500L Vertical Liquefied Nitrogen Liquid Oxygen Cryogenic Tank

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.

Dewar tanks can serve a variety of purposes:

◆Direct gas supply at the work site, and its use form is similar to that of compressed gas cylinders;

◆Small and simple pipeline centralized gas supply;

◆Cryogenic liquid use, etc.

Advantages of Dewar tanks:

◆The storage pressure is low, multi-level safety protection device is set, the safety is better, and the operation is simple and reliable.

◆Large storage capacity, the gas storage capacity of a hexagonal gas cylinder is equivalent to nearly 30 cylinders of cylinder gas (oxygen, nitrogen, argon). Therefore, the storage area can be reduced, the operation of changing bottles can be reduced, and the work efficiency can be improved. For the centralized gas supply of pipelines, the investment in busbars can be reduced.

◆The bottle body is clean and the purity of the supplied gas is higher. Because the liquid gas is directly vaporized and supplied, it avoids the potential quality hazards caused by secondary pollution due to many links in the process of cylinder gas filling, transportation and use. Usually output oxygen purity ≥99.2%, nitrogen purity ≥99.999%, argon purity ≥99.995%, carbon dioxide purity ≥99.9%.
