ABSTRACT:
In a vapor degreasing apparatus solvent vapor provided by a boiling sump is subjected to further heating for producing superheated solvent vapor to which a workpiece in the process of being cleaned is exposed. The superheated solvent vapor raises the temperature of the workpiece in order to minimize solvent adhering to the workpiece surface as the workpiece is removed from the apparatus to ambient. Further heating is achieved by heating means interposed in the natural convection flow path of the solvent vapor provided by a boiling sump to a vapor zone area in the degreasing apparatus.
