The Refcomp SW3H-11500 is a 115 HP R410A air-cooled refrigeration screw compressor engineered for high-temperature applications. It combines integrated mechanical protection, intelligent motor monitoring, and optimized internal flow design to deliver dependable performance in demanding refrigeration and air conditioning systems.
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 screw AC compressor under demanding refrigeration conditions.
Equipped with an INT69 SNY protection module, the compressor monitors motor operating conditions and provides protection against overheating, reverse phase, and phase loss. Six PTC thermistors embedded in the motor windings provide temperature monitoring, helping protect the motor against excessive heat.
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 reduces the risk of contamination-related wear and supports cleaner compressor operation.
The optimized internal gas-passage structure helps reduce flow resistance and exhaust pulsation losses while supporting effective motor cooling. The compact body arrangement contributes to smooth compression operation and efficient system integration.

Q1: How do I select the right SW3H-11500 for my refrigeration or air conditioning system?
The SW3H-11500 is a 115 HP screw compressor designed for high-temperature applications. Selection should consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, cooling medium, and electrical supply to ensure proper system matching.
Q2: Is the SW3H-11500 compatible with R407C refrigerant?
R407C is included among the refrigerants listed in the RefComp SW series documentation. An R407C screw compressor configuration can be considered for compatible air conditioning and chiller applications, subject to confirmation of the selected configuration and actual operating conditions.
Q3: What electrical protection features should be checked before commissioning?
Check the INT69 SNY protection module, PTC thermistor connections, phase sequence, and motor wiring. The electrical protection system should be correctly integrated with the starter to ensure proper motor monitoring and protection.
Q4: What maintenance should be performed on the suction filtration system?
Inspect the suction filter regularly, particularly when contamination is suspected or abnormal operating conditions occur. Cleaning or replacement should follow the manufacturer's maintenance recommendations to help protect the compressor's internal components.
