Abstract:
1. A method for transferring gas to a device comprising the steps of: transferring a cryogenic fluid from a supply container into a vessel; after the cryogenic fluid is transferred into the vessel, transferring heat from the device to the cryogenic fluid in the vessel with a heat transferring system in contact with the vessel and the device to vaporize the cryogenic fluid into a cryogenic gas within the vessel; opening an entrance valve between the supply container and vessel and transferring more cryogenic fluid from the supply container into said vessel when at least one of the temperature or the pressure of the gas within the vessel is over a set-amount; and transferring the gas from the vessel to a device; wherein said cryogenic fluid and said cryogenic gas are not vented to atmosphere or to the supply container.
