The Refcomp SW3L-13000 is a 130HP (98 kW) refrigeration screw compressor engineered for freezing cold room applications. Built around an optimized asymmetric rotor profile and supported by integrated pressure, filtration and motor-protection systems, it delivers stable, efficient compression in low-temperature refrigeration environments.
The SW3L-13000 refrigeration screw compressor features RefComp's asymmetric 5/6-tooth rotor profile, promoting smooth rotor engagement and reduced vibration. Its optimized geometry supports efficient compression and stable mechanical operation in low-temperature refrigeration systems.
This RefComp screw compressor features an internal safety valve connecting the high- and low-pressure sides. Its precise opening and reliable reset help prevent excessive pressure differences, providing additional protection against abnormal operating conditions.
The integrated 100 μm suction filter captures impurities from incoming refrigerant gas before they reach the motor. This helps protect internal components from contamination, reducing the risk of damage caused by foreign particles.
The INT69 SNY protection module works with six PTC temperature sensors to protect against motor overheating, reverse phase sequence and phase loss. Operating-status feedback helps technicians identify abnormal conditions and troubleshoot electrical faults more efficiently.

When selecting a refrigeration screw compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply and expected load conditions. Compare these requirements with the compressor's approved operating range before ordering.
A screw compressor for refrigeration systems requires a properly matched oil separation and return arrangement. Since the SW3 series has no integrated oil separator, verify the external oil circuit, filtration and flow-protection devices against the manufacturer's requirements.
Before starting this screw refrigeration compressor, verify the motor power supply, star-delta starter connections, phase sequence and INT69 SNY protection wiring. Ensure the lubrication circuit and protective controls are functioning correctly before initial operation.
When replacing an existing refrigeration screw compressor, compare the mounting dimensions, suction and discharge connections, capacity-control configuration and electrical interfaces. These checks help identify potential installation and control compatibility issues before replacement.
