WFE Series Rotating Scraper Thin Film Evaporator for Heat-Sensitive Materials

The WFE series high-efficiency rotating scraper thin film evaporator is designed for heat-sensitive materials, featuring models from WFE-0.2 to WFE-10. This advanced evaporator forces feed material into a thin film using rotating scrapers and performs falling-film evaporation under vacuum conditions.

Key performance characteristics include high heat transfer coefficient, superior evaporation intensity, minimal residence time, and extensive operating flexibility. These features make it particularly suitable for evaporation concentration, degassing, desolvation, distillation, and purification of heat-sensitive materials, high-viscosity substances, and easily crystallized materials containing particles.

The WFE series finds extensive application across multiple industries including chemical, petrochemical, pharmaceutical, pesticide, daily chemical, food, and fine chemical sectors.
