The Refcomp SW3H-24000 is a 240 HP screw refrigeration compressor engineered for parallel HVAC systems and high-temperature refrigeration applications. It combines an efficient suction-gas motor cooling design, an advanced motor protection system, flexible capacity regulation, and integrated suction filtration to deliver stable, reliable performance under demanding operating conditions.
The motor uses incoming suction gas to help dissipate heat from the windings, supporting effective cooling during operation. This design helps maintain stable motor performance and supports reliable operation of the HVAC screw compressor under demanding refrigeration conditions.
The integrated INT69 SNY protection module provides protection against motor overheating, reverse phase and phase loss. Six series-connected PTC thermistors embedded in the motor windings provide temperature monitoring, helping safeguard the motor against excessive heat.
The compressor supports four-step capacity control at 25%, 50%, 75% and 100%, with optional stepless regulation from 25% to 100%. This allows the screw compressor to adjust its output according to changing cooling demand, improving load matching and reducing unnecessary full-load operation.
The built-in 100 μm suction filter captures impurities from refrigerant gas before they enter the compression chamber, helping protect internal components and the motor. This filtration design also simplifies routine inspection and maintenance.

The SW3H-24000 is a 240 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 to ensure proper system matching.
R407C is included among the refrigerants listed in the RefComp SW series documentation. An R407C screw compressor configuration can be considered for compatible HVAC and chiller applications, subject to confirmation of the selected configuration and actual operating conditions.
The four-step or optional stepless capacity regulation allows compressor output to follow changing cooling demand. This provides greater flexibility under partial-load conditions and helps avoid unnecessary full-capacity operation.
Inspect the suction filter regularly, particularly when refrigerant circuit contamination is suspected. Cleaning or replacement should follow the manufacturer's maintenance recommendations to help protect internal compressor components.
