The compressors are used in transcritical and subcritical applications for supermarkets, commercial, industrial refrigeration and heat pumps.
The collected outstanding performance data has also been confirmed officially through ASERCOM (Association of European Refrigeration Component Manufacturers). Therefore the compressors contribute to lowest life-cycle costs and comply with long-term legal requirements such as the F-gas regulation in Europe.
3 model sizes with 14 capacity stages from 6.2 to 38.2 m³/h (50 Hz)

Semi-hermetic HA compressors are primarily used for deep-freezing. Suction gas intake is done directly into the compressor. Motor is cooled by an integrated ventilation unit.
Based on GEA compressors of the Pluscom series with their outstanding advantages and features, more powerful models with 2-pole drive motor are available for mobile use.
Based on GEA compressors of the Pluscom series with their outstanding advantages and features, light construction models made completely of aluminium are available for mobile use.
GEA is the first European manufacturer to offer semi-hermetic compressors conforming to ATEX-/ IECEx zone 1 and 2.
This series offers the advantages of a time-tested compressor series that has been optimally adapted to the demands of CO2.
Natural refrigerants are on the advance. For various applications, such as the field of supermarket refrigeration and chiller systems, hydrocarbons have established as another natural alternative.
The HG model series consists of state-of-the-art classical suction gas-cooled compressor technology. Assurance of effective lubrication by an oil pump, application of exchangeable electrical motors, as well as manufacture of very solid and rugged compressors is ensured. For new advancements in efficiency, GEA has now updated its entire HG range of semi-hermetic compressors.
Based on the 6-cylinder compressor HG7, a selection of two-stage variants is available for extended use in intense cooling. The selection of the liquid intercooler unit is available for three different refrigerants: R404A (R507), R410A and R22.
The GEA Ammonia Dryer removes water from the refrigerant cycle and makes the perfect addition to ammonia refrigeration systems along with filters and purgers.
The GEA Omni control panel is customizable for complete system control — an all-inclusive command center that controls the entire refrigeration system from one panel.
GEA is synonymous with innovation, leadership and precision-engineered solutions. GEA Omni Retrofit Panels extend this tradition. Featuring a high-definition, multi-touch screen, GEA Omni delivers the ease of use and technical wow factor that GEA customers have come to expect.
The GEA Purger removes non-condensable gases from your refrigeration system, maximizing system efficiency.
PR-OLEO® premium-quality ammonia refrigeration oils are highly refined 2-stage hydrocracked lubricants formulated specifically for use in ammonia refrigeration systems with either reciprocating or screw compressors.
