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.

    VTA − plant design at its best

    VTA delivers package units in laboratory, pilot and industrial scale. Package units are skid mounted, pre-assembled systems for wiped film
    and short path distillation, rectification and thin film drying.
    All core components, like evaporators, condensers, vessels and piping, are manufactured in modern manufacturing facilities by highly qualified
    workers either by VTA or within the STREICHER group.
    All engineering services are performed entirely inhouse at VTA. By minimizing the interfaces, a smooth project execution is ensured.
