A pressurised tank is made up of an exterior vessel, insulation, an interior pressure vessel, and one or more necks with valves, flanges, or unions. The cryogenic liquid is pumped into and dispensed from the valves, and a pressure-control valve with a fragile rupture-disk serves as a backup safety measure.

The cryosauna’s pressurised tank remains outdoors. It is connected with a hose that your nitrogen supply need to give (if not, you can buy a 2-meter hose from us). When a session begins, a cryogenic valve that controls nitrogen flow opens at regular intervals, forcing nitrogen through the hose and into the cryosauna under pressure. The tank’s pressure should range from 1.5 to 2.5 bars.
