● The absorber adopts special airflow distribution structure to ensure uniform distribution of airflow and improve the utilization rate of the molecular sieve bed layer.
● Adsorber's structure of vertical double bed, the lower active aluminum oxide can reduce the influence of water on the molecular sieve adsorption performance, and at the same time of molecular sieve regeneration can improve molecular sieve's service life through nitrogen desorption and clean air for aluminum oxide no heat regeneration.
● After a long time of practice, we use imported professional molecular sieve to generate oxygen. Its performance is stable and reliable. Using special active aluminum oxide for PSA, it can effectively protect the molecular sieve.
Where Are VPSA oxygen generators applied? Typical applications
VPSA systems are excellent for high flow rate oxygen supply (usually 100-5,000 Nm³/h) at medium purity. That’s the difference they’re making now: Waste Water Treatment Plants: Oxygen injection speeds up bacterial decomposition of organics, enhancing treatment efficacy. Metal Fabrication: Improved combustion during metal cutting and welding means more productivity. Glass Manufacturing: Oxygen-enriched furnaces yield better quality glass with lower emissions. Pulp & Paper: Oxygen delignification decreases chemical consumption and environmental burden. Aquaculture: The Optimal Amount of Oxygen in Fish Farms for Healthier Stock and Greater Density. Chemical Manufacture: A number of oxidation processes in the production of chemicals require dependable oxygen supplies.
VPSA and PSA Nitrogen Generators: What are the Differences?
How is a VPSA oxygen generator vs a psa nitrogen system People also ask Both technologies apply similar principles of adsorption technology, but have key differences:
Aspect
VPSA Oxygen Generators
PSA Nitrogen Generators
Primary Product
Oxygen (90-95% purity)
Nitrogen (95-99.999% purity)
What's Captured
Nitrogen is adsorbed, oxygen passes through
Oxygen is adsorbed, nitrogen passes through
Sieve Material
Nitrogen-selective zeolite
Carbon molecular sieve (CMS) or oxygen-selective zeolite
Pressure Range
Lower pressure (0.3-0.6 bar) with vacuum assist
Higher pressure (4-8 bar typically)
Energy Efficiency
Excellent for large-volume oxygen production
Excellent for high-purity nitrogen requirements
Scale Advantage
More economical for oxygen volumes above 100 Nm³/h
More economical for nitrogen across wide capacity ranges
Key Strength
Lower operating costs for high-volume oxygen needs
Ability to achieve very high nitrogen purity levels
Why Choose VPSA?
After two decades in this industry, here's what we've observed about why businesses choose VPSA oxygen generators:
Energy Efficiency: the vacuum-assisted regeneration greatly reduces the power consumption when compared with conventional PSA oxygen generation systems. Reduced Energy Costs: Lower energy consumption means lower operational costs. Large Capacities: VPSA is especially efficient in applications requiring large amounts of oxygen. Reliability: Modern VPSA systems have exceptional uptime due to less moving parts than conventional compressors and intelligent switching between vessels. -Dan Polyakov, NTEP LLC. Customizable: Our systems are engineered to meet your specific capacity requirements with modular design options for expansion. Fast Payback: If you are using liquid or cylinder oxygen now, switching to on-site VPSA generation typically pays for itself in 1-3 years.
