Claim 0:
1. A cryogenic vaporization system, the system comprising:
a first bank of ambient air vaporizer units configured for vaporizing a liquid cryogen and outputting a stream of cryogenic vapor;
a second bank of ambient air vaporizer units configured for vaporizing the liquid cryogen and outputting another stream of cryogenic vapor, the second bank of ambient air vaporizer units connected in parallel with the first bank of ambient air vaporizer units;
a third bank of ambient air vaporizer units configured for receiving the liquid cryogen and outputting yet another stream of cryogenic vapor, the third bank of ambient air vaporizer units connected in parallel with the first bank of ambient air vaporizer units and the second bank of ambient air vaporizer units; and
a plurality of control valves configured to switch provision of the liquid cryogen between the first, second, and third banks of ambient air vaporizer units such that two of the first, second, and third banks of ambient air vaporizer units vaporize the liquid cryogen, while one of the first, second, and third banks of ambient air vaporizer units is idle.
