Cryogenic vessels (Cryocylinders) are hermetically sealed vessels operating under pressure, designed for cryogenic liquids.
The cryocylinder is a small-volume gasifier shaped as a cylindrical vessel with multilayer screen-vacuum insulation. A spiral-shaped evaporator consisting of a pressure lifting section and a production section is built into the inter-wall space. In upper part of the cryocylinder there are shut-off and safety valves and visual inspection devices (VID). Each cryocylinder can be additionally equipped with a frame with wheels and an atmospheric evaporator of the required capacity.

Cryocylinder composition:
- Internal vessel with piping system made of high quality stainless steel;
- External vessel – “casing”;
- Inter-wall space with high performance screen-vacuum or perlite-vacuum insulation and vacuum maintenance system. The multi-layer insulation system provides long storage life and reduces cryogenic product loss;
- Cryogenic shut-off valves (shut-off valves);
- Vacuum port / valve;
- Safety fittings: vessel and piping safety valves, tank casing protective device;
- Pressure lift evaporator;
- Instrumentation: pressure gauge, differential pressure gauge;
- Pressure regulator with economizer;
- Trunnions and slinging loops;
- “Fill-discharge” unit with connecting fittings (ROTTA nut) and cryogenic filter.
