Advantages of Dewar:1.The storage pressure is low, and the multi-level safety protection device is installed, which has better safety and simple and reliable operation.
2.Large storage capacity, the gas storage capacity of a hexagonal gas cylinder is equivalent to nearly 30 cylinders of gas (oxygen, nitrogen, argon). Therefore, the storage space can be reduced, the bottle changing operation can be reduced, and the work efficiency can be improved. For centralized gas supply in pipelines, bus investment can be reduced.
3.The cylinder is clean and the supply gas purity is higher. Because the liquid gas is directly vaporized and supplied, it avoids the hidden quality hazards caused by secondary pollution due to many links in the process of filling, transporting and using the cylinder gas. Usually the output oxygen purity is ≥99.2%, nitrogen purity ≥99.999%, argon purity ≥99.995%, carbon dioxide purity ≥99.9%.
