Bock HG Compressor Range

The Bock HG (Hermetic Gas-cooled) range of semi hermetic compressors offers traditional suction gas-cooled compressor state of the art technology. These compressors of the highest quality standard excel in their running comfort, easy maintenance, efficiency and reliability.

The entire range of gas-cooled commercial compressors, HG22e, HG34e, HG44e, HG66e and HG88e, is now available in the new, optimized design. In addition to their uses in the fields of refrigeration and air-conditioning, the new compressors are ideally suited for refrigeration in supermarkets. They offer improved efficiency over their predecessors, greater displacement stages, a more compact structural design, and a new configuration of connections.

Special features:

  • New design housing for maximum gas flow
  • Optimized valve plate system
  • High efficiency motors of newest generation
  • Exchangeable motor
  • Proven and reliable oil pump lubrication
  • Standard footprints
  • Standard connections

Capacity data for Low GWP refrigerants R513A as well as R450A are available within our selection software VAP.

GEA Valve plate systems

Standard valve plate construction
Compressors, for smaller and medium-sized capacities, are equipped with a standard valve plate design. This worldwide proven valve design is equipped with finger reed valves on suction and discharge side. The fins are made of high-quality, impact-resistant spring steel. The valve in- and outlets are flow-optimized for smaller and medium-sized capacities in order to reach an efficient compression.

mexxFlow valve plate innovation
More refrigerating capacity and lower power consumption – this is the motto of the mexxFlow valve plate, which forms the heart of the new compressor generations for higher capacities.  In order to increase the energy efficiency of reciprocating compressors, manufacturers has always been focused on the valve plate system. At higher capacities the standard valve plates reach their limits in terms of efficiency. With the mexxFlow, Bock was successful in increasing the efficiency of its compressors by up to 20 %. This success was achieved through a flow-optimized double ring fin construction of the valve plate in combination with a specially adapted cylinder head.

With the knowledge gained from practical experience over the past decade, we have consistently improved and further developed the mexx Flow plate system. The result: mexxFlow 2.0.

The second generation shows even greater resistance with a consistent high efficiency. This makes it suitable for the even toughest requirements of various applications. HG66e + HG88e

The HA (Hermetic Air-cooled) range, specially engineered by Bock, is available for deep-freezing applications, in particular for use with the refrigerants R22 and R404A.
