  • Vapor degreaser
    Patent number: 5945016
    Abstract: An improved vapor degreaser with a tank having a conventional lower portion with a solvent which is heated and cooling coils which largely combine the solvent vapor zone to a solvent vapor level. An upper tank portion rests above the conventional tank and has a second set of cooling coils. A first cover is placeable between the conventional tank and the upper tank portion. A second cover is placeable over the upper tank portion to provide a vapor degreaser with a much lower chance of any vapors escaping the degreaser.
