The gas heat exchange system has a pressure resistance of 8bar and a heat exchange cold box with a pressure resistance of 25bar can be customized.
The temperature range is from -40℃~-75℃, which can meet different temperatures;
All use environmentally friendly refrigerants;
Using secondary subcooling technology, cooling is rapid and the extreme temperature is low;
Use well-known brand compressors, mainly self-branded Taikang, Emerson Copeland, and Carlisle;
The evaporator adopts plate heat exchanger, which has small size, long residence time and high efficiency;
Use cold controls (Danfoss pressure controller, balance valve, solenoid valve, filter dryer, Emerson oil separator, etc.);
Using Danfoss expansion valve and Emerson electronic expansion valve, the control accuracy is high;
Adopts Siemens PLC, 7-inch color touch screen display, automatic control operation, and has temperature and pressure curve display, temperature recording USB disk, and fault alarm record;
For complete machine installation, the system has been tested at the factory. The user only needs to install the refrigerant pipeline and cooling water pipeline before operation;

Factory test: Each refrigeration unit is tested under load in the factory for no less than 12 hours;
