COMP offers a complete range of Rising Film Evaporators of both short and long tube design.
In Rising Film Evaporator, due to the ascending force
of the vapour bubbles, which are produced during boiling, the
liquid and vapours flow upwards in a parallel flow.
Simultaneously the vapour quantity also increase thereby forming
a "Climbing" film on the walls of a tube. Due to this
there is a high turbulence in the liquid and these evaporators
are advantageous for heat sensitive, highly viscous and
moderately scaling liquids.
The temperature difference in the rising film evaporators
should be high between the heating chest and boiling chamber to
ensure the circulation and formation of a climbing film.
These evaporators are flexible enough to be converted to
