ENGINEERING DATA - DIMENSIONS 420.10-SED1 (JUN 07) Page 3 IMC Line of Cooling Towers The IMC series optimizes an induced draft counterflow design. Factory and field tests have proven that this is the most efficient design for cooling tower performance. Thus, the IMC’s enhanced performance yields lower operating costs; a tangible benefit for owners and operators. The IMC series typically uses up to one third less plan area than a competitive crossflow tower of comparable capacity. Significant savings in structural support can be realized due to the related reduction (up to one third less) in cooling tower weight. The IMC series is designed for air conditioning and industrial water cooling applications in a variety of climatic conditions. The IMC is a heavy-duty cooling tower. All of its major components, fans, inlets, motors, fill, nozzles, bearings, and gearboxes have been selected and built to ensure efficient and dependable service for years of trouble-free service. Hot Dip Galvanizing Imeco stands alone in providing a hot dip galvanized after fabrication basin as standard on every cooling tower we build. We have "twice the thickness" zinc protection compared to competitors G235 “mill galvanized before fabrication” offerings. Our hot dip galvanizing after fabrication process ensures the longevity and durability of your cooling tower installation. ® 800 series Our "twice the thickness" zinc also protects the holes and the sheet metal edges created by tower panel fabrication. Our metal doesn't deteriorate like the “painted holes and edges” inherent in the standard G235 “mill galvanized before fabrication” construction offered by others. As has been graphically recorded by the American Galvanizers Association, "twice the zinc" thickness directly corresponds to twice the corrosion protection, yielding dramatic increases in cooling tower longevity. Hot dip galvanized after fabrication tower panels are a prudent investment in the life of your cooling tower. Reliable Year-Round Operation The IMC series cooling tower is well suited for winter operation. The induced draft counterflow design encases the wet fill section, isolating it from freezing winds. This inhibits ice formation in the fill and minimizes performance degradation. It all but eliminates fill collapse. The basin’s internal bracing minimizes splashing that can cause inlet louver freezing. Competitive crossflow designs have a tendency to form ice along the inlet louvers and fill during cold weather operation. The buildup of ice reduces the unit’s thermal capacity and can cause costly damage to the fill and louvers. Imeco's pressurized spray system allows customization of our towers for use in Free Cooling Systems. The spray pattern can be tailored for a specific climatic condition or is capable of a large variation in flow rates needed for seasonal changes. Please contact your local Imeco representative for your specific application. ® 420.10-SED1 (JUN 07) Page 4 COOLING TOWERS SPECIFICATIONS - ENGINEERING DATA - DIMENSIONS Low Air Intake and Vertical Air Discharge The low air intake and vertical discharge of the IMC series reduces the chances of air recirculation because the warm, humid discharge air is directed away from the unit’s inlet. The distance between inlet and discharge on an IMC is greater than for a comparable crossflow tower. This distance further minimizes the potential for performance problems associated with discharge air recirculation. discharge air and allows only 0.002% of the recirculating water to carry over. In areas where minimal water carryover is critical, Imeco offers an optional system that has a drift rate of 0.001%. ® The standard drift eliminator material is polyvinyl chloride (PVC). This is an inert plastic and is corrosion resistant to cooling tower environments and water treatments. For applications in very hot climates such as a desert, the optional high-temperature (HPVC) eliminators can be used. The drift eliminator sections are easily removable for inspection of the water distribution system and fill section. Cooling Tower Fill The IMC series uses a heavy-duty fill constructed from an inert plastic material. The fill is designed to produce multiple surfaces for water filming to occur and provide a highly turbulent mixing environment for the air and water. This enhances water cooling by maximizing latent and sensible heat transfer from the water to the air stream. The fill is constructed from crossfluted sheets bonded together. This construction produces a strong enough structure that, with care, can be used as a working platform. Efficient Drift Eliminators The IMC series has an extremely efficient and cost effective drift eliminator system. The standard, patented threepass design removes entrained water droplets from the The standard fill is constructed from PVC and will withstand continuous water temperatures of 135°F. An optional hightemperature fill is available for temperatures up to 150°F. The fire-resistant qualities of the fill are excellent. In tests conducted in accordance with ASTM-E84-81a, its flame spread rating was 5. The flame spread rating scale ranges from 0 (noncombustible) to 100 (highly combustible). COOLING TOWERS SPECIFICATIONS - ENGINEERING DATA - DIMENSIONS Water Distribution System Belt Drive System The water distribution system is constructed from schedule 40 PVC pipe, rubber connection couplings, and polymer spray nozzles. The piping is easily removable for cleaning. The IMC 1200 series spray header has a removable cover plate opposite the inlet connection that allows the main