Universal Hydraulik CKM/FS Heat Exchanger SeriesBased on the existing oil/water heat exchangers of the CKM series, Universal Hydraulik developed the new oil/water safety heat exchanger CKM/FS which, by means of a double tube, prevents the danger of mixing the cooling and the to be cooled medium. The space between the two tubes is filled with a sealing liquid, which enables optimum heat transfer.

A pre-charged diaphragm accumulator compensates the thermal change in volume of the sealing liquid and keeps the sealing liquid pressure almost constant. Any leaks in the bank of tubes are indicated at once by the pressure switches. These two characteristics, the pre-charging of the system in connection with the min. and max. pressure monitoring guarantee an independent operating pressure for the cooling of as well as the to be cooled medium.

Product Features:

  • Version with/for double pipes
  • Protection against overpressure as well as corrosion effects
  • Expansion tank with pressure control for acceptance of changes in sealing liquid volume
  • Removable sealing cover for cleaning internal water pipes


  • Sea water version
