product advantages
  • 1 Down-to-earth investment for the future

    What's important is not initial cost but life cycle cost . INVERTER compressrs may look more expensive than fixed speed model, but many customers choose them because they know importance of life cycle cost & return on investment when it comes to choosing compressors.

    Down-to-earth investment for the future

  • 2 What you pay should be only for what you use

    SCR compressor can adjust compressor's rotating speed depends on the demand of factory load which changes from moment to moment by own developed algorithm. Thus, it can provide exact volume and pressure what customer needs and achieve maximum energy saving.

    Achieve an energy-saving effect under any load operation through wide-range inverter control, wide-range control, and e-STOP function.

    What you pay should be only for what you use

  • 3 Innovative motor oil cooling technology

    Independent closed loop cooling, Special coolant,Independent fan

    Innovative motor oil cooling technology

  • 4 Special morse connection

    Motor rotor is directly mounted on the shaft, No gears or belts, no shaft seal,no coupling, Zero transmission loss, Easy for installation and dismantlement, No need to make adjustment, Better protection for inner parts of PM motor, Reduce maintenance cost.

    Special morse connection

  • 5 Double Frequency conversion system

    Constant pressure output:
    A significant energy-saving effect can be achieved by constant pressure control Pressure fluctuation can be controlled within士0.01MPa.

    Constant temperature output:
    Normally the temperature is set at 81℃,ensure the best lubrication performances while avoid the sudden stop caused by haigh temperature.

    Double Frequency conversion system
