ABSTRACT:
An immersion type metal degreaser for use with relatively low boiling fluorocarbon solvents or azeotropes thereof in which liquid solvent is boiled and vaporized in the degreaser by a heater immersed in liquid solvent which constitutes the condenser section of a compression-expansion refrigeration system and in which solvent vapors within the metal degreaser are confined within the degreaser by being cooled and condensed by means constituting the evaporator section of the refrigeration system. An adjunct of the cooling system maintains a portion of the liquid solvent within which ultrasonic units are immersed at the optimum temperature thereof.
