Abstract: A vaporizer system includes a defrosting function along with the ability to convert liquefied gas to a use gas. The vaporizer system includes first and second vaporizers and piping that transfers fluid from an inlet port to an outlet port with a portion of the piping being between the first and second vaporizer. The system also includes a trim heater and a number of valves for regulating flow of the fluid through the transfer piping. The valves may be placed in a first configuration where vapor from the first vaporizer is heated and directed to the second vaporizer so that the second vaporizer is defrosted and a second configuration where vapor from the second vaporizer is heated and directed to the first vaporizer so that the first vaporizer is defrosted.

Abstract: A system for dispensing cryogenic liquid includes a container defining an interior with a partition dividing the interior into primary and reserve chambers. Cryogenic liquid within the primary chamber is separated from cryogenic liquid in the reserve chamber. The partition provides a headspace cornrnurrrcation passage. A primary pressure building circuit has an inlet selectively in liquid communication with the primary chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers. A reserve pressure building circuit has an inlet selectively in liquid communication with the reserve chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers. An equalizing circuit is selectively in liquid communication with the primary and reserve chambers. A dispensing line is selectively in liquid communication with the primary chamber.

Abstract: A system for dispensing cryogenic liquid includes a container defining an interior with a partition dividing the interior into primary and reserve chambers. Cryogenic liquid within the primary chamber is separated from cryogenic liquid in the reserve chamber. The partition provides a headspace communication passage so that the headspaces of the primary and reserve chambers are in fluid communication with one another. A primary pressure building circuit has an inlet selectively in liquid communication with the primary chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers. A reserve pressure building circuit has an inlet selectively in liquid communication with the reserve chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers of the tank. An equalizing circuit is selectively in liquid communication with the primary and reserve chambers. A dispensing line is selectively in liquid communication with the primary chamber.
