What is a dewar tank?

A dewar tank, also known as a Dewar flask or simply a Dewar, is a specialized container used for storing and transporting cryogenic liquids, such as liquid nitrogen, liquid oxygen, or liquid helium. It is designed to keep these substances at extremely low temperatures, close to or at their boiling points, which can be as low as -196 degrees Celsius (-321 degrees Fahrenheit) for liquid nitrogen.

Why is it called a dewar?

The Dewar tank is named after its inventor, Sir James Dewar, a Scottish physicist and chemist who developed the container in the late 19th century. The primary purpose of a Dewar tank is to provide excellent thermal insulation to prevent the cryogenic liquid inside from rapidly evaporating.

Cryogenic Liquid Nitrogen Dewars Structure

The construction of a Dewar tank usually consists of two main parts:

Inner Vessel: This is a double-walled container with an inner and outer chamber. The inner chamber holds the cryogenic liquid, while the space between the inner and outer walls is usually evacuated or filled with a vacuum to minimize heat transfer through conduction and convection.

Outer Jacket: The outer jacket surrounds the inner vessel and acts as an additional layer of insulation. It is typically made of metal and helps to further reduce heat transfer from the surrounding environment.

Dewar tanks are commonly used in scientific research, industrial applications, and medical facilities for a variety of purposes, such as preserving biological samples, freezing and storing cells, and providing a continuous supply of cryogenic substances for experiments and medical treatments.

Note: The maximum filling capacity is calculated based on the boiling point of the liquid under normal atmospheric pressure. The actual filling capacity is affected by the liquid temperature and pressure inside the container, which is about 95% of the maximum theoretical filling capacity, and about 90% for natural gas.

Production Process

Cnjx High Quality Cryogenic Gas Cylinder Oxygen/Nitrogen Cylinder for Sale

The gas cylinder is easy to use, safe and reliable, economical and durable. The special features are as follows

1.The support system of the inner tank is made of stainless steel to achieve the purpose of low heat loss and high strength.

2. It is easy to use and can be operated independently by a single person.

3. Store pure cryogenic liquid. Large storage capacity. The gas storage capacity of a DP175 Dewar cylinder is equivalent to more than 18 times the gas storage capacity of a standard high-pressure gas cylinder.

4. The internal pressure of the gas cylinder will rise during the deactivation phase after filling. The gas cylinder 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.

5. The built-in supercharger and vaporizer can realize continuous supply of gas or liquid, and there is no need to install an external vaporizer under the designed dosage.

Note: When filling natural gas, use double safety valves and eliminate the rupture disc in the inner tank.

Caution: Adjusting the top screw of the combined pressure regulator does not accelerate the pressurization speed. Adjusting the top pin of the combined pressure regulator at will will result in combined pressure regulation. The valve will be damaged.
