Air contains about 20.947% oxygen, which is essential for life and industrial production. Early oxygen generators were large and inefficient, limiting their use. The advancement of PSA oxygen production technology has made oxygen access more convenient and cost-effective, enabling self-built oxygen systems in 16 major fields.
 

Metallurgy

Blow high-purity oxygen/oxygen-enriched air into steelmaking/non-ferrous metallurgy furnaces to boost output, improve product purity, reduce energy consumption and pollutant emissions.
 

Mining, Beneficiation

On-site PSA oxygen production solves remote mine gas supply issues, enhancing mineral oxidation leaching efficiency and extraction rate while cutting transportation costs.
 

Wastewater and Sewage Treatment

Oxygenation increases dissolved oxygen in water, improving aerobic microorganism activity to efficiently decompose pollutants, suitable for various sewage types with energy-saving advantages.

 

Waste Gas Recovery and Treatment

Assists in decomposing harmful gases (e.g., ozone) into recyclable oxygen, supporting VOCs oxygen-enriched combustion for thorough treatment and resource reuse.

 

Outdoor Work and Sports

 

Provides oxygen support for high-altitude construction, diving, mountaineering, and emergency rescue, preventing hypoxia-related health risks and ensuring work/activity safety.
 

Medical Care and Nursing Care

Critical for hospital treatment (respiratory diseases, ICU patients), elderly care, emergency vehicles, and home medical use, maintaining organ function and improving quality of life.

 

Aviation and Aerospace

Supplies high-purity oxygen for aircraft crew breathing and rocket engines, with mobile PSA systems simplifying refueling and reducing logistics pressure.
 

Chemical Industry

 

Used as raw material/oxidant in producing fertilizers, medicines, plastics, etc., improving reaction efficiency and product yield in processes like synthetic ammonia and coal gasification.
 

Machinery Industry

 

Combines with combustible gases (acetylene, propane) to generate 3000℃+ high-temperature flames for metal welding (firm seams) and cutting (precise cuts), boosting processing efficiency.

 

Aquaculture

Increases water dissolved oxygen via oxygen generators, promoting aquatic organism growth, improving feed conversion rate, and reducing disease incidence in intensive farming.
 

Furnace Combustion Support

Oxygen-enriched combustion (higher oxygen content than air) saves energy, shortens heating time, increases output, reduces pollutants, and extends furnace service life.
 

Metal Welding and Cutting

Oxygen enhances fuel combustion temperature and completeness for high-quality welding (dense seams) and efficient cutting, widely used in machinery manufacturing and steel structure processing.

 

Fermentation Process

 

Stable oxygen supply meets aerobic microorganism needs in food, pharmaceutical, and industrial fermentation, improving efficiency, increasing yield, and reducing contamination risks.
 

Laboratory Research

 

Provides precise oxygen control for medical, biological, environmental, and chemical research, with small/portable generators suitable for low-demand experimental scenarios.

 

Oxygen Enrichment System

Establishes oxygen-enriched environments in plateau dwellings, mines, and sealed cabins, relieving hypoxia symptoms and ensuring personnel health and work efficiency.
 

Waste Combustion

Oxygen-enriched combustion improves waste incineration temperature and efficiency, achieving over 99% organic matter removal, reducing pollutants, and enabling heat recycling.
