Refcomp SRC-S-463 screw compressor
,R22 semi-hermetic screw compressor
,HVAC screw compressor with warranty
-
Heavy-Duty Bearing System
The HVAC screw compressor uses matched bearing assemblies to support axial and radial rotor loads. Precision rolling elements and wear-resistant raceways help reduce friction, vibration and operating noise.
-
Flexible Shut-Off Valve Configuration
This air conditioning screw compressor features 360° rotatable suction and discharge shut-off valves for convenient piping installation. An internal discharge check valve prevents refrigerant backflow during shutdown.
-
High-Density Suction Filtration
A built-in 100 μm suction filter removes impurities from incoming refrigerant gas to protect the motor. Its accessible suction-side position simplifies inspection and replacement of the HVAC screw compressor.
-
Flexible Motor Starting and Cooling
The RefComp screw compressor supports partial-winding or star-delta starting configurations to reduce starting current. Suction-gas cooling helps maintain suitable motor operating temperatures.

Q1: What operating information is required to select the SRC-S(W)-463?
To select this HVAC screw compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. Its displacement is 510 m³/h at 50 Hz and 612 m³/h at 60 Hz, but actual cooling capacity must be confirmed using the manufacturer's performance data.
Q2: What should be checked when replacing an existing compressor with the SRC-S(W)-463?
Confirm that the existing refrigeration system accommodates the 105.5 mm suction and 80.0 mm discharge connections. Before installing this semi-hermetic screw compressor, also verify mounting dimensions, electrical compatibility and available service clearance.
Q3: What should I investigate if the SRC-S(W)-463 develops unusual vibration during operation?
Check the mounting bolts, piping supports, suction and discharge pressures, and possible liquid refrigerant return. Persistent abnormal vibration should be investigated promptly to prevent mechanical damage.
Q4: How should refrigerant and lubricant compatibility be verified before servicing?
For this refrigeration screw compressor, the supplied technical data specifies S001 lubricant for R22 and S002 for R407C, R404A and R507. Confirm the existing refrigerant and lubricant specifications before adding or replacing oil.
