ABSTRACT:
A retrofit manifold, system and process for converting a solvent vapor degreaser to an aqueous solution degreaser is provided for an efficient and environmentally safe method for removing contaminants from workpieces, manufactured articles and other parts. A uniquely designed agitation manifold is fitted at the back wall of the wash tank. Unclean workpieces are submerged in hot aqueous solution in the wash tank and are positioned in the wash tank in front of the agitation manifold. A plurality of nozzles arranged at each section of the manifold spray aqueous solution at the workpieces. Oil based contaminants separated from the workpieces are collected at the surface of the aqueous solution and exited from the tank along with a quantity of aqueous solution. The contaminants are removed from the system and the aqueous solution is recycled back into the wash tank.
