How do cryogenic tanks stay cold?

Cryogenic storage tanks are designed through a range of technologies and designs to maintain a cryogenic environment inside them. Here are the main ways to keep your temperature cold:

Insulation material

The storage tank adopts a double-layer structure, the inside is a storage tank, and the outside is an insulating layer and a protective layer. Insulating materials such as polyurethane foam are used on the tank walls and bottoms to effectively reduce heat transfer from the outside environment into the inside of the tank. At the same time, the exterior of the storage tank may also use insulation layers such as steel plates, aluminum foil, and vacuuming to further enhance the insulation effect.

Vacuum insulation

In the enclosed space of the walls and insulation of the storage tank, high-pressure insulation material is injected to form vacuum insulation. This vacuum minimizes heat transfer and convection, keeping the tank cold.

High-pressure insulation

High-pressure insulation plays a key role in storage tanks, they can effectively prevent the transfer of heat and keep the liquid in the storage tank cold. Even if the liquid evaporates or heats up at a very small rate in the tank, the high-pressure insulation ensures that its temperature remains within the desired range.

Intelligent controllers

Some storage tanks use intelligent controllers, such as the chip Feihu embedded intelligent controller, which can monitor the temperature and pressure of the storage tank in real time. This real-time monitoring ensures that the liquid in the tank is always at a safe and stable low temperature.

Regular maintenance

Maintenance and upkeep of cryogenic storage tanks is also key to ensuring that they can remain cold. Regularly check whether the insulation layer, support structure, inlet and outlet port, pressure relief port, temperature measuring hole, etc. of the tank wall are in good condition, and clean the inner and outer surfaces of the tank wall to ensure the reliability and safety of the tank body, so as to maintain its good thermal insulation performance.
To sum up, cryogenic storage tanks can effectively maintain the low temperature environment inside them by combining a variety of insulation technologies, materials and intelligent control systems to meet the needs of various application scenarios.
