The Refcomp SW3H-16000 is a 170 HP semi-hermetic screw type compressor engineered for cold room refrigeration. It combines an asymmetric screw rotor profile, a high-precision multi-bearing assembly, integrated safety valve protection and a built-in discharge check valve to deliver efficient, stable and long-term reliable operation in demanding refrigeration systems.
Featuring RefComp's asymmetric screw rotor profile and 5/6 rotor configuration, the compressor provides precise meshing, effective lubrication and smooth compression. The optimized rotor geometry helps reduce vibration and gas pulsation, supporting efficient operation of the semi-hermetic screw type compressor.
The multi-bearing configuration helps accommodate axial and radial loads while reducing mechanical wear and operating noise. High-precision bearings, wear-resistant materials and specialized lubrication contribute to stable operation and long-term mechanical reliability.
The integrated safety valve connects the high- and low-pressure sides, helping prevent excessive internal pressure and providing an additional layer of mechanical protection. This design supports reliable operation of the RefComp screw compressor under demanding refrigeration conditions.
The built-in discharge check valve features low flow resistance and helps prevent refrigerant backflow when the compressor stops. This helps protect the refrigeration system during shutdown and supports smoother system operation.

The SW3H-16000 is a 170 HP semi-hermetic screw type compressor. Selection should consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, cooling medium and electrical supply to ensure proper system matching.
R507A is included among the refrigerants listed in the RefComp SW series documentation. An R507A screw compressor configuration can be considered for compatible commercial refrigeration and freezing applications, subject to confirmation of the selected configuration and actual operating conditions.
The supplied specifications identify 400 V/3-phase/50 Hz and 460 V/3-phase/60 Hz motor configurations. Check the site power supply, motor wiring, starting arrangement and electrical protection before commissioning.
Inspect bearing lubrication, refrigerant connections and the discharge check valve regularly. Also monitor operating noise, vibration and system pressure to identify potential mechanical or operational problems early.
