Thin-film evaporator V series

GLASS LINED THIN FILM & SHORT PATH EVAPORATORS Processing of corrosive or metal active products Highly corrosive products require special Cr-Ni base alloys or special construction materials such as titanium or tantalum for product wetted parts. On the other hand, some products are metal-active and do not allow metal contact. For processing heat-sensitive products at high vacuum and short residence times, VTA offers wiped film and short path evaporation technology with product contacting parts made of enamel (glass lined) and PTFE material. Often this is more economical than other special materials. Exceptions are hydrofluoric acid, compounds generating HF during the evaporation process and highly concentrated acids at high temperatures.
