Product features

●Asymmetric screw rotor designed by RefComp, loberatio profile 5/6, excellent lubrication, perfect meshing between teeth, smooth and quiet operation.

●Small size, filter, cut- off valve, and temperature sensors are integrated into the compressor body. Optimized Design , less space required.

●Motor protection module provides reliable protection against motor overheating, phase reversal and phase loss.

●Real- time tracking provides the operation status of the motor 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 or stepless, in line with full or partial load.

●Unique structure and space design, using subcooled refrigerant gas between suction shut- off valve and the inlet side of the screw to effectively cool down the motor.

●Suction/discharge shut- off valves are able to reverse 360° , which is easily installed with flexibility.
