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.
More refrigerating capacity and lower power consumption – this is the motto of the mexxFlow® valve plate system, which will form the heart of several new GEA compressor generations in future. Concerning the increase in energy efficiency of semi-hermetic compressors, one focus of compressor manufacturers has always been on the valve plate system. It is necessary to release the energy, which is applied by an electric motor, efficiently to the refrigerating circuit while realizing minimal energy losses. GEA has also put its focus of continuous development of reciprocating compressors on the valve plate system – the mexxFlow® system now reflects the result of this development work.
GEA was successful in increasing the efficiency of its compressors by around 15 % thanks to a flow-optimized double ring fin construction of the valve plate in combination with a cylinder head, which is specially adapted to the valve plate. Thus, open type as well as semi-hermetic commercial GEA compressors achieve new records in terms of efficiency.
