PSA Oxygen Generator

Our oxygen generators use high-quality zeolite molecular sieves as adsorbents to efficiently separate compressed air and consistently produce high-purity oxygen. Compared to traditional oxygen cylinders or liquid oxygen tanks, our generators offer a more cost-effective solution through self-produced oxygen. This continuous gas supply not only eliminates the procurement, operation, and usage challenges associated with high-pressure oxygen cylinders and cryogenic tanks but also provides a stable, permanent source of oxygen. Designed by our technical team, our products feature a compact structure, require minimal space, and can be easily set up by simply connecting to a compressed air source and power supply. All devices can be customized to meet customer needs and support various energy-saving modes, offering flexible solutions for diverse gas requirements.

Benefits
▔▔▔
 
Product Characteristic
▔▔▔
Patented Valve Manifold Design
Our patented modular valve manifold enhances system efficiency, reduces leakage risk, simplifies maintenance, and ensures long-term operational stability.
Precision Digital Flow Meter
Equipped with high-accuracy digital flow meters from SMC (Japan), providing precise flow measurement with real-time data displayed directly on the PLC interface.
Self-Developed Software
KSTouch is our self-developed intelligent control software, designed to deliver a stable, efficient, and user-friendly operating experience across all gas generation systems.
 
 
Application
▔▔▔
Medical Oxygen Supply
Hospitals and clinics typically require 93±3% oxygen purity with stable flow to support patient oxygen therapy, ICU systems, and central oxygen pipelines.
 
Wastewater Treatment
Oxygen is used to enhance aerobic biological reactions. PSA oxygen systems supply continuous enriched oxygen to aeration tanks, significantly improving treatment efficiency and reducing sludge retention time.
Aquaculture Oxygen Enrichment
Fish farming operations rely on controlled dissolved oxygen levels to improve survival rates and growth efficiency.
 
FAQ
▔▔▔
  • What compressed air quality is required for stable operation?
    加 Created with Sketch.
    形状 Created with Sketch.
    Oxygen generator requires clean, dry compressed air. Integrated air filters and dryers ensure stable inlet air quality, protecting molecular sieves and extending system lifespan.
  • How does the operating cost of on-site oxygen generation compare to liquid oxygen or bottled oxygen supply?
    加 Created with Sketch.
    形状 Created with Sketch.
    The operating cost of on-site oxygen generation is significantly lower than that of liquid or bottled oxygen supply due to the reduction of transportation, rental, storage fees.
  • How long is the equipment service life?
    加 Created with Sketch.
    形状 Created with Sketch.
    With proper operation and routine maintenance, the system is designed for a service life of 10–15 years, making it a long-term and reliable oxygen supply solution.
  • How does on-site gas equipment ensure gas purity and stability?
    加 Created with Sketch.
    形状 Created with Sketch.
    Every unit have passed factory tests to make sure they have meet the purity, flowrate, and other requirements. With routine maintenance, the unit will work very steady and reliable for continous oxygen production.
  • What happens if oxygen demand fluctuates frequently?
    加 Created with Sketch.
    形状 Created with Sketch.
    Our specially designed energy saving mode get this problem solved! When demand is low, unit goes into standby mode to save energy, and when demand resumes, the unit will turn on automatically.
  • Can a PSA oxygen generator operate continuously?
    加 Created with Sketch.
    形状 Created with Sketch.
    Yes, it can operate continuously 24/7.
  • How often does the adsorbent in an oxygen generator need to be replaced?
    加 Created with Sketch.
    形状 Created with Sketch.
    With proper maintenance, the molecular sieve typically lasts up to 5 years.
  • What is the typical maintenance cost for an oxygen generator?
    加 Created with Sketch.
    形状 Created with Sketch.
    It depends on the size and configuration of the unit.
