teco – Range of temperature controllers Choosing the right temperature controller – Water/oil – direct/indirect cooling For over 40 years – Perfect cooling and temperature control For over 40 years Gesellschaft Wärme Kältetechnik mbH has been manufacturing high-quality temperature control and cooling equipment and supplying this equipment worldwide. Today more than 400 employees design, produce and install complete process solutions for heating and cooling in customer specific designs. More than 33 sales and service locations worldwide represent the global character of our work and guarantee our permanent success. Headquarters in Meinerzhagen, Germany 2 In addition to a huge product range of serial products we also offer tailor-made solutions for challenging applications. These individually designed units are available for a temperature range between –40 °C and +400 °C, and are developed and produced in Meinerzhagen according to the customers’ demands. As one-stop manufacturer of compact units, cooling plants and temperature control units, up to water treatment and heat recovery systems and complete container systems, gwk is a competent and innovative partner. The production In the modern production facilities not only standard temperature controllers, but also customized and process-specific solutions are developed and manufactured. A large number of patents and utility patterns testify for the innovative strength of the gwk engineers and technicians. International success achieved by innovative temperature control Temperature control has a decisive influence on the quality and the economic efficiency of industrial processes. The highest possible productivity is required to be successful among international competitors. Here you have to count on partners, who not only know the processes, who analyse and optimize them, but also dispose of sufficient experience in international business as well as of a global presence at the same time. gwk made a name for itself as a world-wide specialist for high-quality temperature controllers, temperature machines and complete temperature control systems. All around the world in the plastic, automotive, food, chemical and cosmetic industry specialists count on our temperature control systems in order to optimize their products. Perfect Cooling and Temperature Control 3 www.gwk.com Process-optimized temperature control Customer-specific and process-optimized heating and cooling technology – on a mass production basis Each production process requires control that is exactly matched to it individually. Only in this way is it possible to achieve optimum results in terms of quality and economy of operation. The number of different processes determines the large number of temperature controllers to be designed and manufactured. A number of customer-specific wishes can be incorporated into the design and the ability to be integrated into the processing machines, as well as coping with countryspecific forms of configuration. This requires a great deal of experience and well proven designs that nonetheless allow a great deal of latitude for incorporating the wishes of individual customers, and it also implies well organised and extremely flexible production methods to meet all these requirements within the generally short delivery times without in any way compromising the quality of the finished product. We at gwk can meet all of the above prerequisites. The choice of a particular technical process starts with the sales process. There gwk has a team with many years of experience in the most varied forms of user applications from all branches. Depending on the overall configuration of the temperature controller, the order is either sent on directly to the production section or else is passed on to the technical departments for further work. The very latest CAD technology and a high level of standardisation mean that even the most technically demanding specifications 4 can be handled within a short time. Mass production units, to some extent modular, are produced from individual configuration variations. Our production capabilities help in implementation in actual instances. Facilities within the company for sheet metal processing, the construction of switch cabinets, a production centre for the machining of mechanical parts and modern pipe bending and welding units not only ensure consistently high quality but simultaneously reduce the throughput times. Nonetheless, our technical staff are of even greater importance, and we are justifiably proud of them. Many of our specialists have been trained by us all by ourselves. Thus the average age of our work force is relatively low despite considerable experience in technical areas – thus providing a strong potential capability for the future, and one which our customers value. Since we are a recognised welding operation, our certified welders can produce pressure vessels up to a nominal rated pressure of 100 bar. This makes us specialists in pressurised hot water temperature controllers for circulating temperat ures of up to 200 °C. Our international know-how allows us to produce machines and equipment to virtually all the standards required on the world market. As part of this, our comprehensive, certified quality management system guarantees monitoring of all production steps.

Direct cooling is an advantage, when a high cooling capacity is required at low temperature differences between cooling water and the circulation medium. In this case the cooling water will be fed without temperature loss into the circulation circuit. The water circuit, designed as a closed system, allows a pressurized use up to 150 °C. Depending on the operating condition, the heat will either be removed from the consumer by cooling or transferred to the consumer by heating. The heat transfer occurs by the circulation medium water which is to be transferred with an efficient pump through the consumer. Control of the circulation medium temperature takes effect automatically. A temperature sensor, installed inside the unit, measures the existing actual temperature. The microprocessor controller compares the measured value with the adjusted set value and switches the heating or cooling accordingly. A trouble-free operation is guaranteed by a comprehensive safety system. 12 As standard the unit is equipped with a large number of functions, on request this may be complimented by various useful options. For connection with the controllers of the processing machines all current interfaces are available. • Self-optimizing microcontroller with high control accuracy • Simultaneous display of set and actual values • Measuring, indication and monitoring of the flow rate • Integrated operating and service information • Storage and recall of process parameters with memory card • Wearless, energy-saving solid state heating control • Continuous monitoring of process parameters • Splash proof electrics • Optional connection for external thermocouple (Fe-CuNi or Pt 100) • Optional interfaces (analog 0 - 10 V, 0/4 - 20 mA; serial RS 232, RS 422, RS 485, TTY; CAN-Bus; Profibus; Varan-Bus) • Covers: RAL 2004 pure orange • Front panel and housing: RAL 7035 light grey The temperature controllers of the series teco wd with their modular design cover a large range of applications with a high range of performance.

In order to be able to transfer a constant amount of heat between the mould wall and the medium for the same median temperature differential, four to five times the area of cooling surfaces, or the same number of cooling channels, is required if heat transfer oil is used instead of water. It is precisely this which often cannot be achieved in practice with small moulds. The use of water as a heat transfer medium has the further advantage that the amount of liquid to be circulated by the pump is reduced by a factor of two to three compared with heat transfer oil. The gwk hot water temperature controllers of the teco wh series are designed for special applications in the temperature range up to 200 °C. Magnetically -coupled pumps, return flow temperature monitoring and limiting, a built-in condensing unit to prevent steam impacts, level monitoring via a built-in high-pressure makeup feed unit and a ramp function included as standard for temperature changes to heat up the mould more gently at the start of production and the corresponding cooling down at the end of production guarantee the highest possible level of process security. The modular construction of the heating and cooling sections allows a unit to be designed for any type of application.

Dealing with thermal oil makes it necessary to take different criteria into account which also have a constructive influence on the design of oil temperature controllers. Hot thermal oil has a low oxidation stability when direct contact to ambient air is allowed as found in some competitors units which use a submersible pump and tank. This increase of air absorption can cause the oil to become more viscous and the pump flow rate to decrease. As an open design does not allow for a defined flow with reliable monitoring this oxidation due to the lowering flow rate can cause an excess of oil film at high temperature on the heating element which will lead to a tarry coating and carbon deposits forming within the heat transfer system eventually leading to the decomposition of the oil and subsequent clogging of the heat transfer system. The consequence of choosing the wrong type of oil temperature controller are more waste product, poor product quality and higher maintenance costs. It is due to these reasons that gwk do not manufacture oil temperature controllers with an open circuit. The gwk teco to, teco tt and th series have been specially designed for applications that require higher temperatures. The specific heating surface loading is designed to be such that thermal decomposition of the heat transfer oil can be prevented without fail at normal flow rates. Built-in flow monitoring ensures that an alarm is given if t h e f l o w r a t e b e c o m e s t o o l o w. I t i s necessary to prevent oxygen from entering the system in order to avoid damage to the heat transfer oil from oxidation.
