What is a Thin Film Evaporator Thin Film Evaporators

Evaporation is the process of changing a liquid into a gas. 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.
