application point, has over forty to forty-five years of proven history, there still exists a great deal of confusion and misinformation regarding desirability of avoiding chlorine solution lines wherever possible. Chlorine is only slightly soluble in water. Theoretically, only about 0.7% chlorine can be dissolved in water at 68 degrees F (20 degrees C). Practical solubility, which requires considerable mixing and time, is about half this value. In conventional solution feed chlorinators, there is not sufficient time or mixing in the ejectors and solution lines to get even this practical solubility. As temperature increases, the solubility drops off very rapidly. The insolubility of chlorine in water was a major reason for the development of a vacuum gas chlorinator system that separated the ejector from the vacuum regulating and chlorine flow metering components. Recognizing the relative insolubility of chlorine in water, it is possible to eliminate two very serious problems that occur with all chlorinators that either incorporate their ejector in a floor cabinet or mount them as an integral part of a wall-mounted system, or where the remote ejector is mounted some distance from the actual point of chlorine application. First, we have essentially eliminated corrosion of pipes, valves, etc. in the system being treated and, second we’ve eliminated hazardous solution lines which contain a very corrosive liquid and a large quantity of chlorine gas under pressure. Both of these problems have been eliminated simply by locating the ejector directly at the diffuser where the resulting chlorine solution will be injected into the water or wastewater being treated. In the REGAL system, the chlorine gas is conducted from the chlorinator to the point of diffusion through a vacuum line. The gas is never above atmospheric pressure in this line. At the ejector the chlorine gas is mixed with water (at vacuum conditions) and immediately injected into the treated system through a diffuser. The chlorine that has not been dissolved in the water is in the form of thousands of almost microscopic bubbles which, when entering the much larger flow of the main stream, is immediately dissolved. However, if the solution discharging from an ejector is conducted to the diffuser through a chlorine solution line, the very fine bubbles rapidly grow together (coalesce) into larger bubbles and these larger bubbles contain chlorine, moisture and air, which do not quickly dissolve into the main stream after leaving the diffuser. These larger bubbles travel along the top of the pipe, or collect in high points to cause severe corrosion in the system being treated. Injection into the suction-side of pumps has often met with strong objection because of severe corrosion that has occurred to the pump impellers and other parts. With the REGAL ejector, close coupled to the diffuser at the point of solution injection into the suction-side of the pump, we have not experienced this problem. However, with solution lines as short as 810 feet (3 meters) you can have bubbles ranging from 1/8” to 1/4” (0.3 to 0.64 cm) in size. A 30’ to 40’ (9 to 12 meters) length of solution line gives time to form bubbles 1/2” to 3/4” (1.2 to 1.9 cm) in diameter. In addition, the formation of these larger bubbles in the solution lines themselves, often creates a serious erosion along the top of the pipe or hose. This ultimately creates a weak spot in the solution line where breakage or rupture can occur. This is not an uncommon occurrence. Regulatory agencies and users often insist that the chlorinator and cylinders be isolated in a separate room. This is a good idea. However, there has been little or no concern about the fact that a solution line from the chlorinator ejector is carried outside the room – possible through a public area or through an area containing critical equipment – and it may not even be protected from any physical damage by some type of conduit. These solution lines are always under pressure and since they contain a highly corrosive solution and undissolved chlorine gas, these lines should be considered as chlorine gas pressure lines. In addition, if a “solution line” is cut or damaged, the chlorine gas will continue to escape into the area and strong, corrosive chlorine solution will also escape. The chlorinator has no way of detecting this situation, and it will continue to operate. When you consider this fact, and the fact that as much as half of the chlorine which has gone through the chlorinator may still be in the form of gas, you can realize the hazard of chlorine solution lines. We have seen countless numbers of cases where no concern is given to a long length of unprotected solution