Drawing

Low load start-up design: Its start-up load is equivalent to common single-stage compressor, which can avoid great impact on the power grid.

Excellent motor cooling channel: Because of the excellent motor cooling channel design, it can realize the reliable motor cooling under high operation efficiency, so that the compressor can operate in very wide range.

Integrated Design: Medium pressure check valve, stop valve and economizer filter are pre-installed to ensure the reliable protection of the compressor and the simplification of system configuration.

Motor temperature visualization: Optional temperature sensor PT100/PT1000/NTC can be pre-installed in the motor to monitor temperature.
