Cryogenic Tanks

To operate any Cryomed’s cryosauna, cryogenic tanks are needed. Such tanks are used to supply liquid nitrogen into the cryosauna, which cools it down to -130°C and lower.

Cryogenic tanks can be pressurized and non-pressurized. Cryomed’s cryosaunas are compatible with both types. With local cryogenic machines, only non-pressurized tanks are used.

Pressurized Tanks

Pressurized Tanks

A pressurized cryogenic tank is a closed container designed to store and transport liquids or gas at very low temperature below -150°C
Non-Pressurized Dewar Tanks

Non-Pressurized Dewar Tanks

Dewar vessels are specialized types of vacuum flasks designed for the transportation and storage of liquid nitrogen, argon, and oxygen

What Is a Cryogenic Tank?

Cryogenic tanks are containers designed for the storage of low-temperature liquids, usually liquefied gases at -150°C or lower. Common cryogenic liquids include oxygen, argon, nitrogen, hydrogen, and helium. Cryogenic tanks are also used for storing gases at higher temperatures, such as liquefied natural gas.

To keep very low temperatures, cryogenic tanks need to have special design. Typically, they have an outer flask and an inner flask. Between the flasks, there is insulating material separated by vacuum. The flasks are connected only at the neck, that is why cryogenic tanks need to be handled with care. Impacts, vibration, tripping over can ruin the insulation and make the tank unusable.

How the Non-Pressurized Tank Cryosauna Differs from the Pressurized Tank Cryosauna?

If you opt for the non-pressurized tank version, you get two 35-liter Dewar tanks in set with your cryosauna. You can buy additional Dewars, if needed, or choose 50-liter Dewars as an option.

If you go for the pressurized tank version, we do not provide such tanks in set, as it is cheaper and more convenient to rent them from a local liquid nitrogen supplier. Pressurized tanks are expensive, and you might need a bigger capacity vessel with time, if you have more customers and more sessions. Requirements for the tanks differ from country to country, too.

Our sales managers can help you choose the type the tank best suited for your business.

A cryogenic tank is a tank that is used to store liquids at very low temperatures, usually liquefied gasses (oxygen, argon, nitrogen, hydrogen, and helium) at -150°C or lower. They are also used for storing gasses at higher temperatures, such as liquefied natural gas.

The principle of work of pressurized and non-pressurized cryogenic tanks differs.

Non-pressurized Dewar tanks are rolled into a cryosauna for the time of the session. There is a pipe in the cryosauna which goes down into the Dewar to pump nitrogen steam into the cabin during a session.

A pressurized tank stays outside the cryosauna and is connected with a hose. Nitrogen flow is regulated by a cryogenic valve which opens at regular intervals when a session starts, with pressure pushing nitrogen through the hose into the cryosauna.

The price of a cryogenic tank depends on its type and capacity.

The capacity of pressurized tanks ranges from 60 to 300 liters. The most popular capacities are 120 liters and 230 liters.

Non-pressurized tanks can be with the capacity of 10-, 35- and 50-liters.

The price will vary depending on this. Please contact our sales team for the pricing on cryogenic tanks.
