The main unit is equipped with advance German semi-hermetic screw compressor,
integrating the motor, without worrying about shaft seal leakage.
Multiple refrigerating circuits are provided for the two or more compressors, and when one circuit is
under maintenance, other circuits are able to run normally as a standby.
The two or more compressors are provided with startup-shutdown cycle control program
so as to uniformly load parts and extend their service life.
Unload and step down voltage start is provided for the compressors to prevent the impact on the power grid.
Complete safety protection:
Pressure protection: High and low-pressure protecting devices.
Motor protection: Voltage-loss protection, phase-loss protection, inverse phase protection and
Antifreezing protection: The unit will stop running in case of excessively low chilled water
Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety valve will
be turned on automatically.
Above device protections ensure the safe and reliable running of the unit.
