Abstract: An improved freezer and plant gas system that harnesses the cooling properties of the plant gas evaporator to facilitate energy and cryogen savings, as well as the automation and optimization of a plant thermal processing system. The freezer preferably includes an internally mounted evaporator sized to meet the gas requirements of the plant processes requiring inert gas. By evaporating the plant gas in the freezer, the freezer can be remotely located from the liquid cryogen source while still making liquid cryogen available when called for during a cryogenic treatment process metal or other materials. In addition, by evaporating in the freezer the freezer is able to harness the cooling properties of the evaporator to pre-cool the freezer and material prior to use of liquid in the cooling cycle. Alternatively, a liquid load basket is adapted to economically thermally treat materials in a deep cryogenic treatment.
