GEA Bock HG ATEX Compressors

GEA Bock is the first European manufacturer to offer semi-hermetic compressors certified according to ATEX machine category 2 (zone 1+2). In 2014, GEA also included compressors certified according to ATEX machine category 3 (zone 2) in its program. Within the European Union, electrical and mechanical machinery operated in explosive atmospheres must comply with the so-called ATEX (ATmospheres EXplosibles) conditions. All ATEX compressors are also approved for operation with the current hydrocarbons. The models in the HG Series are the basic compressors for ATEX versions.

The models in the HG Series are the basic compressors for ATEX versions.
