The vessel is constituted by an inner container, where the cryogenic fluid is in liquid state, built in stainless steel, with resilient and austenitic materials, resistant to the lowest operating temperature (-196ºC), and a carbon steel shell that it supports an external pressure of 1 bar. The thermal insulation is carried out with filling of the chamber between the two tanks with insulating material and a high vacuum, it also includes absorbent material for greater stability of the vacuum, the effective thermal insulation minimizes product losses and allows a long storage at low temperature for these liquefied gases.
