Cryogenic storage tanks play a crucial role in various industries, from healthcare to food preservation. This ultimate guide will help you understand what cryogenic storage tanks are, their benefits, and how to maintain them effectively.
What Is a Cryogenic Storage Tank?
A cryogenic storage tank is a specialized container designed to store extremely cold liquids and gases at very low temperatures, typically below -150°C (-238°F). These tanks are essential for preserving and transporting substances that need to be kept at cryogenic temperatures to remain in a liquid state, such as liquid nitrogen, oxygen, argon, and other industrial gases.
Key Features of Cryogenic Storage Tanks
1.Insulation
Cryogenic tanks are highly insulated to minimize heat transfer from the external environment. This insulation is crucial for maintaining the low temperatures required to keep the stored substances in their liquid form.
2.Materials
The materials used to construct cryogenic storage tanks must withstand extreme temperatures. Common materials include stainless steel and other alloys that can maintain structural integrity and prevent corrosion at cryogenic temperatures.
3.Pressure Control
Cryogenic tanks are equipped with pressure relief devices and control systems to manage the pressure build-up caused by the vaporization of the stored liquid. This ensures safety and prevents accidents.
4.Vacuum Jacket
Many cryogenic tanks feature a vacuum jacket, a space between two walls of the tank that is evacuated of air. This vacuum layer significantly reduces heat transfer and enhances insulation.

How Do Cryogenic Storage Tanks Work?
Cryogenic storage tanks are specialized containers designed to hold extremely cold substances, typically liquefied gases such as nitrogen, oxygen, helium, and argon. These tanks operate under principles that ensure the efficient storage and handling of these materials while maintaining their low temperatures. Here’s an in-depth look at how cryogenic storage tanks work:
1. Basic Principles of Cryogenic Storage
Cryogenic storage tanks are built to maintain temperatures below -150°C (-238°F). At these low temperatures, gases turn into liquids, significantly reducing their volume and making them easier to store and transport. The key principle behind cryogenic storage is minimizing heat transfer from the environment to keep the stored liquid at its boiling point or below.

2. Design and Materials
Cryogenic tanks are typically constructed with inner and outer layers. The inner tank, which directly holds the cryogenic liquid, is made from materials with excellent low-temperature properties, such as stainless steel or aluminum. The outer layer, often made from carbon steel, provides structural support and protection.

3. Insulation Systems
To prevent heat transfer, cryogenic tanks employ advanced insulation techniques. The most common method is using a vacuum jacket, where the space between the inner and outer tanks is evacuated to create a vacuum. This vacuum significantly reduces heat conduction and convection. Additionally, multilayer insulation (MLI), composed of reflective foils and spacers, is often added to further minimize radiative heat transfer.

4. Pressure Management
Cryogenic liquids naturally tend to evaporate as they absorb heat from their surroundings, leading to a buildup of pressure inside the tank. Cryogenic storage tanks are equipped with pressure relief valves to safely vent excess gas and maintain pressure within safe limits. Additionally, many tanks have pressure-building systems that vaporize a small amount of liquid to maintain desired pressure levels for consistent dispensing.
