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.
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.
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.
