WEF6
Water cooler

Features

Heat exchangers of the WEF6 range are used to cool process/barrier fluids in seal supply circuits. WEF6 heat exchangers are fully compliant with API 682 4th edition regulations. The process/barrier medium is directed through the tube, and the cooling medium is directed through the shell.
Venting and draining of the process/barrier medium side as well as the cooling water side is ensured. In addition, the heat exchangers can also be combined with a temperature instrument in the supply line to the mechanical seal (optional in accordance with API 682 4th edition).

Advantages

  • Operating limits up to 65 bar / 260 °C
    (943 PSI / 500 °F) (tube side):
    suitable for a wide range of operations
  • Cooling water and process side can be completely vented and drained
  • Seamless pipes on process side
  • Special design without welding inside the cooler
  • Higher cooling water velocity due to innovative cooler design
  • Stainless steel 316/316L: high resistance to corrosive media

Standards and approvals

  • PED 2014/68/EU (Design and production in accordance with EU Pressure Equipment Directive)
  • ASME VIII, Div. 1 possible (see notes)
  • API 682 4th edition

Notes

Design and production in accordance with EU Pressure Equipment Directive PED 2014/68/EU.
Design, calculation and production acc. to ASME VIII, Div. 1
(cooler not subject to ASME stamp requirements, piping <6")


Cleaning:
Process/barrier medium side and cooling water side: flush with a suitable solvent.
