Gaseous and liquid Nitrogen N2
Nitrogen is produced by low temperature separation of the atmospheric air.
Application
Gaseous nitrogen is used for producing inert atmosphere in production, storage and transportation of highly oxidizable products, in high temperature treatment of metals not reacting with nitrogen, for conservation of closed metal vessels and pipelines. Liquid nitrogen is used as a coolant.

Packing, transportation, storage
Nitrogen is transported in buyers’ containers: gaseous nitrogen in 6,2 m3 cylinders, liquid in cryogenic vessels.
The product may be transported by railway and road trucks in accordance with the rules of goods carriage applicable for the relevant mode of transport.
Cylinders filled with nitrogen are stored in special storage rooms or out of doors under the shed protecting them against atmospheric precipitation and direct sun light.
Guaranteed storage life
Gaseous nitrogen: 18 months from the date of manufacture.
