1. Introduction Cryogenics is the science of production and application of artificial cold at very low temperatures. For a long time, the temperature range of cryogenics was not strictly defined, until the 13th IIR International Congress of Refrigeration (held in Washington DC in 1971) adopted a universal definition of "cryogenics" and "cryogenic" by …

Uses of refrigerated tanks. Refrigerated tanks are used to store liquefied gases that go from a range of boiling points from between -126.6°C a -1.1°C (-260°F a +30°F) and thus require cryogenic temperatures to be safely and efficiently stored. This includes ethylene, butane, refrigerated LPG and other substances mentioned above, for …
