Security 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 closed circulation system. At low temperature system did not absorb water vapor
& also at high temperature did not produce the oil mist. Also at high temperature pressure will not go
up during the system is operating & at low temperature the system will supplement oil.
