What Are the Advantages of Horizontal Liquid Dewar Cylinder？

Dewar tanks are stainless steel pressure vessels with super vacuum insulation, designed for storage, transportation and use of liquid oxygen, liquid nitrogen, liquid argon or carbon dioxide. Manufactured to DOT4L standards, these vessels are used for reliable and economical transport and storage of cryogenic liquid gases, as well as on-site storage and supply of cryogenic liquid gases in a wide range of applications.

Dewars have two main advantages:

1. Compared with compressed gas cylinders, it can hold a large amount of gas at a relatively low pressure.

2. It provides a low-temperature liquid source that is easy to handle.

Due to the firmness and reliability of the Dewar tank, its long retention time, and its own gas supply system, its built-in vaporizer can continuously output normal temperature gases (oxygen, nitrogen, argon) with a flow rate up to 9.2m3/h, and the maximum constant output pressure of the gas can reach 1.2 MPa (medium pressure type)/2.2 MPa (high pressure type), fully meet the gas consumption requirements under normal circumstances. If the user uses a large gas flow, multiple Dewar tanks can be connected in parallel or an external vaporizer can be installed to meet the gas supply requirements. By installing an external vaporizer, the maximum output flow of a single Dewar tank can reach 30m3/h.

Product Description

The cryogenic products normally found in liquid containers are liquid nitrogen (LIN), liquid argon (LAR), liquid oxygen (LOX), and liquid helium (LHE). Carbon dioxide and nitrous oxide are also available as refrigerated liquids in similar containers.

The cryogenic liquid cylinders we produced adopted the advanced techniques and the whole production process is under the strict quality-guarantee control system. It can be applied to store, transport the cryogenic liquefied gas products (liquid oxygen, liquid argon, liquid nitrogen, liquid natural gas, liquid CO2, etc),and it can automatically provide continue gases.


Although these containers are well insulated, heat will continuously leak into the product, due to the extremely large temperature difference between the cryogenic liquid and the ambient environment. The heat leak will cause some vaporization to occur. Vaporized product, if not used, will collect in the vapor space above the liquid and build pressure.This is referred to as head pressure. The head pressure will build in the container and periodically vent via the pressure relief valve. Vaporization rates will vary and may be as low as 0.4% or as high as 3% of the container's volume per day.This is a normal and safe function of the container.
