The Tubular Falling Film Evaporator FFE is the right solution to
concentrate streams containing a small amount of suspended solids,
low-medium viscous fluids and heat sensitive products.
It is
particularly suited to energy saving multiple-effect (ME) evaporation,
Thermal Vapor Recompression (TVR) or mechanical vapor recompression
(MVR) arrangement due the very small operating temperature difference
between heating medium and process side ("driving force").
In a
multi-stage system, Falling Film Evaporators can be used in combination
with Thin Film Evaporators/Dryers or with Forced Circulation
Evaporators/Crystallizers.
