Achieve The Maximum Outcome
at The Lowest Possible Expense


High EER, Low Energy Consumption
The newly symmetrical rotor profile, which has five lobes and six flutes in the male and female rotors respectively, results in a low pressure differential between flutes and provides high volumetric efficiency but low power consumption.

Low Noise Level, Low Vibration
Rotors are precisely processed and dynamically balanced with advanced CRC Rotor Grinding Machines. Supported by high precise bearings, rotors can run smoothly.

Precise Capacity Control System
Four-step or linear capacity control system is available for operations under variable loading conditions with minimum power consumption.

Ease of Maintenance
With semi-hermetic design and limited components used, the detachable motor construction makes compressors easy to maintain.

Wide Application Range
The compressors can be widely used in water and air-cooled air-conditioning systems, thermal storage system, heat pumps or industrial processes if external oil coolers, economizers or liquid refrigerant injection devices is equipped.
