Heat exchangers of the WEL5 range (photo: WEL5200/M001-D0) are used to cool process/barrier fluids in seal supply circuits. The heat exchangers are made of helical finned tubes. The cooling medium is ambient air. It is important, therefore, for WEL5 heat exchangers to be installed in well ventilated places indoors or, ideally, outdoors. The integrated fan blower ensures the necessary cooling air flow. The WEL5 range is provided as a compact packaged unit completely assembled.

Circulation in accordance with API 682 / ISO 21049: Plan 21, Plan 22, Plan 23, Plan 41


  • Compact Design
  • Can also be used with non-optimal cooling air exchange
  • Helical finned tube with efficient air circulation
  • High resistance to corrosive fluids due to stainless steel components
  • No cooling water supply and heating of cooling water line required in winter

Standards and approvals

  • Calculation based on ASME VIII, Div. 1
