When oxygen is cooled to a very low temperature

(around 300 degrees below zero Fahrenheit), it

becomes a liquid. In the liquid form, large amounts

of oxygen can be stored in a container at quite low

pressure. This provides not only a large storage

capacity, but also allows for filling and refilling of

a smaller unit from the large unit.

To remain in the liquid form, the oxygen must

continue to be kept very cold. Therefore, the units

in which the liquid oxygen is stored are insulated

canisters similar to large Thermos

bottles. As the

liquid oxygen leaves the container, it warms up to

room temperature and becomes a gas again.

A liquid oxygen system usually includes two units:

stationary reservoir

and a

portable unit.
