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.
