Abstract:
A system for converting liquid cryogen from a source into a pressurized cryogenic gas comprising:a. a pressure pod in communication with the source so that liquid cryogen is received therefrom; b. means for ambient heating of the liquid cryogen in the pressure pod; c. a heat exchanger having in inlet and an outlet, both in communication with the pressure pod; d. an automated valve in circuit between the inlet of the heat exchanger and the pressure pod, said automated valve set to open when the pressure within the pressure pod exceeds a first predetermined level due to ambient heating of the liquid cryogen therein; whereby pressurized cryogen gas is produced within the pressure pod by ambient heating of the liquid cryogen therein and vaporization of the liquid cryogen by the heat exchanger when a pressure within the pressure pod exceeds the first predetermined level.
