Falling Film Evaporators: Principles Applications Alaqua

A falling film evaporator is a type of heat exchanger that uses a shell and tube design to evaporate heat-sensitive liquids. The feed is pumped into the evaporator from the top. It’s then uniformly dispersed throughout the heating tubes of the device. While partially evaporated, the liquid flows through tubes, forming a thin layer on the tube ...
