Each individual freeze pipe can be operated with a different freezing capacity by specifying a different exhaust gas temperature. Within a central measuring and control unit, temperatures and switching operations can be observed, documented, assessed and changed, thus making the production of tailor-made frost bodies possible. The physical properties of the refrigerant and sophistication of the control system makes ground freezing with liquid nitrogen a highly flexible method with a wide range of applications. The individual plant components such as the supply tank, the pipelines as well as the measuring and control unit can be installed quickly and made ready for operation. Unlike ground freezing using brine, nitrogen as a refrigerant is used up as it escapes in gaseous form back into the atmosphere. Especially in the larger-scale and lengthy ground freezing projects, the volumes of liquid nitrogen used, a consumable item, becomes the most important cost factor.
