What is a cryotherapy machine?

Cryotherapy machine is an equipment used for whole-body cryotherapy. Also called cryosauna (cryo cabin) or cryo chamber. Read about the differences between cryosauna and cryo chamber here.

The principle of work of a cryotherapy machine

Cryotherapy machines work with the use of liquid nitrogen which is plumbed into it from a liquid nitrogen dewar. 

Liquid nitrogen is nitrogen in a liquid state at low temperature (−195.79 °C or −320 °F). It is produced industrially by fractional distillation of liquid air. It is a colourless, low viscosity liquid that is widely used as a coolant. Its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications, primarily as an open-cycle refrigerant.

78% of the air we breathe consists of nitrogen, which isn’t dangerous itself. But good ventilation is required for cryotherapy centres conducting a lot of procedures per day. In the small and bad ventilated room the oxygen content can fall below 20% (by volume) and sooner or later it can cause tangible discomfort or even loss of consciousness. 

During the cryo session, individuals are required to wear basic protective clothing to prevent cold-related injuries: dry socks and slippers, shorts for males and a combination of shorts and a top for females. The influence of extremely cold temperatures produced by cryotherapy machines is still being researched, but most results reveal a more pronounced stimulation effect of whole body cryotherapy than that of its localized version.

What kind of cryotherapy machines (cryosaunas) are?

There are two options for nitrogen feed for cryotherapy machines: from non-pressurized Dewar tanks or from bigger pressurized containers. Non-pressurized Dewar tanks are smaller and easier to handle, pressurized tanks are heavier and bigger, but money-saving. You can read about all features of these two types of nitrogen feed here.

The majority of today’s cryotherapy machines are made with comfort in mind, which includes soft cushioning in the interior, advanced security features, wireless controls, touch-sensitive information displays, and even a built-in audio system. 

The price of cryotherapy machines depends on the additional features and its options.
