Falling Film Evaporators (FFE)


We are Manufacturer, Supplier of Falling Film Evaporators, FFE, Falling Film Tubular Evaporators and our set up is situated in Pune, Maharashtra, India.

A Falling Film Evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger. It is also known as Falling Film Tubular Evaporators.

The Falling Film principle requires an even distribution of the feed liquid. To achieve this distribution one or more distribution trays are located in the top head of the evaporator over the complete tube sheet.

Our proven distribution devices make sure that the inner surface of each individual tube is properly wetted.

The liquid film moves down the tubes by gravity force. Heat applied through the tube wall effects boiling-off the light fraction from the film. The picture shows a co-current operating evaporator with vapour and liquid leaving the bottom of the evaporator into the separator vessel.


  • Falling Film Evaporator is suitable for high viscous liquids because the flow of vapor film assisted by gravity.
  • The liquid is not over heated during passage and heat transfer coefficients are high even at low boiling temperature.
  • Highly acidic and corrosive feeds can be concentrated using impervious graphite tubes rubber lined vapor heads.
