Product Description

Heat exchangers of the HED range are used to cool process/barrier fluids in seal supply circuits. Designed as a tubular heat exchanger with integrated guide plates, the process/barrier medium is directed through the shell of the HED and the cooling medium through the tubes.

Circulation in accordance with API 682 / ISO 21 049: Plan 21, Plan 22, Plan 23, Plan 41

Technical Features

  • It can be installed either in vertical or
    horizontal position
  • The heat exchanger can be dismantled: easy
    to clean
  • Tubular heat exchanger design with
    integrated guide plates, extremely efficient
    cooling capacity yet very compact dimensions
  • Universal usage: parts in contact with the
    medium are made of stainless steel

Typical Industrial Applications

  • Chemical industry
  • Oil and gas industry
  • Petrochemical industry
  • Power plant technology
  • Refining technology


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