Industrial & Liquid Nitrogen Gas (N₂)
Nitrogen gas (N₂) is one of the most widely used industrial and laboratory gases worldwide. It is a colorless, odorless, and inert gas, commonly used as an inerting and blanketing medium in various industries such as food processing, petrochemicals, pharmaceuticals, electronics, and refrigeration. ParsiaGas supplies nitrogen in liquid form (LN₂), cylinder/bundle packages, and bulk storage systems, fully compliant with international standards.

What is Nitrogen Gas?
Nitrogen (N₂) is an inert, non-reactive gas that makes up about 78% of the Earth’s atmosphere.
It is colorless and odorless, widely used across industries to prevent oxidation, create inert atmospheres, provide cooling, and support cryogenic processes.
Applications of Nitrogen
- Food industry: MAP packaging (Modified Atmosphere Packaging) and rapid freezing (IQF)
- Medical & laboratory: Cryotherapy and cell preservation at −196°C
- Petrochemical and oil & gas: Inerting pipelines and storage tanks
- Electronics: Preventing oxidation during semiconductor manufacturing

Safety & Downloads
Nitrogen gas is inert and non-toxic, but in confined spaces it can displace oxygen and cause asphyxiation.
When handling liquid nitrogen, always use proper cryogenic gloves and safety goggles.
Avoid rapid discharge of nitrogen in small or poorly ventilated areas.

FAQ
What are the applications of nitrogen?
Nitrogen is used in the food industry for modified-atmosphere packaging, in petrochemicals for inerting, in the medical field for cryotherapy, and in laboratories for drying and purging processes.
Is nitrogen dangerous?
Nitrogen is safe at normal pressure, but in confined spaces it may replace oxygen and cause suffocation.
What is the difference between liquid nitrogen and gaseous nitrogen?
Liquid nitrogen (LN₂) is stored at −196°C and used for freezing, cooling, and cryogenic applications, while gaseous nitrogen is used for pressurizing, inerting, and industrial processes.
Is nitrogen edible?
Pure nitrogen is safe for indirect contact with food (such as MAP packaging or freezing), but it is not consumed directly.
What nitrogen grades are available?
Industrial grade, food grade, pharmaceutical grade (Pharma Grade), and high-purity laboratory grade.
What is the standard cylinder color for nitrogen?
According to EN1089-3, nitrogen cylinders have a black body and a black shoulder.
Does Parsiagas provide on-site refilling services?
Yes, for contract customers, bulk-tank refilling or cylinder supply is available.
