Security Protection

With self-diagnosis function; refrigerator overload protection; high pressure switch, overload relay, thermal protection device, high temperature protection, sensor fault protection and other security functions

closed circulation system

The whole system is a fully closed system, there will be no oil mist at high temperature, and the water in the air will not be absorbed at low temperature. The system will not increase the pressure due to high temperature during operation, and the heat conduction medium will be automatically supplemented at low temperature.
