The Refcomp SW3H-5000 is a 50 HP screw compressor engineered for high-temperature refrigeration and HVAC applications. It combines an asymmetric screw rotor profile with a 5/6 rotor configuration to deliver precise meshing, effective lubrication and smooth compression. The optimized rotor geometry reduces vibration, gas pulsation and operating noise, supporting efficient and reliable performance.
Featuring RefComp's asymmetric screw rotor profile and a 5/6 rotor configuration, the compressor provides precise meshing, effective lubrication and smooth compression. The optimized rotor geometry helps reduce vibration, gas pulsation and operating noise, supporting efficient performance of the RefComp screw compressor.
The HVAC screw compressor offers flexible cooling capacity adjustment according to changing system loads. Four-step capacity control at 25%, 50%, 75% and 100%, or optional stepless regulation from 25% to 100%, helps match compressor output with actual cooling demand and avoid unnecessary full-load operation.
The integrated INT69 SNY protection module monitors motor operating conditions and provides protection against overheating, reverse phase and phase loss. Six series-connected PTC thermistors embedded in the motor windings provide temperature monitoring, helping protect the motor against excessive heat.
The built-in discharge check valve features low flow resistance and helps prevent refrigerant backflow when the compressor stops. Suction and discharge shut-off valves can rotate 360°, providing greater flexibility for piping connections and simplifying installation and maintenance of the HVAC screw compressor.

The SW3H-5000 is a 50 HP screw compressor designed for high-temperature refrigeration applications. When selecting an HVAC screw compressor, consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, cooling medium and power supply.
R134a is included among the refrigerants listed in the RefComp SW series documentation. An R134a screw compressor configuration can be considered for compatible HVAC and chiller applications, subject to confirmation of the selected compressor configuration and operating conditions.
The SW3H series is designed for high-temperature refrigeration applications. It can be evaluated as a screw compressor for HVAC chillers, with final selection based on cooling load, operating temperatures and system requirements.
The supplied specifications identify 400V/3-phase/50Hz and 460V/3-phase/60Hz motor configurations. The starting method, electrical protection and site power supply should be checked before commissioning to ensure proper motor integration.
