Abstract:
A process for vapor degreasing of parts comprising the steps of:a. loading the parts to be degreased into an atmospheric tight chamber; b. purging the chamber to remove any oxygen therein by means of an inert gas or by pulling a vacuum and backfilling with an inert gas; c. introducing the degreasing fluid into the chamber and spraying the degreasing fluid over the parts in the chamber; d. stopping the flow of degreasing fluid into the chamber when a small amount of the degreasing fluid has collected in the bottom of the chamber; e. heating the lower part of the chamber to vaporize the degreasing fluid; f. when the vapor level has risen to the top of the chamber, stopping the heating and draining remaining degreasing fluid from the chamber; g. removing the vapors from the chamber by purging the chamber with an inert gas; and h. opening the chamber and removing the parts therefrom.
