Oxygen Gas

Oxygen (O₂): Essential Gas for Life and Industry

Oxygen (O₂), a colorless, odorless gas constituting 21% of Earth’s atmosphere, is vital for aerobic life and industrial innovation. While non-flammable, it vigorously supports combustion, enabling high-efficiency energy release. Our oxygen is available in gaseous and cryogenic liquid forms (distinctive pale blue when liquefied), meeting ISO 20426 and USP <1075> standards for purity (≥99.5% industrial grade, ≥99.995% medical grade).

Critical Applications

Healthcare

Life support: Administered via ventilators for COPD, COVID-19, and neonatal care.
Hyperbaric therapy: Accelerates wound healing and treats decompression sickness.

Industrial Manufacturing

Steelmaking: Boosts BOF/EAF productivity by oxidizing impurities, reducing carbon emissions.
Oxy-fuel cutting: Achieves 3,500°C flames for precision metal processing (20% faster than air-fuel systems).

Environmental & Emerging Tech

Wastewater treatment: Enhances BOD reduction in aeration tanks.
Rocket propulsion: Liquid oxygen (LOX) powers SpaceX and ESA launch systems.
Ozone generation: Purifies drinking water and industrial effluents.

Safety & Compliance

Oxygen toxicity risk: Requires monitoring above 50 kPa partial pressure.
Cryogenic hazards: Insulated PPE mandatory for liquid O₂ handling.
Certified delivery: Cylinders, bulk liquid, or on-site generators with real-time purity monitoring via GC.
