Nitrogen (N₂, R-728)

Nitrogen (N₂, R-728) is a colorless, odorless, and inert gas that is non-flammable and non-toxic. It is produced in large volumes by fractional distillation of liquefied air at air separation units. Nitrogen is available in various purity grades, with high-purity nitrogen undergoing additional purification processes. It is supplied in high-pressure cylinders or as a cryogenic liquid.

Recommended regulator: W019130 or W019230 for cylinder use.

APPLICATIONS:

Nitrogen is highly versatile and used across numerous industries:

• In the chemical and petrochemical industries for blanketing, purging, and pressure transfer of flammable substances.
• In food and beverage packaging (Modified Atmosphere Packaging – MAP) to extend shelf life.
• In electronics and semiconductor manufacturing for inert atmospheres.
• In metal processing for heat treatment and cooling.
• In laboratories, medical storage, and biological sample preservation (when supplied as liquid nitrogen).

FEATURES & BENEFITS:

• Inert and non-reactive, ideal for processes that require contamination-free environments.
• Available in multiple purity levels to suit industrial, scientific, and food-grade applications.
• Can be supplied in compressed gas or liquid form depending on application needs.

HAZARDS:

• Asphyxiant at high concentrations – displaces oxygen in confined spaces.
• Cold burns or frostbite risk when handling liquid nitrogen – use protective gear.
• Ensure proper ventilation and safety protocols when using in enclosed areas.
