The reactor is equipped with a cooling and heating machine to achieve refrigeration and heating through one equipment, which is suitable for glass reactors, metal reactors and bioreactors in the chemical and pharmaceutical industries for temperature rise and fall and constant temperature control.
In the chemical and pharmaceutical fields, the reactor is equipped with a cooling and heating machine, which usually carries out the necessary temperature control together with the chemical reaction of the material itself. The reactor is equipped with an integrated cooling and heating machine with electric heating, which can quickly increase the temperature of the circulating medium. The energy-saving design realizes the adjustment of the cooling capacity and can accurately control the temperature of the material.
The characteristics of the reactor supporting the cooling and heating machine are as follows:
2. The adjustment of the change of refrigeration capacity has been realized. The refrigerant flow is mainly controlled by PID, and the material temperature is accurately controlled, the traditional method uses electric heating to offset the cooling of the compressor, which wastes energy;
3. The combined control of heating and cooling realizes the rapid response to the absorption or release of heat of the material;
4. The control of material temperature is mainly realized by refrigerant flow control, and the refrigerant proportional control valve adopts the valve body of the electronic expansion valve. Higher temperature control accuracy can be achieved.
The temperature control of the reactor supporting the cooling and heating machine is composed of a refrigeration circulation system, a heating circulation system and an automatic control system. For areas where the equipment has explosion-proof requirements, positive pressure explosion-proof cabinets can be customized to meet explosion-proof requirements.
