Refcomp SW3L-16000 170HP R22 Semi-Hermetic Screw Compressor

Rotors: Engineered for demanding industrial cooling, this semi hermetic screw compressor features an asymmetric rotor profile with a 5/6 lobe combination, delivering high structural strength and low-noise operation. Its optimized length-to-diameter ratio enhances high-pressure efficiency, making it exceptionally reliable for low-temperature application cycles.

Body: The robust casing structure of this semi hermetic screw compressor is rated for maximum working pressures up to 25 bar, featuring optimized internal gas channels that reduce inlet resistance. The compact housing seamlessly combines the suction filter, stop valves, oil separator, and temperature sensor interface.

Motor Protection: Equipped with an INT69 SNY protection module and six series-linked PTC thermistors embedded directly within the windings, this semi hermetic screw compressor guards against thermal overload, phase loss, and phase reversal. Real-time diagnostic signal outputs ensure continuous monitoring and system security.

Stop Valves: Featuring 360° rotatable suction and discharge stop valves, this unit allows for flexible, space-saving pipeline integration. An integrated discharge check valve reliably prevents high-pressure refrigerant backflow into the suction side during system shutdown.
