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

▔▔▔

All surfaces of oxygen-contact components undergo thorough degreasing, and all pipelines are finished with food-grade dual-mirror polishing to ensure they are free from oil, contaminants, and particulates. Reducing ignition risks and ensuring operational safety

Oxygen Safety Treatment
Eliminates cylinder replacement and liquid oxygen deliveries, reducing operating risks associated with high-pressure oxygen handling

On-Site Oxygen Independence
Our system is engineered with an optimized 10:1 air-to-oxygen ratio, delivering 5–15% higher energy efficiency compared to typical solutions on the market

Best-in-Class Air-to-Oxygen Ratio
Based on project experience, on-site oxygen generators typically achieve payback in about two years. With higher energy efficiency, KSTK systems require smaller air compressors for the same output, reducing both CAPEX and OPEX and shortening the ROI to 1–1.5 years

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?

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 long is the equipment service life?

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.
What happens if oxygen demand fluctuates frequently?

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.
