GEA Grasso screw compressor SH series

The GEA Grasso SH series comes in four sizes can cover swept volumes ranging from 231 to 372 m3/h.

The simple design is owed by the integration of the complete oil management system with only one oil connection and important package elements in the compressor. The screw compressors come equipped with connections for monitoring pressure and temperature, for position displays on the control screen, and for controlling the integrated solenoid valve assembly for combined Vi part load adjustment.

The direct assignment of the solenoid valves to Vi and part load regulation and the connection of pressure and temperature sensors on the compressor ease assembly and service work on the package. The parallel slide system allows for Vi optimization and part load adaptation to take place simultaneously and independently of one another. It means that even in part load operations a low-loss work process is possible for the screw compressor.

Technical features:

  • Integration of package components
  • Integration of oil management system
  • Compact design
  • Suitable for all standard DIN-flange motors
  • Rotors fully bedded on roller bearings
  • Capacity and Vi control by parallel slide system