distribution header to be thoroughly cleaned. The standard spray nozzles have a minimum opening width of 3/8 inch, for maximum resistance to clogging. Aluminum Alloy Sheaves 420.10-SED1 (JUN 07) Page 5 The drive system sheaves that are located inside the cooling tower are constructed of a corrosion resistant aluminum alloy. The aluminum sheave is superior to steel or cast iron due to its light weight and corrosion resistance. It is also superior to competitive nylon sheaves which absorb water and tend to shrink and crack over time in cooling tower applications. The nozzle system provides an even water pattern over the fill, ensuring optimal thermal performance. The pattern is stable over an extremely wide range of flow rates. This stable pattern allows IMC series cooling towers to be customized for Free Cooling or for customer specific climatic conditions. This system is ideal for cold weather applications. Air Circulation System Corrosion resistant aluminum axial fans are used to circulate air through the IMC series cooling towers. The 1200 series fans are powered by specially built motors that are VFD (variable frequency drive) ready and have a unique five-year warranty. The IMC standard fan drive features optimized banded belts and custom built bearings. An optional gearbox drive is also available. Power Bands The power band belt is a banded multigroove belt constructed from premium quality rubber compounds using tough synthetic cords. This is the most efficient type of belt for cooling tower applications. For extended life, the belt is sized as a minimum, for 150% of the motor nameplate horsepower. 420.10-SED1 (JUN 07) Page 6 COOLING TOWERS SPECIFICATIONS - ENGINEERING DATA - DIMENSIONS Belt Drive System Fan Motors IMC 800 Series The fan motor is VFD ready and totally enclosed fan cooled (TEFC) with a service factor of 1.15 and suitable for cooling tower use. The motor is mounted outside of the tower on a steel frame that is hot dip galvanized after fabrication for maximum corrosion protection. Motor inspection and belt adjustment are easily accomplished from the outside. A removable hood shields the motor and sheave from the weather. Multispeed motors and premium efficiency inverter-duty motors are available to meet your capacity control needs. IMC 1200 Series The standard fan motor is totally enclosed with a service factor of 1.15 built exclusively to Imeco’s specifications for use in our cooling towers. The motor is VFD ready. The motor is environmentally sealed to prevent contaminants and moisture from entering the casing. Imeco’s specially designed motor drains and vents ensure that moisture will be purged from the motor to extend useful life. Imeco motors are guaranteed for five years mechanically and electrically in non-VFD applications. When used with a VFD, the motor is guaranteed for three years electrically and five years mechanically. ® Optional multispeed motors suitable for cooling tower applications are offered as an alternative means to meet your capacity control needs. Fan Shaft Bearings IMC 800 Series The bearing races are specially treated and additional seals are added for cooling tower application. This provides a long, trouble-free life. Lubrication lines are extended to the casing for easy maintenance from outside the tower. IMC 1200 Series The fan shaft bearings are flange-mounted, self-aligning roller bearings with a five-year warranty. The bearing is specially built to an Imeco specification for use inside a cooling tower. The flange mount is superior in design to the standard pillow block for the high thrust loads that occur with the use of large diameter axial fans. This bearing has a minimum L10 of 133,500 hours, 78% greater than the competition. ® Lubrication lines are extended through the casing for easy maintenance from outside the tower. Imeco offers a five-year warranty on its 1200 series fan shaft bearings. ® Inlet Louver Design The air inlet louvers are constructed of corrosion-free PVC. They have a two-pass design that eliminates splashout and inhibits algae growth inside the tower basin. This design also has a low pressure drop, minimizing fan energy consumption. COOLING TOWERS SPECIFICATIONS - ENGINEERING DATA - DIMENSIONS 420.10-SED1 (JUN 07) Page 7 Inspection and Maintenance Accessibility The basin is open and accessible from ground level by simply removing a section of inlet louver. There is a depressed section of the basin designed to accumulate solid impurities. These impurities are easily flushed out through the drain with a hose. A large access door is provided in the fan section for access to the drift eliminators, fill, spray system, and fan drive components. Optional handrails on the top of the unit can be provided upon request. Gearbox Drive System (Optional) Gearbox A gearbox designed for use in cooling towers is an option on all models. The gearbox is coupled to a motor; motor has a 1.15 service factor. An oil level sight glass is provided on the outside of the unit for easy inspection. Heaters and Thermostats (Optional) Electric immersion heaters are available factory installed in the basin of the tower. They are sized to maintain a +42°F pan water temperature with the fans off at several outdoor ambient temperatures and a 45 mph wind. They are furnished with a NEMA 4 thermostat to cycle the heater on when required. A NEMA 4 cutoff switch is included to prevent the control from energizing the heater elements unless they are completely submerged. The heater power contactors and electric wiring are not included as standard. (See chart below.)
