-
Optimized Asymmetric Rotor Design
RefComp's 5/6 asymmetric rotor profile helps the screw type refrigeration compressor maintain smooth compression while reducing gas pulsation, vibration and operating noise.
-
Precision Bearing System
Matched bearing assemblies support axial and radial rotor loads. High-precision bearing components and dedicated lubrication passages help the semi-hermetic screw compressor reduce friction and mechanical 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.
-
Star-Delta Motor Starting
The standard Y/Δ motor configuration supports star-delta starting, helping manage startup current in this low-temperature screw compressor.

Provide the refrigerant, required cooling capacity, evaporating and condensing temperatures, and suction-gas conditions. Confirm the selected model's operating range against the manufacturer's performance data.
Refrigerant compatibility depends on the specific refrigerant, lubricant and operating conditions. Confirm their compatibility before changing refrigerants in a semi-hermetic refrigeration compressor.
Check the system load profile, electrical supply, capacity-control strategy, oil return arrangement and protection interlocks before commissioning an industrial refrigeration screw compressor.
Share the existing model, refrigerant, cooling requirements, operating temperatures, power supply, piping connections and control preferences. This helps confirm whether the screw type refrigeration compressor matches your system requirements.
