Thin Film Evaporator


Complex tasks require special process Solutions - We concentrated our expertise from process Engineering and equipment development to develop highly specific Thin Film Evaporators. The perfect solution for demanding applications in thermal Separation.

Special Solutions for demanding tasks

The Thin Film Evaporator made of high quality materials provides the highest performance and allows even to separate sensitive products in small quantities.

Depending on the manufacturing and product requirements, we develop for each of our clients tailor-made distillation modules. Their heartpiece - individually selected evaporators with perfectly matching rotor types.


The Thin Film Evaporator consists of a cylindrical, with mechanical precision machined heating surface with external heating and an internal rotor. The mixture is spread on the apparatus head lying rotating distribution system on the circumference and flows the externally with steam or thermaloil heated/external) wall down. In this case, a uniform distribution and a liquid film is produced mechanically by a wiping elemint. Vortex forms with highly turbulent heat transfer zones, which provide in addition to the achieved good heat transfer for a constant renewal of the heating surface-contacting product on the wiper blades. The result is a gentle evaporation process, which ensures the product quality through shortest possible contact to the heating element and thus under minimized thermal pressure.


  • Individual selection and adjustment of the optimum rotor type

  • High evaporation rates

  • Short residence time of the product

  • Gentle evaporation

  • Good heat transfer even with highly viscous or heavily polluted media

  • No additional lubrication required

  • Reduced maintenance

  • Shorter downtime and assembly time for maintenance / inspection

  • No corrosion by using suitable materials


Our Thin Film Evaporators can be used both, for concentration and for purification of recyclables. Exactly tailored to your needs, the devices are particularly suitable for the following performance areas:

  • Concentrating of temperature-sensitive products

  • Concentrating of viscous media

  • Concentrating of structurally media

  • Distilling off low boilers from recyclables

  • Purification by distillation of products from value-boiling components

  • Mass transfer through the thin, constantly renewed film

  • Special applications such as e.g.: reboiler for rectification

  • Drying
