-
Optimized Asymmetric Rotor Design
RefComp's 5/6 asymmetric rotor profile helps the semi-hermetic screw compressor achieve smooth compression while reducing gas pulsation, vibration and operating noise.
-
Precision Bearing System
The multi-bearing arrangement supports axial and radial rotor loads. High-precision bearing components and dedicated lubrication passages help reduce friction, mechanical wear and operating noise.
-
INT69 SNY Motor Protection
The INT69 SNY protection module works with six series-connected PTC thermistors to monitor motor temperature and provide protection against overheating, reverse rotation and phase loss.
-
Integrated Pressure Safety Valve
An internal safety valve connects the high- and low-pressure sides, helping prevent excessive pressure differentials within the compressor housing and supporting safe operation.

Q1: How can I confirm whether this compressor is suitable for a cold storage project?
Provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. These details help verify whether the cold storage screw compressor matches your actual low-temperature operating requirements.
-
Q2: What should I check if the compressor develops abnormal vibration or noise?
For a semi-hermetic screw compressor, inspect bearing lubrication, mounting conditions, piping stress and operating parameters. Sudden changes in vibration or noise should be investigated before continued operation.
-
Q3: What should be confirmed before changing the refrigerant or lubricant?
Before modifying a refrigeration screw unit, confirm refrigerant compatibility, lubricant specifications and operating limits with the manufacturer. An unverified refrigerant or oil change may affect compressor reliability.
-
Q4: What information should I prepare when requesting technical support?
For a semi-hermetic refrigeration compressor, provide operating pressure and temperature records, refrigerant details, running conditions and any protection alarms. This helps technical personnel distinguish compressor-related problems from system-side issues.
