ABSTRACT:
Vapor degreasing apparatus comprising a tank having in its lower part a heatable reservoir for a solvent for fats, oils, lubricants or the like, and having, above said reservoir, a vapor space adapted for introducing therein metal articles or machine parts to be degreased. Cooling water piping is provided in the upper part of the tank, said piping comprising a section which functions as a heat exchanger for incoming heat released during the vapor-liquid conversion of the solvent while forming a vapor escape barrier for retaining, through condensation, the solvent vapor, said piping also comprising a section which functions as a heat exchanger for outgoing heat to the ambient air. A gutter is provided below the heat exchangers for catching the condensate, a pump is connected to the cooling water piping for circulating the water and air exhaust means is provided in the uppermost part of the tank for exhausting threads of vapor, if any, passing the vapor escape barrier, and for cooling that section of the cooling water piping which functions as the heat exchanger for said outgoing heat to the ambient air. A water jacket is provided in which the cooling water piping which functions as the heat exchanger for incoming heat is positioned. The cooling water piping is formed as a closed circuit without direct communication between the water coolant and the air of the outgoing heat exchanger.
