CryoTank Specifications
Storage tank for liquid nitrogen

Application
CryoTank is a stationary storage tank for the safe storage and withdrawal of deep- cold, liquified nitrogen. The employment of a storage tank type VT 2 is recommended starting from a monthly liquid nitrogen consumption of 1.000 litres. Starting from a monthly consumption of 10.000 litres the storage tank type VT 11 is recommended.

Structure

Description
The storage tank consists of an inner pressure tank of cold-resistant material, which is centrically installed in an outer container of carbon steel. The gap is filled with powdered insulation material (perlite) and evacuated for cooling insulation. The pressure control can be handled though a mechanical pressure control valve or, in case of pure liquid withdrawal, can be controlled electromechanically, by the control system CryoServer. Valve bodies are made of stainless steel, all connections are welded.
