Dec 08, 2021 Falling film evaporators are also becoming much more efficient. The heat removed for the solvent in the condenser can be recycled to heat the heat transfer liquid and create a closed loop system. Recycling energy in this way is a clever solution to keep the costs of operating a falling film unit down.

What is a Thin Film Evaporator Thin Film Evaporators

Evaporator equipment is typically designed to produce a thin film on a heated surface so that solvents will volatilize quickly and efficiently. Condensation is the process of changing a vapor or gas into a liquid. The liquid in this case is called a condensate. The term thin film is also applied to a condenser because as condensable vapor gas ...
