Usually liquefied gases (oxygen, argon, nitrogen, hydrogen, and helium) at -150°C or lower, cryogenic tanks are used to hold liquids at extremely low temperatures. Additionally, they are used to store gases that can withstand greater temperatures, like liquefied natural gas.

Cryogenic tanks require a unique design in order to maintain extremely low temperatures. They each have an inner and an outer flask. Insulating material is placed between the flasks and is vacuum-separated from it. Cryogenic tanks need to be handled carefully because the flasks are only joined at the neck. There should be no bumps, vibrations, or tripping hazards. Otherwise, the insulation can be damaged, rendering the tank useless.

Pressurized and unpressurized cryogenic tanks are both possible.

For the storage and transportation of gases or liquids at extremely low temperatures below -150C, pressurised tanks are closed containers. They are made up of an outer vessel, an interior pressure vessel, insulation, and one or more necks with valves, flanges, or unions. The most popular pressurised tank sizes are 120 and 230 litres; these tanks are large and hefty. They are suggested for establishments like gyms, spas, and clinics that host a greater volume of daily sessions.

Dewar tanks without pressurisation are more manageable and compact. They provide extremely effective cryogenic liquid storage while being light and taking up little room. This kind of cryogenic tank is suitable for research institutes or small businesses that serve around 10 consumers each day.

Both models are compatible with Cryomed’s cryosaunas. It is only possible to use non-pressurized tanks with local cryogenic equipment.
