With the new Grasso V reciprocating compressor series, GEA is heralding the start of a completely new era for the industrial refrigeration market.

During the development of the GEA Grasso V series, GEA Grasso continually put itself in the position of the end user. Every component was assessed for the most important elements that contribute to a low Total Cost of Ownership like energy, maintenance and reliability with min. downtime. The result is not only the most effcient reciprocating compressor on the market but also a compressor with electronically controlled service intervals (extended as well as flexible) in order to reduce the Total Cost of Ownership without jeopardizing reliability. This new series replace the existing single stage series in a swept volume range from up to mh. Compound (two stage) compressors will become available in 2013. Features of GEA Grasso V series

Reciprocating compressors for CO2 freezing and NH3 heat pump applications.

GEA Grasso 5HP series
CO2 (Freezing)
CO2 (Freezing) The 50 bar GEA Grasso 5HP compressor, developed for use in CO2 cascade freezing systems, is a well accepted and reliable appearance in the industrial refrigeration market. 4 single stage models from 3 up to 6 cylinders cover a wide range capacities. The extremely low volume ow in relation with the cooling capacity makes this series to a big performer.

NH3 (Heat pump applications)
A logic further development of the GEA Grasso 5HP series is the integration in NH3 heat pump systems. The 50 bar design makes it possible to condensate up to 82 C and as a result of that produce high level of water temperatures. Heat pump systems are developing very quick in various segments of industry (Dairy, slaugther-houses etc.) and contribute in reducing waste heat as well as CO 2 emissions.

The single-stage screw packages of the GEA Grasso SP1 series include 22 package sizes with a capacity range of 130 to 5, 700 kW.

GEA Grasso SP1 series
The smaller size models feature a larger integration level of components and thus a smaller amount of connecting elements. The packages in the bigger capacity area are fitted onto a separate base frame, which ensures running with less noise and vibration.

Technical Features:
Stepless capacity control by frequency inverter and capacity slide
Robust base frame for long motor bearing lifetime
Low positioned gravity center for a low vibration level
Oil separator with variable sizes and low oil charge to achieve an oil carry over of less than 5 ppm
Efficient oil cooler with optional waste heat recovery
System control GEA Grasso GSC a reliable operation
GEA Grasso SP1:
Broad performance spectrum, universal application

Designed for high stage, booster or single stage operation

GEA FES GL series
Features:
Multi-stage oil separator design guarantees low oil loss
Partial-flow, full-time oil pump
