ABSTRACT:
A cryogen supply system for supplying either gaseous state cryogen or liquid state cryogen. The cryogen supply system includes a thermally insulated fluid container for holding a volume of cryogenic liquid. A gas inlet port is formed in the fluid container so that gas from an external source can be introduced therein. Inside the fluid container is a cooling module having a gas inlet opening for receiving gas introduced into the fluid container. The gas that flows into the gas inlet opening flows into a heat exchanger located at the base of the fluid container. The heat exchanger is connected to a manifold that, in turn, is connected to an outlet line. A liquid inlet line, having a liquid inlet opening in the base of the fluid container is also connected to the manifold. Gas flow from the heat exchanger to the manifold and from the liquid intake to the manifold is controlled by appropriate valve means. The outlet line is connected to a heating module in which the fluid flowing through may be heated to a selected temperature. The pressure of the gas introduced into the fluid container forces gas into the inlet line and the heat exchanger, where it is cooled to a temperature at or just above that of the cryogenic liquid, and also forces cryogenic liquid into the liquid inlet line.
