GEA GRASSO SP2

GEA Grasso SP2 is a unique solution specifically suited for low evaporation temperatures and high temperature lifts and high differential pressures. Each two-stage screw compressor package of this series includes two separate drivelines in serial arrangement: a low-pressure plus high-pressure compression stage that ensure a most efficient and flexible operation.

A GEA Grasso SP2 package is the efficient and flexible solution for high differential pressure operation. At the same time, the package – based on a common base frame, oil circuit and common control – is easier to install, operate and maintain, and it requires less space than two separate single-stage packages. Thanks to GEA’s state-of-the-art engineering even less than common compound solutions.

The unique design featuring two separate drivelines also offers significant redundancy and flexibility advantages over compound solutions. Individual speed regulation of the two drivelines ensures maximum efficiency also in varying operating conditions and load requirements. Additional flexibility and availability are provided by the possibility to switch off the low-pressure compression stage, for example when servicing the booster compressor or in case low-temperature refrigeration is temporarily not required but only A/C cooling which can supplied by the high-pressure compression stage.

The series includes 18 models (booster screw compressors, each available with several different high-pressure compressor combinations) covering a wide range of 118 to 2,100 kW refrigeration capacity (R717 | -40/+35°C | 3,600 rpm).
