Refcomp SW3H-6000 R410a High-Temperature HVAC Screw Compressor for Refrigeration
Refcomp SW3H-6000 screw compressor
,R410a HVAC screw compressor
,high-temperature refrigeration screw compressor
The SW3H-6000 HVAC screw compressor supports four capacity stages at 25%, 50%, 75% and 100%, or stepless regulation from 25% to 100%, allowing compressor output to adapt to changing cooling loads.
An internal safety valve connects the high- and low-pressure sides to help prevent excessive pressure differentials. Its responsive opening mechanism provides additional protection for this HVAC screw compressor.
The semi-hermetic screw compressor uses an INT69 SNY protection module with six series-connected PTC thermistors to monitor motor temperature and protect against overheating, reverse rotation and phase loss.
A built-in 100 μm suction filter captures impurities from incoming refrigerant gas, helping protect the motor. Its suction-side position provides convenient access for inspection and replacement in this air conditioning screw compressor.

Q1: What information is needed to select the correct compressor for an HVAC system?
When selecting an HVAC screw compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The SW3H-6000 has a displacement of 175 m³/h at 50Hz and 210 m³/h at 60Hz, but actual cooling capacity must be verified against manufacturer performance data.
Q2: What electrical preparations are required before commissioning?
The RefComp screw compressor uses a standard star-delta motor starting arrangement with 400V/3/50Hz or 460V/3/60Hz power supplies. Verify the starter wiring, contactor sequence, electrical protection settings and available power supply before the initial startup.
Q3: What should be considered when replacing an existing compressor?
Compare the existing piping connections, mounting dimensions, electrical requirements and installation clearance with the replacement unit. The SW3H-6000 specifies a 54mm suction connection, a 42mm discharge connection and a weight of 265kg, which should be considered during installation planning.
Q4: What should I check if the compressor runs but provides insufficient cooling?
Check the actual evaporating and condensing conditions, refrigerant supply and capacity control position. Compare the measured operating conditions with the original selection data to determine whether the problem originates from the compressor settings or the refrigeration system.
