The GEA Bock HG (Hermetic Gas-cooled) range of semihermetic compressors offers traditional suction gas-cooled compressor state of the art technology. These compressors of the highest quality standard excel in their running comfort, easy maintenance, efficiency and reliability.
The entire range of gas-cooled commercial GEA compressors, HG22e, HG34e, HG44e, HG66e and HG88e, is now available in the new, optimized design. In addition to their uses in the fields of refrigeration and air-conditioning, the new compressors are ideally suited for refrigeration in supermarkets. They offer improved efficiency over their predecessors, greater displacement stages, a more compact structural design, and a new configuration of connections.
Capacity data for Low GWP refrigerants R513A as well as R450A are available within our selection software VAP.
Standard valve plate construction
GEA compressors, for smaller and medium-sized capacities, are equipped with a standard valve plate design. This worldwide proven valve design is equipped with finger reed valves on suction and discharge side. The fins are made of high-quality, impact-resistant spring steel. The valve in- and outlets are flow-optimized for smaller and medium-sized capacities in order to reach an efficient compression.

mexxFlow valve plate innovation
More refrigerating capacity and lower power consumption – this is the motto of the mexxFlow valve plate, which forms the heart of the new GEA compressor generations for higher capacities. In order to increase the energy efficiency of reciprocating compressors, manufacturers has always been focused on the valve plate system. At higher capacities the standard valve plates reach their limits in terms of efficiency. With the mexxFlow, GEA was successful in increasing the efficiency of its compressors by up to 20 %. This success was achieved through a flow-optimized double ring fin construction of the valve plate in combination with a specially adapted cylinder head.
With the knowledge gained from practical experience over the past decade, we have consistently improved and further developed the mexx Flow plate system. The result: mexxFlow 2.0.
The second generation shows even greater resistance with a consistent high efficiency. This makes it suitable for the even toughest requirements of various applications.

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.
The compressors are distinguished by high reliability, excellent operating performance, wide frequency band for minimum part-load needs and previously unachievable efficiency standards in the market – confirmed officially through ASERCOM.
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.
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.
