FIELD: vessels for containing or storing compressed, liquefied or solidified gas, particularly ones with thermal insulation. ^ SUBSTANCE: cryogenic device has vessel with coolant, drainage and filling pipelines and adsorbent. Vessel is made as Dewar flask provided with additional shell having perforated bottom so that inter-wall cavity is formed. The cavity defined by additional shell communicates with filling pipeline and is provided with electric heater. The inter-wall cavity has level indicator linked with electric heater and communicates with drainage pipeline. ^ EFFECT: increased efficiency. ^ 1 dwg |
