Cryogenic cylinders was designed for high vacuum multi-layer winding insulation structure, the tank is used for storing cryogenic liquid, multilayer insulation materials was winded in the outer wall, so it has superior thermal insulation functions. Meanwhile, sandwich was evacuated to a high vacuum, all those can form a good insulating system.

These containers are manufactured according to the DOT4L standard for reliable and economical transportation and storage of low-temperature liquid gas, and in-situ storage and supply of low-temperature liquid gas in a wide range of applications. Due to the sturdiness and reliability of the Dewar tank, its long holding time, and its own gas supply system, the built-in carburetor can continuously output normal temperature gas (oxygen, nitrogen, argon) with a flow rate of up to 9.2m3 / h, and the gas constant output pressure reaches 1.2MPa (medium pressure type) / 2.2 MPa (high pressure type), fully meet the gas requirements under normal circumstances. 

If the user has a large gas flow, multiple Dewars can be connected in parallel or an external carburetor can be installed to meet the gas supply requirements. By installing an external carburetor, the output flow of a single Dewar can reach 30m3 / h.
