When practical requirements in terms of mobility and flexibility are high, but applications require the use of cryogenic fluids, the most suitable solution is the dewar. Dewars enable cryogenic liquefied gas to be stored long-term, under pressure or at atmospheric pressure, in very small quantities varying from a few litres to 1 m³.
Cryogenic tanks make it possible to store large quantities of gas in cryogenic form. Basically, they are made up of two containers, one fitted inside the other. In this way a cavity is formed isolating the gas from the external environment. Depending on requirements, the product can be drawn off in gaseous form or left liquid.
