-
Heavy-Duty Bearing System
Precision bearing assemblies support axial and radial rotor loads, while wear-resistant rolling elements and specially designed raceways help reduce friction, vibration and operating noise.
-
Integrated Pressure Safety Valve
The refrigeration screw compressor features an internal safety valve connecting the high- and low-pressure sides, helping prevent excessive pressure within the compressor housing.
-
Flexible Suction and Discharge Valves
A built-in discharge check valve prevents refrigerant backflow during shutdown, while 360° rotatable suction and discharge shut-off valves simplify piping installation and servicing.
-
Efficient Motor Design
Partial-winding or star-delta starting configurations help reduce startup current. The motor also uses suction-gas cooling to maintain suitable operating temperatures.

Selecting this refrigeration screw compressor requires the cooling capacity, refrigerant, evaporating and condensing temperatures, and power supply specifications. The manufacturer's performance data should be checked to confirm suitability for the intended operating conditions.
The compressor series specifies capacity regulation at 100%, 75%, 50% and 25%, with stepless control from 100% to 25%. Confirm the control configuration and system requirements before commissioning.
Verify the suction and discharge piping connections, mounting arrangement, electrical supply and available service space. The refrigeration screw compressor also requires proper refrigerant piping preparation, leak testing and evacuation before startup.
Regularly monitor oil condition, operating pressures, motor temperature and abnormal vibration. For R22 applications, the specified lubricant is S001; confirm refrigerant and oil compatibility before servicing the refrigeration screw compressor.
