Optimized Asymmetric Rotor Design
RefComp's 5/6 asymmetric rotor profile optimizes compression efficiency and reduces gas pulsation. Precision rotor geometry helps the screw air conditioning compressor operate smoothly with lower vibration and noise.
-
Integrated Oil Separation System
A built-in multi-stage oil separator with layered oil-mist filtration achieves a stated separation efficiency of 99.85%. The internal oil reservoir supports continuous lubrication while reducing oil carryover into the refrigeration system.
-
Internal Pressure Safety Valve
A built-in safety valve connects the high- and low-pressure sides to help prevent excessive internal pressure. Its responsive opening mechanism provides additional protection for the screw air conditioning compressor.
-
INT69 SNY Motor Protection
The INT69 SNY protection module uses six series-connected PTC thermistors to monitor motor temperature, providing protection against overheating, reverse rotation and phase loss.

Q1: How do I select the SRC-S(W)-305 for my air conditioning system?
Selecting this screw air conditioning compressor requires the cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. Its displacement is 341 m³/h at 50 Hz and 409 m³/h at 60 Hz, while actual cooling capacity must be confirmed using the manufacturer's performance data.
Q2: How does the SRC-S(W)-305 respond to varying cooling loads?
The SRC-S series supports capacity regulation at 100%, 75%, 50% and 25%, with stepless adjustment from 100% to 25%. Confirm the required control configuration and compatibility with the system controller before commissioning.
Q3: What installation requirements should be checked for the SRC-S(W)-305?
The compressor specifies an 80.0 mm (3-1/8") suction connection and a 54.1 mm (2-1/8") discharge connection. Verify piping compatibility, motor starting arrangements and the standard 400V/3/50Hz or 460V/3/60Hz power supply before installation.
Q4: What lubricant and maintenance precautions apply to the SRC-S(W)-305?
For R22 applications, the specified lubricant is S001, with an oil charge of 10 dm³. Regularly monitor oil condition, operating pressures and motor temperature, and verify lubricant compatibility before servicing.
