Falling Film Evaporator

In the falling film evaporators, the heating media gets circulated through the shell side of the heat exchanger. The process fluid passes through the tube side of the evaporator, and energy gets transferred from the heating media into the product. Then, a portion of the product gets vaporized.
• A thin film of liquid on the tube surface ensures a very low liquid circulation requirement and high heat transfer coefficients.
• Moreover, the term “falling film” basically refers to the liquid firm that comes down the tubes and is the source of the heat exchanger’s name.
