For drive with standard motors via V-belt or direct clutch. Flexible motor arrangement allows for practically all drive-related requirements. Suitable for all current refrigerants, also NH3.

The GEA Grasso SH series comes in four sizes can cover swept volumes ranging from 231 to 372 m3h. 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.

The GEA Grasso MC series comes in four sizes with a swept volume ranging from 471 to 860 m3h. They have a simple and compact design between the compressor and package, where some unit components may come already integrated such as a suction side non-return valve, suction filter, an oil pump along with an oil and hydraulic system with the appropriate solenoid valve assemblies for Vi and part load adjustment. The control lines for the solenoid valve for Vi part load controls are connected directly to the compressor.
