Low temperature refrigerant LJ series

Features: The temperature range is from -10 °C to -45 °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 famous brand semi-closed piston compressor, semi-closed piston two-stage compressor and semi-closed screw compressor. The main self-branding is BOCK, Bitzer, Copeland, Hanbell, fusheng; the evaporator uses high-force plate heat exchanger, which is small in size. efficient; 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 unit cooling water circuit uses an intermediate heat exchanger to significantly improve the reliability and safety of the system; The DANFOSS electronic expansion valve has high control precision; Using Siemens PLCS7-200/300 PLC, LNEYA touch screen display, automatic control operation, with temperature curve display, temperature record U disk, fault alarm record; The large-cooling unit adopts a semi-closed screw compressor with an economizer, and is combined with an electronic expansion valve to ensure high efficiency and energy saving;
