Zephyr PM compressors

The PM-series Zephyr compressor technology allows for the precise adjustment of the required amount of compressed air. In combination with high-efficiency permanent magnet synchronous motors, PM-series compressors achieve a constant efficiency of up to 97% over the entire control range. The energy savings are up to 40% compared to standard screw compressors.

Advantages of Zephyr PM compressors:

  • High-efficiency, maintenance-free synchronous permanent magnet motors that do not have any bearings
  • Direct drive – the motor is mounted directly on the shaft of the spiral
  • Unlimited number of starts/stops
  • Shutdown instead of running idle to save energy; the compressor does not have an unloaded state
  • High-efficiency frequency converters with the latest Vector control technology
  • Smooth, soft start; the starting current is always lower than during full load
  • Dimensioned for continuous 24/7 operation
  • Stable constant pressure
  • The automatic coolant temperature control prevents the accumulation of water condensate
  • Coolers enlarged by 30%
  • Latest generation of microprocessor control with remote access capability
