Wiped film evaporator WFE

processfor liquids

A Wiped Film Evaporators (WFE) is a thin film evaporator used to separate liquids through their differences in volatility through evaporation. It is a problem solver for difficult applications, such as: Heat sensitive products Highly fouling applications Viscous products High boiling point products For most WFE applications (fats, oils, nutraceuticals, polymers, resins, adhesives, biodiesel, oil re-refining, glycerin, flavors & fragrances etc.) alloy construction is suitable (Evaporation & distillation systems/ Wiped film evaporators). However, some processes in the chemical industry require the evaporative separation that the Pfaudler WFE provides, but are corrosive and also require the Glass-Lined (Glasteel®) construction that Pfaudler provides. A typical Glass-Lined (Glasteel®) WFE is similar to our alloy WFE design and has a jacketed shell, rotor, distributor and wipers; however, the shell is glass-lined steel (with carbon steel heating jacket), the rotor is glass-lined steel, and the wipers are PTFE. Pfaudler’s engineers design and supply Wiped Film Evaporators (WFEs) as part of a complete system. For optimal performance, they will address all design aspects, from simple utility flow requirements to complete vacuum system integration. Pfaudler focuses on providing the most efficient and reliable overall system to achieve optimal performance from your WFE.
