RefComp's 5/6 asymmetric rotor profile helps the screw AC compressor achieve smooth compression, with reduced gas pulsation, vibration and operating noise.
Matched bearing assemblies support axial and radial rotor loads. Precision rolling elements and wear-resistant raceways help the semi-hermetic screw compressor reduce friction and mechanical noise.
A built-in 100 μm suction filter removes impurities from incoming refrigerant gas, helping protect the motor and simplify routine inspection.
The screw AC compressor features a 25-bar pressure design and optimized internal gas passages that help reduce flow resistance and discharge pressure loss. Its integrated construction also simplifies system installation.

For screw AC compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The final selection should be verified against the manufacturer's performance data.
Check the suction, discharge and oil-line connections against the system piping drawings. Ensure the pipework is clean, properly supported and compatible with the compressor connections before installation.
The compressor supports four-stage regulation or stepless capacity adjustment from 25% to 100%. Choose the appropriate control method according to the system's load variations and controller compatibility.
Regularly inspect the suction filter, bearing operating conditions and compressor operating status. Follow the manufacturer's maintenance recommendations to identify contamination or abnormal mechanical conditions early.
