Thermostat Heating Cooling Circulator for Glass Reactor

The thermostat heating cooling circulator is suitable for glass reactors, metal reactors and bioreactors to control the rise and fall of temperature as well as constant temperature. In the chemical and pharmaceutical fields, thermostat heating circulators often perform the necessary temperature control together with the chemical reaction of the material itself. Through the temperature change of the circulating medium in the sheath or coil, the temperature control of the material and the target process temperature of the material can be achieved.

For the temperature control of thermostat heating cooling circulator in the pharmaceutical industry, the requirements for selecting temperature control equipment are relatively high. It requires a wider operating temperature range than the ordinary temperature range -80℃-200℃. At the same time, different chemical reactions require different temperature profiles, and high-temperature and low-temperature integrated units need to work at any different temperature points within this temperature range.

We know that some substances in chemical reactions are exothermic and some substances are endothermic. The temperature control unit needs to be able to cool and heat over the entire temperature range. In order to ensure the accuracy and stability of temperature control, it is also necessary to dynamically respond to different set target temperatures. Therefore, the requirements for the equipment are fast response speed, fast temperature switching and rapid achievement of the target temperature.

The thermostat heating cooling circulator’s temperature-controlled high and low temperature integrated device uses electric heating, which can quickly increase the temperature of the circulating medium. Adopting an energy-saving design, it can adjust the cooling capacity and control the material temperature. The material can absorb heat or respond quickly to heat release, thus meeting the production needs of most industrial occasions.

The characteristics of thermostat heating cooling circulator are as follows:

(1) The control of material temperature is mainly achieved by controlling the refrigerant flow. The refrigerant proportional control valve uses the valve body of an electronic expansion valve. Can achieve higher temperature control accuracy;

(2) The temperature of the cascade compression refrigeration cycle of the refrigeration unit can be reduced; electric heating is used to quickly increase the temperature of the circulating medium;

(3) Adjustment of cooling capacity is achieved. The refrigerant flow is mainly controlled by PID, and the material temperature is controlled. The traditional method is to use electric heating to offset the cooling of the compressor, which wastes energy.

(4) The combined control of heating and cooling enables rapid response to the heat absorbed or released by the material;

The temperature control system of the thermostat heating cooling circulator consists of a refrigeration cycle system, a heating cycle system and an automatic control system. For areas with explosion-proof requirements, positive pressure explosion-proof cabinets can be customized, which not only meet the explosion-proof requirements, but also reduce the number of explosion-proof components and reduce the production cost of the entire machine.
