The Refcomp SW3L-9500 is a 95HP (71kW) screw refrigeration compressor engineered for air conditioning and industrial refrigeration systems. It combines flexible capacity control, precision multi-bearing rotor support, intelligent motor protection and integrated pressure safety protection to deliver stable, efficient and reliable compression performance.
The SW3L-9500 uses a slide-valve system with stepped capacity control or an optional stepless configuration. As a variable capacity screw compressor, it helps match output to changing cooling loads and reduces unnecessary full-capacity operation.
The multi-bearing arrangement supports both axial and radial rotor loads, helping maintain stable alignment during compression. Precision fitting and effective lubrication reduce mechanical friction and noise, supporting smoother operation and limiting component wear.
The INT69 SNY protection module works with six PTC temperature sensors to help protect against motor overheating, reverse phase sequence and phase loss. Operating-status feedback makes abnormal conditions easier to identify, supporting timely troubleshooting and reducing the risk of motor damage.
The internal safety valve connects the high- and low-pressure sides to help prevent excessive pressure differences. Its controlled opening and reliable reseating provide additional protection during abnormal operating conditions, helping reduce the risk of pressure-related damage.

For an industrial refrigeration screw compressor installation, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply and expected load conditions. The screw refrigeration compressor should be checked against its approved operating range before selection.
Yes. The SW3 series does not include an integrated oil separator, so a properly matched external oil separation and return arrangement is required. Check oil filtration, flow protection and piping connections against the manufacturer's installation requirements.
The SW3L-9500 uses star-delta motor starting. Before starting this 95 HP screw compressor, verify the supply voltage, starter wiring, phase sequence and motor protection connections against the manufacturer's electrical diagram.
When replacing an existing screw refrigeration compressor, compare the required operating range, mounting dimensions, suction and discharge connections, oil-line fittings and capacity-control interface. These checks help identify potential mechanical and electrical compatibility issues before installation.
