Cryogenic Storage In Cryotherapy

Dewar tanks in cryotherapy are used primarily to supply nitrogen into cryogenic equipment during its operation. Another their function is transporting and storing liquid nitrogen with maximum safety and efficiency.

Dewar tanks we offer are compatible with Cryomed’s whole-body and local cryogenic equipment:

35-liter Dewar tanks come in set with the Dewar type cryosaunas and local cryogenic machines;
50-liter tanks are available optionally for cryosaunas and CRYOFAN CF-04;
10-liter Dewars are optional for CRYOFAN CF-04.

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.

They are not interchangeable, you cannot have one replaced with the other, and therefore, it is important from the very beginning to choose the one which will be more suitable for your needs.

Dewar tank is an ideal option for spa and beauty centers, healthcare facilities, and research labs because of its smaller dimensions and volumes, as well as low weight compared to big pressurized tanks. Most of the Dewar tanks are portable and lightweight, making it convenient to handle. For example, a tank with a capacity of 10 liters has an overall height of 53 cm, a diameter of 30.5 cm, and a weight of 13.4 kg when it's full.

Cryomed offers liquid nitrogen Dewar flasks with a 10-, 35- and 50-liter capacity. You can find all the dimensions and technical characteristics of the available tanks in the table.

Dewar tanks are rather portable and lightweight compared to pressurized tanks, they also don’t require much space. That’s why small cryo businesses like to use them.

The 10 liter Dewar tank has an overall height of 53 cm, a diameter of 30.5 cm, and a weight of 13.4 kg when it's full (empty weight is 5.4 Kg).

The 35 liter Dewar tank has an overall height of 72 cm, a diameter of 45.5 cm, and a weight of 45 kg when it's full (empty weight is 17 Kg).

The 50 liter Dewar tank has an overall height of 85.5 cm, a diameter of 49.5 cm, and a weight of 59.5 kg when it's full (empty weight is 19.5 Kg).

A dewar tank is a vessel with a vacuum space between a cold liquid and the outside walls of the vessel. One common type of dewar container is a thermos that you might use to keep drinks cold. Cryogenic dewars store, dispense or transport cryogenic gasses like liquid nitrogen, liquid oxygen, liquid helium, and liquid hydrogen. Its construction and thermal insulation ensure the temperature inside is low enough to prevent excessive loss of cryogenic liquids.
