VPSA Oxygen Generator with 15-30 Minutes Start-Up Time Stainless Steel Construction for Continuous Operation

The VPSA Oxygen Generator extracts oxygen from air through a periodic cycle of "adsorption-desorption". Its core technology utilizes the adsorption difference of molecular sieves under different pressures—capturing nitrogen at low pressure and releasing impurities under vacuum conditions. Composed of adsorption towers, blowers, PLC control systems and other components, this equipment provides stable oxygen output with 90%-95% purity while consuming only 60%-70% of the energy required by traditional oxygen production methods.

In metallurgical applications, VPSA Oxygen Generators enable oxygen-enriched combustion. In steelmaking plants, blowing 90%-92% purity oxygen into converters increases flame temperature to over 1600°C, accelerating oxidation of impurities while reducing smelting cycles by 20%-30% and coal consumption by 15%-25%. For non-ferrous metal smelting (copper, aluminum), oxygen-enriched processes improve efficiency while reducing harmful emissions like sulfur dioxide.

In chemical production, these generators provide high-purity oxygen for oxidation reactions—such as ethylene oxide production where stable oxygen supply ensures reaction conversion rates exceed 98%. In wastewater treatment, oxygen aeration enhances aerobic microorganism activity, reducing treatment volume by 70% and processing time by 40% compared to air aeration.

Medical facilities utilize VPSA Oxygen Generators for central oxygen supply systems, delivering 93%±3% purity oxygen to patient bedsides and ICU ventilators (5-30L/min flow). This on-site production eliminates risks associated with high-pressure cylinder storage and transportation while ensuring reliable supply for respiratory treatments and critical care.

The system's molecular sieve (0.3-0.5nm pore size) selectively adsorbs nitrogen molecules (0.304nm) while allowing oxygen (0.296nm) to pass through. Operating at 0.1-0.3MPa low pressure and ambient temperature (5-45°C), the dual-tower design alternates adsorption/desorption cycles for continuous production—significantly simpler than cryogenic distillation (-196°C) with lower energy requirements and maintenance costs.
