GEA Grasso SH The GEA Grasso SH series comes in four sizes and covers swept volumes ranging from 231 to 372 m3 /h. The simple design results from integration of the entire oil management system with only one oil connection. Connections are also possible for pressure and temperature sensors as well as slide position indicators and solenoid valve blocks for Vi (internal volume ratio) and for capacity adjustment. Direct assignment of the solenoid valves and various connection options allow easy assembly and service work on the package. The parallel slide system enables infinitely variable...

GEA Grasso M GEA Grasso M compressors are the first screw compressors with an integrated pressure-activated check valve ensuring low pressure drop. The integration of the suction filter and coupling housing ease assembly of the package. The outstanding energy-efficiency of these compressors is based on the infinitely adjustable capacity combined with the extended variable Vi-range. The variable speed from 1,000 to 4,500 rpm via frequency inverter especially ensures maximum efficiency in full and part load. GEA Grasso M comes in four model sizes and covers a swept volume range from 471 to...
