Product features

●Asymmetric screw rotor designed by RefComp, loberatio profile 5/6, excellent lubrication, perfect meshingbetween teeth, smooth and quiet operation.
●Small size, filter, cut- off valve, and temperature sensorare integrated into the compressor body. Optimizeddesign , less space required.
●Motor protection module provides reliable protectionagainst motor overheating, phase reversal and phase loss.
●Real- time tracking provides the operation status of themotor and system.
●Multiple duplex bearings are able to avoid rotor axial /radial wear, resulting in high load and low noise.
●Embedded suction filter.
●Solenoid valve conducts capacity control, with step orstepless, in line with full or partial load.
●Unique structure and space design, using subcooledrefrigerant gas between suction shut- off valve and theinlet side of the screw to effectively cool down the motor.
●Suction/discharge shut- off valves are able to reverse360° , which is easily installed with flexibility.
