Bock FK Compressors – In Touch with Eberspächer Sütrak
Bock vehicle compressors in the FK series are the result of decades of experience in mobile refrigeration. Particularly when it comes to bus air-conditioning, they are the standard of all renowned manufacturers namely Eberspacher Sutrak.
The unsurpassed light, compact, robust design and wide rpm range are only some of the outstanding features of this unique product range of 2-, 4- and 6-cylinder compressors.
One special innovation constitutes the so-called K version with a unique valve plate system for the toughest demands in mobile air-conditioning.
More information about the FK compressors for bus and rail air conditioning (e.g. technical/performance data, drawings, spare part lists, operating limits) can be found in the compressor selection tool VAP via the following link: VAP compressor selection FK compressors
Bock HG Compressors – In Touch with Eberspächer Sütrak
Based on Bock compressors of the Pluscom series with their outstanding advantages and features, light construction models made completely of aluminium are available for mobile use.
Especially for use in air conditioning systems in electrically-operated buses and rail air conditioning systems, Bock also offers a special lightweight aluminium version of the semi-hermetic HG compressor for mobile applications.
These compressors weigh approx. 40% less than comparable standard compressors and are available with 7 displacement levels.
More information about the HG Alu compressors (e.g. technical/performance data, drawings, spare part lists, operating limits) can be found in the compressor selection tool VAP via the following link: VAP compressor selection HG Alu compressors
Based on Bock compressors of the Pluscom series with their outstanding advantages and features, more powerful models with 2-pole drive motor are available for mobile use.
