The oxygen with 99.5% purity generated by the 99.5% oxygen generator balances cost and purity, and is widely used in medical treatment, metallurgy, cutting, chemical industry, water treatment, glass manufacturing, laboratories, special manufacturing and other fields.

  I. Metal Processing and Metallurgy (Largest Oxygen Consumption Scenario)

  Flame Cutting & Welding

CNC flame cutting of carbon steel, stainless steel and thick steel plates, as well as air gouging of thick workpieces. Oxygen at 99.5% purity delivers stable combustion, smooth cutting surfaces and no slag adhesion. Compared with 93% purity oxygen, it features faster cutting speed and lower consumable loss, making it the mainstream choice for shipyards, steel structure factories and construction machinery manufacturers.

  Oxygen Blowing for Steelmaking Converters

Decarbonization and temperature rise in electric furnaces and converters to improve molten steel purity and reduce impurities; deoxidation and steel grade adjustment in refining furnaces.

   Non-Ferrous Metal Smelting

Oxygen-enriched smelting for copper, lead, zinc and nickel production to raise furnace temperature, boost ore recovery rate and cut coal consumption; oxidation processes for precious metal purification.

  Aluminum Processing

Oxygen supply for impurity removal during refining of aluminum foil and aluminum sheets, as well as oxidation coloring processes.

  II. Chemical Industry

   Oxidation Synthesis Reactions

Used as an oxidant in catalytic reactions for the production of ethylene oxide, ethylene glycol, acrylic acid, formaldehyde, hydrogen peroxide and titanium dioxide. Its low impurity content prevents catalyst poisoning.

   Oxidation Treatment of Wastewater and Exhaust Gas

Raw material for ozone generation (ozone is produced via corona discharge of oxygen). Applied to decolorization of chemical wastewater, COD degradation and heavy metal removal; serves as combustion-supporting gas to oxidize and decompose VOCs in incineration exhaust.

   Petrochemical Industry

Catalytic cracking of heavy oil, biochemical aeration of wastewater, and oxygen-enriched oil displacement in underground wells.

  III. Glass and Building Materials Manufacturing

   Oxygen-Enriched Combustion in Float Glass & Photovoltaic Glass Furnaces

Replacing air with 99.5% oxygen for combustion raises furnace temperature and reduces heat loss caused by nitrogen absorption, achieving 20%–40% energy savings. It produces glass with uniform light transmittance and drastically fewer bubble defects.

   Melting of Quartz Glass and Special Glass

High-purity oxygen supply prevents glass discoloration and the formation of impurity bubbles.

   Firing of Refractory Materials

  IV. Water Treatment and Environmental Protection

   Gas Source for Ozone Systems

Ozone disinfection in waterworks, purified water plants, swimming pools and sewage treatment plants. 99.5% oxygen generates high-concentration ozone for sterilization, algae removal, residual chlorine elimination and organic matter degradation.

   Advanced Oxidation Processes (AOP)

Advanced treatment of printing and dyeing wastewater, electroplating wastewater and landfill leachate to oxidize and decompose refractory pollutants.

   High-Density Aquaculture

Oxygenation for industrial recirculating aquaculture and long-distance live fish transportation. Free of harmful impurities, high-purity oxygen increases dissolved oxygen in water and reduces disease outbreaks.

  V. Laboratories, Testing and Light Industry

   Combustion Analysis Instruments

Carbon-sulfur analyzers, elemental analyzers and thermogravimetric analyzers for composition testing of metals, ores and coal.

   Glass Blowing & Jewelry Welding

Micro-welding of gold and silver jewelry and precision hardware, delivering soft flames without oxidative discoloration.

   Fermentation Industry

Oxygen-enriched aeration for fermentation of antibiotics, amino acids and yeast, which accelerates strain metabolism and shortens fermentation cycles.

  VI. Energy and Special Industries

   Fuel Cell Testing

Performance testing of proton exchange membrane fuel cells; medium-purity oxygen meets standard durability test requirements.

   Combustion Support for Garbage and Hazardous Waste Incineration

Oxygen-enriched combustion fully decomposes dioxins and reduces flue gas emissions.

  Emergency Oxygen Supply for Ships and Tunnels

Temporary oxygen supply in confined spaces (not for medical emergency rescue, solely to maintain ambient oxygen concentration).
