WDK5120 heat exchangers are used to cool process/barrier fluids in seal supply circuits. The heat exchanger has a wound double helix around the guide tube. Process/barrier medium in the tubes, cooling medium around the tubes.

Circulation based on API 682 / ISO 21049: Plan 21, Plan 22, Plan 23, Plan 41


  • Effective cooling: with wound double helix around a guide tube
  • Cooling capacity up to 10.5 kW
  • Excellent value for money
  • Vessel can be dismantled: for optimum cleaning of the cooling water side
  • Universal usage: parts in contact with the buffer medium are made of 1.4571

Standards and approvals

  • PED 2014/68/EU, Art. 4, Paragraph 3 (Design and production in accordance with EU Pressure Equipment Directive, without CE-Sign)


Mount vertically with connections pointing up. Provide for external venting on the process/barrier medium side (the user has to install a vent at the highest point of the pipe work).

Cooling water side: the area around the tubes can be cleaned mechanically after the housing is removed.
Buffer medium side: flush with a suitable solvent.
