Saying that in industrial as well as maritime applications, system operators often use open-type piston compressors with an external drive when a high degree of reliability, flexibility and operational safety, GEA Refrigeration Technologies has introduced the new GEA Bock compressor models F18 of its GEA Bock F-series. With this, the company reportedly closes the gap between the product lines – GEA Bock and GEA Grasso.

According to GEA, the compressor is available for standard refrigerants with the start of the Chillventa, and a special version for the established refrigerant for industrial systems NH3 (Ammonia) will follow in 2013.

The manufacturer lists the following product features and benefits:

  • The new eight-cylinder compressor model combines the know-how in the small and medium output range with the know-how in the higher output range.
  • For the first time, the GEA Bock mexxFlow valve system is used in this compressor.
  • The mexxFlow system is a flow-optimised double-ring design of the valve plate in combination with a cylinder head especially designed for the valve plate.
  • A plasma-nitrocarburised crankshaft drives the eight pistons of the compressor.
  • Due to the use of the valve system, the company is able to increase the efficiency of the compressor by 15%, compared to the use of standard valve plate technology.
  • It is also significantly smaller than competitors in this capacity range. A fact, that makes the compressor much easier to handle, for instance, for transportation or when taking it into a machine room.
  • The compressor expands the programme of open-type GEA Bock piston compressors upwards with a displacement of up to 280 m³/h.
