An Agitated Thin Film Evaporator (ATFE), also known as Thin Film Evaporator (TFE) or Wiped Film Evaporator (WFE), consists of a jacketed shell precision machined from inside and a rotor having blades that maintain a close clearance from the shell.
A feed distributor at entry point distributes the liquid in a thin film on the heated wall. The high speed rotor further spreads and intensely agitates the film as it flows down. The generated vapors flow countercurrently and get cleaned by an integrally mounted entrainment separator.
The processing is completed in a few seconds.
'Our high viscosity units can handle products with viscosities of several million centipoise!'


  • Residence time of a few seconds with a narrow spread, an important feature for heat sensitive products
  • Required evaporation is achieved in a single pass, avoiding product recircultion and possible degradation
  • Scale formation on the heat transfer surface is reduced due to the intense agitation of the liquid film
  • Excellent turn down capability
  • Low product holdup, ideal for hazardous applications
  • Operating pressure as low as 1 mbar and operating temperature up to 400 0C
  • Special designs for clean room applications


  • Vacuum distillation of bulk drugs, intermediates, fine chemicals, glycols, used lubricating oils, fatty acids and their derivatives, rubber chemicals, amines and esters
  • Concentration of bulk drugs
  • Processing of oleoresins, enzymes, plant extracts, milk products, juices and sugars
  • Stripping of silicone oils, pesticides, plasticizers and monomers
  • Recovery of contaminated solvents and products from residues
  • Paraformaldehyde and high viscosity applications like stripping of polymer melts
  • Purification of biodiesel and recovery of glycerin
  • Recovery of products from residues
  • Recovery of solvents from contaminants
  • Pre-concentration before ATFD or SPDU

We have well equipped Pilot Test Centres in Nashik, India & Geleen, the Netherlands.
