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

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 supply oil automatically at low temperature.