line, but there is great concern that the chlorine gas vacuum line be enclosed in a separate, sealed protective conduit. If the vacuum tubing between the chlorinator and the ejector should be cut, air immediately enters the cut in both directions and the chlorinator inlet safety valve closes tight at the cylinder. Visualize a piece of vacuum tubing from our ejector passing through a room and also a solution line in a second chlorinator passing through that same room. Cut the vacuum tubing and the chlorinator would shut off. You could possibly detect a faint odor of chlorine, but this is doubtful. However, cut the solution line and you will not only get sprayed with a strong corrosive and irritating solution, but it will probably be impossible for you to remain in the room for more than 15 or 20 seconds due to heavy concentration of chlorine gas. AVOID SOLUTION LINES WHEREVER POSSIBLE! Hydraulic Considerations Involving Chlorine Solution Lines Another drawback to solution lines, particularly long pipe runs, is the likelihood that this will force the use of a larger booster pump than would be necessary if the ejector is installed directly at the application point. Two distinct situations usually exist: 1. It is required, for some reason, that the booster pump be located near the chlorination equipment, or 2. It is not important where the booster pump is located. In the first case, where the booster pump is located near the chlorination equipment and some distance (for example 100 ft or 30 meters) from the application point, we have to calculate the friction losses incurred in the piping, since they can be quite significant. For purposes of this discussion we can ignore friction losses in the booster pump suction piping since it would be essentially the same whether the ejector is located very close to the booster pump with a ‘solution’ line running to the application point, or the ejector is installed right at the application point. Assume a chlorine feed rate of 50 ppd (1000g/hr.) and a backpressure at the application point of 60 psig (4.21 kg/cm2), and a standard REGAL ejector nozzle No. 17A. Back Pressure 60 psig (4.21 kg/cm2) 71 psig (5.0 kg/cm2) Ejector Supply Pressure Required 109 (7.66) 131 (9.21) GPM (1/Sec) 18.5 (1.17) 20.0 (1.26) Friction loss in 100 ft. (30 m) 1” SCH. 80 PVC = 11 PSIG (.77 kg/cm2) A. With Solution Line: Add the friction loss of 100’ (30 m) of the pipe to the backpressure. This gives you an effective backpressure of approximately 71 psig (5.0 kg/cm2). The ejector supply pressure must be at least 131 psig (9.21 kg/cm2). Therefore, the booster pump must raise the suction pressure (assume 60 psig or 4.21 kg/cm2) at least 71 psig (5.0 kg/cm2). B. Remote Ejector At Application Point: Add the friction loss of 100’ (30 m) of pipe to the ejector supply pressure required (this is the amount of pressure loss between the booster pump and ejector inlet). The backpressure is 60 psig (4.21 kg/cm2), the same pressure as the water to be treated at the application point. The ejector supply pressure required for the back pressure is 109 psig (7.66 kg/cm2), but we add the 11 psig (.77 kg/cm2) friction loss, so the effective booster pump outlet pressure must be at least 120 psig (8.44 kg/cm2). Therefore the booster pump must raise the suction pressure at least 60 psig (4.21 kg/cm2). In the above example you can see that the use of a chlorine solution line instead of ejector installation right at the application point, results in a net increased booster pump requirement of 11 psig (0.77 kg/cm2). In the actual practice, this difference would be greater due to increased ejector water flow requirements at the higher backpressure, which itself creates additional friction loss, and so forth. The alternative is to increase the solution pipe diameter (at significant cost increase) to reduce friction losses. The second case, mentioned earlier, presents the ideal answer. Wherever possible, locate the booster pump and ejector in the same area as the point of chlorine application, and just run chlorine vacuum tubing to the ejector from the chlorinator. This eliminates friction loss problems, eliminates dangerous chlorine solution lines, and reduces the required booster pump size significantly. In the same application example as above, the booster pump would only have to raise the suction pressure by 49 psig (3.44 kg/cm2). Of course, both of the “first case” examples ignored any friction losses in the booster pump suction piping, which would have to be added to the “boost” requirements. For practicality, economy and safety, place the gas chlorinator ejector as close as possible to the chlorine application point. chlorinators incorporated 1044 S.E.

