GEA Bock Compact Piston Compressors

Southern Sales & Services supply compact piston F Compressors for drive with standard motors via V-belt or direct clutch. Flexible motor arrangement allows for practically all drive-related requirements. Suitable for all current refrigerants, also NH3.

The F model series provides modern open type compressors for separate drive systems (using V belts or direct couplings). Load transfer through a V pair. Virtually all drive capacity requirements can be met.

Very compact compressor design, robust and easy to handle. Oil pump lubrication as standard.

Special features:

  • Compact construction
  • Robust and easy to handle
  • Suitable for V-belt and coupling drive
  • Large number of applications with a wider rpm range
  • Naturally with oil pump lubrication
  • NEW GEA Bock F28
  • GEA Bock F Compressors
  • GEA Bock F NH3 Compressors

The New GEA Bock F28 Compact Piston Compressor

More powerful and more efficient intelligent design never seen before

The largest model from the GEA Bock F28 series offers a displacement of up to 553 m³/h, which means that GEA has closed a performance gap in its product portfolio. In the design of these new 8-cylinder models, GEA combines the expertise from GEA Bock compressors in smaller and medium-sized output ranges with that from large GEA Grasso compressors for industrial refrigeration facilities.

Compared to competitors’ models in this output range, the F28 – thanks to compact dimensions – demonstrates considerably less weight and size, which significantly simplifies installation as well as transport. Despite its great displacement, it is easy to move the F28 through any common ship’s door. This means that no expensive work is necessary on the ships bulkheads, which must be removed for conventional compressor models.

Also with respect to efficiency, the F28 compressor sets new standards for open piston compressors.  As with the previously largest GEA compressors from the F18 series, the GEA Bock mexxFlow valve system is also used in F28 compressors.

This valve system features double lamellar ring design for the valve plate, with optimized flow characteristics, in combination with a cylinder head especially designed for use with this valve plate. By use of this valve system, GEA enhances the efficiency of the compressor by approx. 15 %, compared to the employment of conventional valve-plate engineering. This solution guarantees more cooling duty with less power consumption.

The F28 can basically be operated with all widely used refrigerants. At the fair SMM, the model series presented will provisionally feature only operation with synthetic refrigerants, which will be available in 2015.

GEA F Compressors

The F model series offers modern open compressors for external drive (via V-belt or clutch). Force transmission is by a form-fitting shaft connection. Nearly all drive-related requirements are possible. The compressor design is very compact, robust and easy to handle, naturally with oil pump lubrication.

Special features:

  • Driven via V-belt or direct clutch
  • Suitable for conventional or chlorine-free HFC refrigerants

GEA mexxFlow® valve plate system

More refrigerating capacity and lower power consumption – this is the motto of the mexxFlow® valve plate system, which will form the heart of several new GEA compressor generations in future. Concerning the increase in energy efficiency of semi-hermetic compressors, one focus of compressor manufacturers has always been on the valve plate system. It is necessary to release the energy, which is applied by an electric motor, efficiently to the refrigerating circuit while realizing minimal energy losses. GEA has also put its focus of continuous development of reciprocating compressors on the valve plate system – the mexxFlow® system now reflects the result of this development work.

GEA was successful in increasing the efficiency of its compressors by around 15 % thanks to a flow-optimized double ring fin construction of the valve plate in combination with a cylinder head, which is specially adapted to the valve plate. Thus, open type as well as semi-hermetic commercial GEA compressors achieve new records in terms of efficiency.
