The space between the inner and outer vessel, containing several inches of insulating material maintained in a vacuum. The vacuum and insulating material help to reduce heat transfer and thereby reduce the boil-off of the liquid oxygen, liquid nitrogen or liquid argon stored within the vessel.

What is cryogenic tank?

Cryogenic liquid containers, also referred to as liquid cylinders, are double-walled vacuum vessels with multilayer insulation in the annular space. They are designed for the reliable and economic transportation and storage of liquefied gases at cryogenic temperatures, typically colder than –130°F (–90°C).

What is a cryogenic tank used for?

Cryogenic tanks are used for the storage of cryogenic liquids. Cryogenic liquids are typically liquefied gases at -150 °C or lower. Common products include oxygen, argon, nitrogen, hydrogen, and helium.
