The Dewar bottle has two main advantages

    The first is its ability to hold large volumes of gas at relatively low pressures compared to compressed gas cylinders.
The second is that it provides a source of cryogenic liquid that is easy to handle. Due to the robustness and reliability of the Dewar cylinder, its long retention time, and its own gas supply system, it can be used with its built-in vaporizer and continuous output of normal temperature gases (oxygen, nitrogen, argon) with a flow rate of up to 10 m3/h. The high constant gas output pressure of 1.2 MPa (medium pressure type) and 2.2 MPa (high pressure type) can fully meet the gas requirements under normal circumstances.

    The Dewar cylinder can be used for a variety of purposes: direct gas supply at the work site, similar to compressed gas cylinders; small and simple centralized gas supply by pipeline. Low temperature liquid use, etc.
