Product introduction: vertical Dewar bottle self-pressurization liquid nitrogen tank

Low temperature Dewar bottle products, is the use of advanced technology and technology, the production process of each link in the scientific, strict quality assurance system control. It is composed of stainless steel inner and outer tank, high vacuum insulation interlayer, built-in vaporizer, valve pipeline system, etc. It is used to store and use cryogenic liquefied gas products (liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquid carbon dioxide) and can automatically provide continuous gas or cryogenic liquid nitrogen.

Product introduction:

Dewar bottle, a stainless steel pressure vessel with super vacuum insulation, is designed for storage, transportation and use of liquid oxygen, liquid nitrogen, liquid argon or carbon dioxide. For reliable and economical transportation and storage of cryogenic liquid gas, as well as local storage and supply of cryogenic liquid gas in a wide range of applications. And liquid nitrogen.

Dewar bottle has two main advantages: first, it can hold a large amount of gas at relatively low pressure compared with compressed gas cylinder. The second is that it provides an easy to operate cryogenic liquid source. Third, two-way output, one output liquid nitrogen gas, the other output liquid nitrogen, can provide low-pressure refrigeration liquid liquid nitrogen for the equipment. Gas liquid two-phase use.

Various uses of Dewar are available:

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

Small and simple centralized gas supply pipeline;

Low temperature liquid use, etc.

Advantages of Dewar bottle:

Low storage pressure, multi-stage safety protection device, better safety, and simple and reliable operation.

A large volume of nitrogen and oxygen storage cylinders. Therefore, the storage area can be reduced, the bottle changing operation can be reduced, and the work efficiency can be improved. For centralized pipeline gas supply, it can reduce bus investment.

The bottle body is clean and the purity of supply gas is higher. In the process of transportation, the gas is easy to be polluted due to the secondary gas supply. In general, the purity of oxygen, nitrogen, argon and carbon dioxide are 99.2%, 99.999%, 99.995% and 99.9%, respectively.

High gas utilization rate: residual pressure must be reserved after each use of cylinder gas, and liquid gas supply of hexagonal cylinder can avoid any waste and reduce gas cost.

The weight of hexagonal cylinder is about 116kg, and the total weight after filling with liquid gas is about 300kg, while the total weight of compressed gas of 30 cylinders with the same amount of gas is nearly 2000 kg. Therefore, the auxiliary cost of transportation and manual handling can be greatly reduced.

It has automatic pressurization control, saving circuit, built-in carburetor, pressure and liquid level indicating device, with high integration.

Use advanced technology to improve the production environment and corporate image.

It does not need any kinetic energy and is not affected by power failure and water cut-off. It can work all day long.

Bande liquid nitrogen tank series products provide one year free after-sales service
Five year vacuum warranty.
