-
Optimized Asymmetric Rotor Design
RefComp's 5/6 asymmetric rotor profile helps the semi-hermetic screw compressor achieve smooth compression with reduced gas pulsation, vibration, and operating noise.
-
Integrated Oil Separation System
A built-in multi-stage oil separator with layered oil-mist filtration achieves up to 99.85% separation efficiency, helping maintain reliable lubrication and minimize oil carryover.
-
High-Density Suction Filtration
The semi-hermetic screw compressor features a built-in 100 μm suction filter that captures impurities in incoming refrigerant gas. Its accessible position simplifies inspection and replacement.
-
INT69 SNY Motor Protection
An INT69 SNY protection module works with six PTC thermistors to monitor motor temperature and provide protection against overheating, reverse rotation, and phase loss.

Q1: How do I determine whether the SRC-S(W)-183 meets my refrigeration capacity requirements?
To select this semi-hermetic screw compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The model has a displacement of 205 m³/h at 50 Hz and 246 m³/h at 60 Hz, but actual cooling capacity must be verified against performance data.
Q2: Can the SRC-S(W)-183 adjust its capacity under changing refrigeration loads?
The SRC-S series specifies capacity regulation at 100%, 75%, 50%, and 25%, with stepless control available from 100% to 25%. Confirm the specific capacity control configuration and controller compatibility before ordering.
Q3: What should be considered when installing the SRC-S(W)-183?
The compressor specifies a 67.0 mm (2-5/8") suction connection and a 54.1 mm (2-1/8") discharge connection. Verify piping compatibility, installation clearance, and the standard three-phase power supply of 400 V/50 Hz or 460 V/60 Hz.
Q4: What maintenance checks are important for the SRC-S(W)-183?
Regularly check lubricant condition, operating pressures, motor temperature, and abnormal vibration. For R22 applications, the specified lubricant is S001, with a 7 dm³ oil charge; always confirm refrigerant compatibility and the manufacturer's servicing procedures before maintaining the semi-hermetic screw compressor.
