Cryogenic containers

What are cryogenic containers?

Portable cryogenic containers, also known as dewars, are portable containers for cryogenic liquids manufactured with double walls and vacuum-insulated. They are used to supply oxygen, nitrogen, and liquid-state argon and have a capacity of up to 1,000 litres.

The interior lining is made of stainless steel, while the exterior can be carbon steel or stainless steel. Because they are vacuum-insulated, they do not transfer heat and maintain an adequate temperature.

Dewars or cryogenic packages rely on devices that keep pressure within the pre-established limits. They vaporise liquid when pressure drops and can release gaseous state gas when pressure increases. They can supply their content both in a liquid or gaseous state by opening the appropriate valve. They are capable of supplying gas in a stable and continuous flow.

Portable cryogenic containers have relief valves and rupture discs inside the tank to ensure user safety.

The major advantages of cryogenic containers are:

• Time savings. Avoids ongoing cylinder replacement.
• Space savings. An oxygen dewar takes up less space than 12 cylinders with the same volume of gas.
• Gas savings. Less residual gas is wasted because these cryogenic containers can be emptied almost completely.

Available capacities go from 30 litres up to 600 litres, depending on the needs of each client.
