Uses and characteristics of vertical Dewar flasks

Dewar is a pressure vessel used to transport and store cryogenic liquids such as liquid oxygen, liquid nitrogen, liquid argon, liquid carbon dioxide, and LNG. Gas cylinders can be used to supply liquid or gaseous gas.

Dewar flask is easy to use, safe and reliable, economical and durable. The specific features are as follows:
(1) The support system of the cylinder liner is made of stainless steel, which can achieve the purpose of low heat loss and high strength.

(2) Dewar flasks are easy to use and can be operated independently by a single person.

(3) Dewar flasks are used to store pure cryogenic liquids. (4) Large storage capacity. The gas storage capacity of a DP175 gas cylinder is equivalent to more than 18 times the gas storage capacity of a standard high-pressure gas cylinder.

(5) The internal pressure of the Dewar bottle will rise after it is filled with liquid. The gas bottle has a high-performance insulation system, and its pressure rise rate is low. Under normal circumstances, there is no need to reduce the pressure through a safety valve.

(6) The built-in supercharger and vaporizer in the pressure vessel can realize continuous supply of gas or liquid, and no external vaporizer is required in the case of design usage.
