Features

Heat exchangers of the WEL6000A4 range (shown here: WEL6002A4) are used to cool process/barrier fluids in seal supply circuits. The heat exchangers are made of helical, laser-welded finned tubes. The cooling medium is ambient air. It is important, therefore, for WEL heat exchangers to be installed in well ventilated places indoors or, ideally, outdoors. There is a choice of three different basic versions of the WEL6 range as well as being supplied fully assembled together with valves, base frame and other system components.

Advantages

  • Operating limits up to 44 bar / 260 °C
    (638 PSI / 500 °F) (tube side): suitable for a wide range of demanding operating conditions.
  • Can be completely vented and drained
  • Seamless pipes
  • Stainless steel 316/316L: high resistance to corrosive media

Standards and approvals

  • API 682 / ISO 21049
  • API 682 4th ed. Cat. 2/3 - 1CW-FL

WEF6 Water cooler

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).
