How does a pressure tank work?

Pressurized tank consists of an inner pressure vessel, outer vessel, insulation and one or two necks with the valves, flanges or unions. The valves are used for filling and dispensing the cryogenic liquid, and a pressure-control valve with a brittle rupture-disk for backup protection.

A pressurized tank stays outside the cryosauna. It is connected with a hose which should be  provided by your nitrogen supplier (if not, you can buy a 2-meter hose from us). 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 pressure in the tank should be between 1.5 and 2.5 bar.
