More and more institutions are using cryogenic temperatures in their applications, high interest is seen both in the science world and business. The most common source of cold are cryogenic liquids such as liquid nitrogen and liquid helium. Unfortunately, their use is expensive to operate and requires constant control of the refrigerant. In addition, cooling based on the use of liquid helium or liquid nitrogen is not the safest and requires complex installation. In response to these problems, the Cryogen Free concept was created, using cryocoolers (cryorefrigerators) as a source of cold.
