Operation Panel

7-inch color touch screen controller, temperature curve record, data export to excel format.

Safety protection

Self-diagnosis function; freezer overload protection; high pressure switch, overload relay, thermal protection device,

liquid low level protection, high temperature protection and temperature fault protection.

Closed circulation system

The whole system is full closed circulation, there is no oil mist at high temperature and no water vapor at low temperature,

pressure do not rise up when system is running. The system will supplement oil automatically at low temperature.
