Cryogenic tanks are essential components in the world of cryotherapy, allowing for the safe and efficient storage and transportation of ultra-low temperature substances such as liquid nitrogen. In this article, we’ll provide an overview of the various types of cryogenic tanks, their uses, and key factors to consider when choosing the right tank for your needs. Let’s dive in!

Types of Cryogenic Tanks

There are several types of cryogenic tanks available, each designed to suit specific applications and requirements. At Cryo Science, we offer a range of high-quality cryogenic tanks to cater to the diverse needs of our clients. The most common types of cryogenic tanks include:

Pressurised Tanks

Pressurised tanks are designed to store cryogenic liquids under pressure, preventing the liquid from evaporating too quickly. These tanks are typically used in applications where a steady supply of high-pressure gas is required, such as in cryotherapy machines and industrial processes.

Vacuum Insulated Tanks

Vacuum insulated tanks feature a double-wall construction with a vacuum layer between the walls. This design minimises heat transfer and helps maintain the ultra-low temperatures required for cryogenic storage. Vacuum insulated tanks are ideal for long-term storage and transportation of cryogenic liquids.

Dewar Flasks

Dewar flasks, also known as vacuum flasks or cryogenic Dewars, are smaller, portable containers designed for the short-term storage and transportation of cryogenic liquids. These flasks typically have a smaller storage capacity compared to pressurised and vacuum insulated tanks but offer greater convenience for smaller-scale applications.

Uses of Cryogenic Tanks

Cryogenic tanks are used in a wide range of applications, including:

  1. Cryotherapy: Cryogenic tanks play a crucial role in cryotherapy machines, providing a steady supply of liquid nitrogen to create the ultra-cold temperatures needed for effective cryotherapy treatments.
  2. Medical and Research Applications: Cryogenic tanks are used to store and transport biological samples, such as blood, tissue, and reproductive cells, for medical research and fertility treatments.
  3. Industrial Processes: Many industrial processes, such as metal hardening, require cryogenic temperatures for optimal results. Cryogenic tanks are used to store and supply the necessary cryogenic liquids for these processes.
  4. Food and Beverage Industry: Cryogenic tanks are used to freeze and transport perishable food items, helping to maintain freshness and quality during transportation.
  5. Space and Rocket Science: Cryogenic tanks are essential components in rocket propulsion systems, storing and supplying cryogenic fuels, such as liquid hydrogen and liquid oxygen.

Key Considerations When Choosing a Cryogenic Tank

When selecting the right cryogenic tank for your needs, there are several factors to consider:


The capacity of the tank is an important consideration, as it determines the amount of cryogenic liquid that can be stored and supplied. Consider your specific needs and choose a tank with the appropriate capacity to ensure a continuous supply of cryogenic liquid.


Cryogenic tanks are typically made from high-quality stainless steel or aluminium, as these materials can withstand the extreme temperatures and pressures associated with cryogenic storage. Ensure that the tank you choose is made from a durable and reliable material.


Proper insulation is crucial for maintaining the ultra-low temperatures required for cryogenic storage. Look for tanks with vacuum insulation or other advanced insulation technologies to minimise heat transfer and improve efficiency.

Safety Features

Safety is paramount when dealing with cryogenic liquids. Ensure that the tank you choose comes with essential safety features, such as pressure relief valves, rupture discs, and oxygen monitors to protect against overpressure, leaks, and other potential hazards.

Compliance with Standards

Make sure the cryogenic tank you choose complies with relevant industry standards and regulations, such as the ASME (American Society of Mechanical Engineers) or the ISO (International Organization for Standardization) guidelines. Compliance with these standards ensures that the tank is designed and manufactured to the highest quality and safety standards.


Depending on your needs, you may require a portable cryogenic tank for easy transportation of cryogenic liquids. In this case, consider a tank with a compact design, sturdy handles, or even wheels for added convenience.

Compatibility with Accessories

To enhance your cryotherapy experience, you may need to use various cryotherapy accessories, such as hoses, thermal clothing, and more. Make sure the cryogenic tank you choose is compatible with the accessories you intend to use.
