Cryogenic tanks

The right nitrogen feed system for your cryotherapy machine

Cryogenic tanks are specially engineered for storing liquefied gases at temperatures of −150°C and below. Their double-wall design – with vacuum between the inner and outer flasks – minimizes heat transfer and maintains the ultra-low temperatures required for cryotherapy applications.

In cryotherapy, cryogenic tanks serve for transporting, storing, and supplying liquid nitrogen to cryochambers and local cryotherapy devices, enabling them to reach −130 °C and lower.
