The storage tank consists of an inner vessel of cold-tough material, which is
centrically installed in an external vessel of carbon steel. The gap is
filled with powdered insulation material and evacuated for cooling insulation.
The pressure control can be made by means of a mechanical pressure control
valve or controlled electromechanically, in the case of pure liquid withdrawal,
by the control system CryoServer. Valve bodies are implemented in stainless
steel, all connections are welded.
