BOCK F compressors

Open compressors

BOCK F-Series for marine and stationary refrigeration

Compressors of the Bock F-series are ideally suited for the high demands of shipping: for air-conditioning cabins and cooling supplies on passenger ships, containers, or fishing boats. In the stationary refrigeration sector, the reciprocating compressors offer extremely easy handling. And this even under challenging conditions such as unreliable or varying voltage supply.

More Producthighlights

Bock F-compressors are a high-quality alternative for industrial refrigeration applications with consistently high efficiency. Especially our F76 and F88 series:

  • More compact, more cost-effective with higher efficiency
    compared to industrial compressors in this performance range
  • Reduced maintenance intervals for industrial refrigeration processes
  • Highly efficient valve plate system mexxFlow 2.0 proven with semi-hermetic large Bock seals, now integrated in the F76 and F88 compressor series and even more resistant than the previous version

  • Oil supply for reliability and durability
  • Oil pump lubrication system independent of direction of rotation
  • Minimised oil throw
  • Service-friendly oil strainer
  • Large-volume oil sump with connection options for oil pressure monitoring and
  • Oil level regulator (standard)

For rough ship conditions and confined spaces

Highlights in Set and Series

Raised base plate
  • For use of additional  oil volume in the compressor in rough conditions such as severe fluctuations on a ship (F76: 2.7 l; F88: 4.6 l)
  • Raised base plate - low base plate: decide according to your requirements!


Footstep protection

Confined spaces require robust, hard-wearing components. Bock protects sensitive compressor elements with a kick plate (accessory) in challenging conditions and tight machine rooms.
