GEA Introduces Upgraded Semi-Hermetic Compressor Series

GEA Refrigeration Technologies has upgraded its range of semi-hermetic compressors and from 2014 will offer new, efficiency-optimized solutions for applications in refrigeration and climate control. 

The new HG44e (4- cylinder) and HG88e (8-cylinder) models are already available, and two new the HG56e and HG76e will also be on the market this autumn. The HG76e and HG88e compressors are equipped with the newly developed GEA Bock mexxFlow valve-plate technology, which enables greater refrigeration duty while operating with less power consumption. 

GEA Refrigeration Technologies has based these four new semi-hermetic compressor series on the principles of GEA Bock compressors, which include assurance of effective lubrication by an oil pump, application of exchangeable electrical motors, as well as manufacture of very solid and rugged compressors.

The HG44e Series

The new GEA Bock HG44e compressors replace the HG4 series and are characterized by increased efficiency, greater displacement, more compact design, and a new configuration of connections. These connections match gas fittings currently provided, which enables replacement investment without adaptation. The series offers four instead of three model sizes, compared with the previous models.

The HG88e Series

GEA Bock HG88e compressors have already been on the market for several months. The largest GEA Bock 8-cylinder for commercial refrigeration presently on the market is available in two model sizes: from 237.9 to 281.3 m³/h.

The HG56e Series

Beginning in autumn of this year, a total of three 6-cylinder models in the HG56e series will replace the previous GEA Bock HG5 series. These new compressors will be available with displacements of 73.8 to 100.4 m³/h. Throughout the portfolio, 6-cylinder compressors will then be offered instead of the previous HG5 4-cylinder models. Compared to the 4-cylinder compressor models typically available on the market, the increase in number of cylinders leads to enhanced efficiency and to optimized noise-emission levels

The HG76e Series

Also from autumn of 2014, the new GEA Bock HG76e series of models will arrive on the market to upgrade their predecessor models from the HG7 series. The new 6-cylinder compressors are characterized by more efficient design of the gas ducts as well as optimized electric motors from the latest generation. In combination with mexxFlow valve-plate technology, total efficiency enhancement of up to 15 percent is possible.
