Centrifugal Chiller

· As it adopts high-efficiency motor direct-driven two-stage impellers with simpler structure for more reliable operation, the size and weight of compressor is only 40% of the conventional compressor with the same cooling capacity.
· It adopts high-efficiency permanent magnet synchronous inverter motor, whose power is over 400kW and rotation speed is over 18,000rpm. Meanwhile, the helical refrigerant ejecting cooling technology is adopted to ensure high-efficiency operation of the motor.
· The design of impeller and diffuser is optimized for achieving high-efficiency operation of compressor in various loads.
· It adopts patented sensor control technology to control the position of motor precisely and improve the reliability.
