The Refcomp SW3H-10500 is a 105 HP (78 kW) twin-screw compressor engineered for rooftop air conditioning and refrigeration applications. Built around RefComp's asymmetric screw rotor profile, it delivers precise meshing, effective lubrication and smooth compression for reliable, efficient operation.
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 and gas pulsation, supporting efficient operation of the AC screw compressor.
The motor uses incoming suction gas to help dissipate heat from the windings, supporting effective cooling during operation. Partial-winding or star-delta starting helps reduce starting current, while the motor configuration accommodates different electrical supply requirements.
The compressor supports four-step capacity control at 25%, 50%, 75% and 100%, with optional stepless regulation from 25% to 100%. This allows the AC screw compressor to adjust its output according to changing cooling loads, improving load matching and reducing unnecessary full-load operation.
The built-in discharge check valve features low flow resistance and helps prevent refrigerant backflow when the compressor stops. Combined with flexible shut-off valve positioning, this design simplifies system integration and provides greater convenience during installation and maintenance.

The SW3H-10500 is a 105 HP screw compressor designed for high-temperature refrigeration applications. Selection should consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, cooling medium and electrical supply. These factors help determine whether the AC screw compressor matches your project requirements.
R134a is included among the refrigerants listed in the RefComp SW series documentation. An R134a screw compressor configuration can be considered for compatible air conditioning and chiller applications, subject to confirmation of the selected configuration and actual operating conditions.
Yes. The four-step and optional stepless capacity regulation systems allow compressor output to respond to changing cooling demand. This makes the compressor suitable for air conditioning systems with varying load requirements.
Check the motor wiring, phase sequence, starting arrangement, refrigerant piping and shut-off valve connections. The electrical supply and protection settings should match the selected motor configuration before the compressor is put into operation.