No. 1106-2 TECHNICAL BULLETIN 7609-1 September 1, 1976 Revised – 3 July 2006 SIZING GUIDE FOR REGAL GAS CHLORINATORS The basic formulas for determining the proper gas chlorinator size is based on the maximum expected flow rate of water or wastewater at any time and are as follows: lbs./day chlorine - (0.012) X (flow rate in US gpm) X (dosage in ppm) lbs./day chlorine - (0.015) X (flow rate in IMP. gpm) X (dosage in ppm) gms./hr. chlorine - (3.6) X (flow rate in 1/s) X (dosage in mg/1). Example: A deepwell treatment station is pumping drinking water at a maximum rate of 1000 gpm. Water quality is good with low chlorine demand and requires a chlorine dosage rate of 2 ppm to maintain required chlorine residual: lbs./day = .012 X gpm X ppm lbs./day = .012 X gpm X 2 lbs./day = 24 Allowing for an oversizing safety factor of at least twice the required dosage rate, a 50 PPD REGAL Gas Chlorinator is used. __________________________ Abbreviations ppm - parts per million (by weight e.g. pounds per million pounds) mg/1 - milligrams per liter (numerically equal to ppm) gpm - gallons per minute 1/s - liters per second PPD - pounds per day (chlorine feed rate) gms./hr. - grams per hour (chlorine feed rate) Definition of terms used in chlorination of water and wastewater: B.O.D.: Biochemical oxygen demand: oxygen required for the biological and chemical oxidation of substances contained in water or wastewater within a specific amount of time under specific conditions. Demand: The amount of chlorine needed to satisfy reducing substances present such as organic matter, manganese, unoxidized iron, sulfides, etc. Dosage: Amount of chlorine, expressed in ppm or mg/1, which must be injected into water or wastewater to satisfy the demand and maintain a required chlorine residual. Residual: Chlorine remaining, after a specific contact time, which is still available for reaction. Essentially, this is the amount of chlorine in excess of the DEMAND. Free Chlorine Residual: That portion of the total chlorine residual that remains in the water or wastewater, at the end of a specified contact period, which will react chemically and biologically as hypochlorous acid or hypochlorite ion. -2Combined Chlorine Residual: The portion of total chlorine residual that remains in the water (or wastewater), at the end of a specific contact period, which will react chemically and biologically as chloramines.

One of these misconceptions is you can only withdraw 40 to 50 pounds of chlorine per 24 hours from a single chlorine cylinder. The actual basis for this idea goes back many years to the time when the only type of gas chlorinator available was either mounted on a wall or in a floor cabinet. These units were connected to either the chlorine cylinder or to a manifold by means of flexible connectors. Users of these gas chlorinators were told to connect one (1) 100-pound or 150-pound cylinder of chlorine to the chlorinator or chlorinator manifold for each 40 or 50 pounds per 24 hours of chlorinator feed rate capacity. At that time, all manufacturers of gas chlorinators had the same problems. Liquid chlorine could and would be formed in the copper flexible connectors, and in the steel manifolds. There were already so many points of potential pressure leakage that it really didn’t make much difference if one or more additional cylinders were hooked up. At the time when the concept of mounting the chlorinator directly onto the chlorine cylinder valve was introduced, maximum withdrawal rates suddenly became important. The idea that only 40 to 50 pounds per 24 hours could be continuously withdrawn from a single cylinder was pushed very strongly by gas chlorinator manufacturers who, at that time, did not have a direct-cylinder mounted gas chlorinator to offer. Users were told that when chlorine was withdrawn above these rates the chlorine would freeze; the valves would freeze up; the chlorinator would stop working; liquid would be formed in the chlorinator; etc. This issue was pushed very strongly in the 1960s and consequently remains in the minds of many people today. The primary facts stressed at that time seemed to indicate that the Chlorine Institute clearly states that only the low withdrawal rates are possible. Many people today will still steadfastly maintain that the Chlorine Manual, published by the Chlorine Institute, contains a statement to this effect. In actuality, the Chlorine Manual clearly spells out the findings of the Chlorine Institute with regard to chlorine withdrawal rates. It states, first, that the dependable continuous discharge rate of gas from a single 100 or 150 pound cylinder is about 1 ¾ pounds per hour, which is about 42 pounds per day. This, however, is stated to be under the conditions of 70°F when discharged against a back pressure of 35 psi and without the cylinder sweating on the outside. These findings also indicate that if sweating can be tolerated, these rates can be doubled. This takes us up to 84 pounds per day. It makes little difference to anyone whether or not the outside of the cylinder has sweat or condensation on it, and it certainly has no effect on the operation of the chlorinator. The item that is most often overlooked is the fact that this data is given for discharging against a 35 psi back pressure. With a vacuum operated, solution-feed gas chlorinator mounted directly onto the chlorine cylinder valve, the discharge is not against a positive pressure, but is actually against a controlled negative pressure of about 2 psi below atmosphere. To further verify this, data was obtained from tests made by one of the leading chlorine producers which showed a continuous withdrawal rate of above 125 pounds per day. They were discharging against 0 (atmospheric) pressure. Additional tests were conducted during the winter and a 100pound chlorine cylinder was placed out-of-doors at 20°F and left