Vapor degreasing with chlorinated solvents

Degreasing is an essential part of the modern production process, particularly in industries fabricating or assembling metal parts including aircraft, appliance, automotive, electronics, and railroad manufacturers. Vapor degreasing is ideal for reaching into small crevices in parts with convoluted shapes to remove stubborn soils. Parts degreased in chlorinated solvent vapors come out of the process dry; there is no need for an additional drying stage, as in aqueous and semiaqueous processes. The traditional vapor degreasing process is carried out in either a batch or an inline degreaser. The degreasing process may be supplemented by adding a spray lance to the open-top degreaser so that hard-to-remove soils can be flushed offby the operator. The monorail conveyorized degreaser uses a straight-line conveyor to carry parts into the degreaser, lower them into the vapor zone, raise them into a cooling zone, and finally out of the degreaser.
