GEA Grasso X incorporates over 50 years of experience in screw compressors - top efficiency and technology
At the world's leading trade fair Chillventa 2024 in Nuremberg, Germany, GEA presented the semi-hermetic screw compressor CompaX as part of the Grasso X package ideal for seasonal refrigeration applications and flexible capacity requirements.

This Grasso X package consists of three CompaX semi-hermetic compressors. "The compact, safe and reliable design, combined with high efficiency, result in reduced risks and a highly sustainable solution," said Robert Brinckmann, Product Manager Packaged Components at GEA. "We are pleased to bring over 50 years of experience in the development and production of screw compressors to the market with our semi-hermetic series.
Capacity range from 395 to 1,900 kW
Available as a single compressor package and optionally with two, three or four compressors in parallel, it offers a large capacity range from 395 to 1,900 kW (R717 | - 10/+35 °C | 6,000 rpm) as well as flexibility, availability and redundancy. Together with the large variable speed range up to 6,000 rpm, the X-package can be operated in all (partial) load ranges with virtually no loss of efficiency. Based on the semi-hermetic screw compressor models GEA CompaX 350 and 400 without shaft seals, the package is a safe and reliable solution for the use of ammonia, enabling to reach efficiencies to fulfill the Eco Design regulations.
The ultra-compact footprint, another important parameter in the design of the package, facilitates the refurbishment of engine room, for example. A future-proof, efficient and safe solution with minimal space requirements, maintenance effort and overall risks.
Ammonia as a particularly climate-friendly and efficient refrigerant
With an ozone depletion potential (ODP) and global warming potential (GWP) of zero, ammonia is a particularly climate-friendly refrigerant and also a particularly efficient one. It has excellent thermodynamic properties, which are reflected in very high efficiencies and correspondingly low operating costs. Ammonia has always been used in food processing plants, in the beverage and dairy industry as well as in breweries and cold stores - not least due to the very low filling quantities. Last but not least, ammonia is not subject to any restrictions or bans under the EU F-Gas Regulation.
