the gas heat exchange system has a pressure resistance of 25 bar;
the temperature range is from -40 C to -75 C, which can meet different temperatures;
All use environmentally friendly refrigerants;
Using secondary subcooling technology, the refrigeration is rapid and the limit temperature is low;
It adopts imported brand semi-closed piston compressor, scroll flexible compressor and fully enclosed piston compressor. the main brands are Duling, Taikang and Emerson;
the evaporator adopts a casing type heat exchanger, which has small volume, long residence time and high efficiency;
Use a full set of imported cold controls (DANFOSS pressure controller, balance valve, expansion valve, solenoid valve, dry filter, Emerson oil separator, ALCO sight glass, check valve, etc.);
the use of Danfoss expansion valve, Emerson electronic expansion valve, high temperature control accuracy;
It adopts Siemens PLCS7-200/300PLC and LNEYA touch screen display to carry out automatic control operation, and has temperature curve display, temperature record U disk, fault alarm record;
the whole machine is installed, the system has been tested in the factory, and the user only needs to install the refrigerant pipeline and the cooling water pipeline to complete the operation;
Factory test: Each refrigeration unit is tested at the factory with a load of not less than 12 hours;
