Cryogenic tanks

SIG TRADING FZCO supplies high-quality cryogenic tanks of its own production, with over 50 years of experience in this field and a guarantee of high product quality. Stationary tanks are the simplest, most cost-effective, and convenient way to store liquefied gases, allowing you to minimize transportation, installation, and maintenance costs. Our plant specializes in the design and manufacture of such equipment. We offer cryogenic tanks of suitable models at manufacturer prices. As additional services, we provide warranty and after-sales service for the supplied equipment, as well as diagnostics during its operation and subsequent service life extension.

A cryogenic tank is a double-walled vessel designed for storing cryogenic products and consists of:

  • Inner vessel made of high-strength stainless steel

  • Outer tank

  • Inter-wall space filled with vacuum-powder insulation (perlite)

  • Evaporator designed to maintain the required pressure level inside the cryogenic tank

  • Shut-off and safety valves (valves, cocks, membranes)

  • Control and measuring instruments (sensors, pressure gauges)

Advantages of cryogenic tanks developed and manufactured by our company:

  • Low evaporation losses

  • Safety during long-term storage

  • Chemical and mechanical resistance of the materials used

  • Fast filling and emptying of tanks

  • Low losses of cryogenic products during initial filling


Cryogenic Gasifier (CG) is used for storing liquid oxygen, nitrogen, argon, and carbon dioxide (O₂, N₂, Ar, CO₂), their cold gasification, and supplying gaseous products into the network. Depending on the customer’s requirements, it is possible to ensure any required consumption of evaporated gas.

The gasifier is equipped with fittings, an atmospheric evaporator for liquid gas gasification, control devices, safety devices, and pipelines. Evaporation of liquid gases takes place in atmospheric evaporators using the heat of the surrounding air, so no other heat sources (steam, hot water, electric heating) are required.

The gasifier consists of a cryogenic tank made from an inner vessel and a casing with effective vacuum insulation. The required temperature and pressure for storing liquid cryogenic gases are maintained automatically, without the need for constant supervision during operation.

Cryogenic gasifiers can be used to obtain gaseous oxygen and further supply it to medical institutions, laboratories, and as gas-filling stations for cylinder filling. Depending on the consumption, it is possible to manufacture a cryogenic tank within a gasifier up to 100 m³ in volume.
