Wiped Film Evaporator (WFE)

Wiped film evaporators (WFE or "wiffe") provide short residence time and open, low pressure drop configuration, allowing continuous, reliable processing of many heat sensitive, viscous, or fouling materials without product degradation.

Thin film evaporators quickly separate more volatile from less volatile components using indirect heat transfer and mechanical agitation of a flowing product film under controlled conditions. Either the vaporized component (distillate) or the concentrated component may be the product depending on the application.


  • 25 square foot capacity
  • 316 stainless steel construction
  • Short residence time of the feed liquid
  • Significantly lowered temperature due to high vacuum capability
  • Optimal efficiency in mass and heat transfer
