Compact High-Pressure Housing
The AC screw compressor features a 25-bar housing with optimized internal gas passages to reduce flow resistance. Its compact structure integrates the suction filter, shut-off valve and temperature sensor.
-
Precision Bearing Assembly
Combined bearing assemblies support axial and radial rotor loads, while precision rolling elements and wear-resistant raceways help reduce friction, vibration and operating noise.
-
Integrated Pressure Safety Valve
An internal safety valve connects the high- and low-pressure sides, helping protect the compressor against excessive internal pressure and supporting safe operation.
-
Flexible Shut-Off Valve Design
The AC screw compressor incorporates a discharge check valve to prevent refrigerant backflow during shutdown. Its 360° rotatable suction and discharge shut-off valves simplify piping installation and servicing.

Q1: How do I select the SRC-S(W)-213 for an air conditioning system?
Selecting this AC screw compressor requires the cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. Its displacement is 237 m³/h at 50 Hz and 284 m³/h at 60 Hz, while actual cooling capacity must be verified against performance data.
-
Q2: How does the SRC-S(W)-213 handle changing cooling loads?
The SRC-S series specifies capacity regulation at 100%, 75%, 50% and 25%, with stepless regulation from 100% to 25%. Confirm the installed capacity control configuration and controller compatibility before commissioning.
-
Q3: What electrical and installation requirements should be checked?
The standard motor supply is 400V/3/50Hz or 460V/3/60Hz. Verify the motor starting configuration, electrical protection, piping connections and installation clearance before connecting the compressor.
-
Q4: What lubrication precautions are necessary for the SRC-S(W)-213?
For R22 applications, the specified lubricant is S001, with an oil charge of 7 dm³. Check oil condition and level regularly, and confirm lubricant compatibility before servicing or changing the refrigerant.
