Applications for Falling Film Evaporators

Falling film evaporators are used extensively in chemical process industry, food and paper industry. Due to the absence of static static head effect caused by liquid column as in other types of evaporators, evaporation can take place at very small effective mean temperature differences. The temperature diffference are tipically between 3 - 8C.