out-of-doors several days. At the time this test was conducted, the actual liquid chlorine temperature was 20°F. A 100 PPD chlorinator was connected to the cylinder valve and operated at above 100 PPD continuously. Higher than maximum capacity was withdrawn until the liquid was almost exhausted, at which time the rate dropped to about 60 pounds per day for only a few minutes until the chlorine cylinder was empty. Figure 1 illustrates the rate of chlorine discharge in pounds per day from a 150-pound cylinder, at 70°F, into the atmosphere (no back pressure) over a period of 20 hours. Curve “A” shows the rate of chlorine discharge over any given period of time when air is circulated by a fan blowing against the cylinder. Note that in this case maximum chlorine discharge rates are continuously maintained at over 200 pounds per day and that the entire cylinder was exhausted in just 8 hours. However, more normal conditions are represented by Curve “B” where no air is circulated past the cylinder by a fan. Curve “B” illustrates the fact that at least 100 pounds per day of chlorine can be discharged continuously against a 0 psi back pressure. In fact, the entire 150 pounds of chlorine contained in the cylinder would be exhausted in just 20 hours at 70°F. Figure 2 illustrates the same data as above but it is expressed in terms of the total pounds of chlorine which are discharged over a given elapsed time, with the same conditions as stated for Figure 1. It should be noted that in the case where air is not circulated against the cylinder by a fan, as in Curve “B”, 100 pounds of chlorine will be discharged in less than 9 hours. Another misconception that has managed to survive after all of these years is the story that if chlorine is withdrawn at too high a rate from a single cylinder, the chlorine will freeze. This is impossible. Chlorine freezes at approximately -150°F. The pressure in the cylinder changes only with the temperature change and has nothing to do with the amount of liquid left in the cylinder. A certain lack of understanding on this point has led many people to believe that a chlorine pressure gauge installed in the system will somehow let them know how much chlorine remains in the cylinder. The vapor pressure curve presented in the Chlorine Manual shows that the cylinder pressure at 80°F is 102 psi. At 60°F the pressure is 71 psi at -30°F the pressure in the cylinder finally drops to 0 psi. A direct-cylinder mounted gas chlorinator will actually draw about a 2 pound vacuum in the cylinder. As gas is taken out of the cylinder the pressure in the cylinder is reduced which causes the liquid in the cylinder to boil. This boiling obviously requires heat which is supplied by the temperature of the air around the cylinder. At high withdrawal rates the temperature of the outside of the cylinder adjacent to the chlorine liquid surface is lowered and this will eventually cause condensation of moisture to form on the outside of the cylinder. At very high withdrawal rates the temperature at this surface may drop below 32°F and the condensation will freeze to form a frost layer. This is the same thing that can happen in valves, flexible connectors or manifolds where the chlorine gas has gone back to liquid state and is then rapidly re-evaporated. Obviously there is no freezing on the inside and the frost is merely an indication of the outside surface temperature and high humidity. This is no different than frost forming on refrigerator coils and certainly the refrigerant inside the coils is not frozen. An examination of the chlorine vapor pressure curve, shows that as the temperature of the liquid—and consequently, the pressure—becomes lower and lower you finally reach an equilibrium condition. At this point, the amount of gas that can be withdrawn from the cylinder is strictly a function of how much heat can be supplied from the atmosphere. Since the withdrawal rate is now limited, the cooling effect due to evaporation remains constant. Let us examine for a minute the condition that exists when a gas chlorinator is hooked up to a cylinder by means of a flexible connector. The pressure inside the chlorine cylinder, the flexible connector, and in the gas manifold is constant since the cylinder valve is open and there are no points of pressure reduction. The cylinder itself is essentially a boiler with a very heavy steel wall. The flexible connector is comparable to a condenser tube with the surrounding air being the cooling medium. Since this system contains both liquid and gas phase, any decrease in temperature will cause some of the gas to go back to liquid. What often occurs is that a door or window is opened to cool off the room, or thunderstorm or other change in weather causes the room to cool. Even sun through a window hitting the cylinder, but not hitting the flexible connector, can cause the connector to be at a lower temperature. Any slight differential in temperature that occurs will cause gas in the flexible connector and manifold to change to liquid. This liquid passing through the lines will actually tend to scrub the copper and steel so that when the liquid re-evaporates, dirt will be deposited. This remains the greatest single source of chlorinator failure and maintenance in noncylinder mounted gas chlorinators. All chlorinator systems having flexible connectors and manifolds should either be in a temperature controlled room or have special heaters on the connectors and manifold to make sure that they are at all times at a higher temperature than the cylinder. A direct-cylinder mounted gas chlorinator is not susceptible to this problem since cylinder pressure is immediately reduced to a vacuum as the gas leaves the cylinder valve and enters the chlorinator, imparting what is known as “superheat” to the gas, making condensation of the gas back into a liquid a physical impossibility.
