WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD. ♦ Working temperature range from -25°C to 200°C, other temperature range need to set to the widest temperature range (-50°C to 250°C) ♦ Centralized control of 2~20 reactors, each reactor's material temperature and jacket temperature can be set independently. One system control multiple reactors of target temperature is realized. ♦ Maximum process stability and reproducibility. ♦ Under the system control, energy-saving efficiency is improved.The freezing medium and heating medium flowing through the conduction angle of the reactors are controlled accurately. ♦ Previously unachievable performance. ♦ High-accuracy and intelligent temperature control. ♦ Adopt Plate heat exchanger & Piping heater to improve the heating and cooling rates. Temperature control system for many pilot and industrial production reactors Advantages & Functions ♦ Ultra-high temperature flexible cooling technology, the process that using cooling water to cool down from 250°C will not produce steam. Temperature rise of water temperature is controlled within 40 degree and it can reduce fouling risk of heat exchanger. ♦ Factory's existing refrigeration system and heating system can be used together with this system in order to reduce the input cost. ♦ Large temperature range without fluid change. ♦ Increased thermal fluid life. ♦ 10 inch TFT touchscreen with graphic display. ♦ Comprehensive warning and safety functions. ♦ Superior performance and unique. ♦ With USB interfaces, RS485 interfaces, industrial control configuration software. ♦ It can be produced explosion-proof function according to customer's requirement. Structure Design The whole system we adopt is fully closed piping design, high efficiency plate heat exchanger used to reduce the demand of thermal fluid as well as greatly increase utilization of heat in order to achieve rapid ups and downs in temperature. The system with an expansion vessel, and the heat-conducting medium in the expansion vessel does not participate in liquid circulation, whatever the temperature is high temperature or low temperature, the expansion tank is limited to 60°C. The working life and properties of the thermal fluid are also protected, by avoiding direct contact between the hot fluid and atmosphere. There following advantages for the users: ♦ Volume changes due to fluid temperature fluctuations are equalised by the expansion vessel. The fluid in the expansion vessel hydraulically seals the fluid circuit and prevents early Oxidation. ♦ No volatilization of heat conducting medium at high temperature. ♦ No need to change the heat-conducting medium, meantime, continuous control of the temperature of the below range can be achieved without any pressure: -55°C ~ 250°C. One system can control up to 2~20 sets different sizes of reactors and each reactors can be controlled at different temperature. Energy Saving Design Under the system control, the freezing medium and heating medium flowing through the conduction angle of the reactors are controlled accurately. Energy-saving is maximized. The temperature feedback points of each reactor are almost consistent. A. The whole system we adopt is fully closed piping design,high efficiency plate heat exchanger used to reduce the demand of thermal fluid as well as greatly increase utilization of heat in order to achieve rapid ups and downs in temperature. B. The system with an expansion vessel, and the heat-conducting medium in the expansion vessel does not participate in liquid circulation. C. The expansion tank with automatic cooling constant temperature system, eventhough the temperature of heat conducting medium up to 2S0°C, some part of heat medium run to expansion tank carried away to keep the expansion tank always at room temperature, which can reduce the heat conducting medium absorb water and volatilize, oxidative to improve the medium lifetime. The coolant temperature control system model can also be applied to the pure cooling refrigeration system, just press the reverse direction control button in the electrical control panel. (The program has been provided with the pure refrigerant refrigeration control program) If the material collected and setting temperature is used by 4~20mA or 0-10V signals, be defined as -50~250°C A system with larger heat transfer area can be designed according to requirements
