100Nm³/h 99.5% High-Purity PSA Oxygen Plant for Hospital Oxygen Supply Systems
In hospital diagnosis and treatment systems, oxygen serves as the critical lifeline for sustaining critically ill patients and ensuring surgical safety. The PSA Medical Oxygen Generator (Pressure Swing Adsorption Medical Oxygen Generator) is specifically engineered to meet this essential demand. As the core component of medical oxygen generation plants, it utilizes pressure swing adsorption technology to separate oxygen from nitrogen based on the selective adsorption characteristics of specialized adsorbents for air components.
This system offers significant advantages including rapid oxygen production, stable purity levels, and elimination of frequent consumable replacements. Unlike traditional oxygen supply methods using bottled or liquid oxygen, this PSA oxygen generator eliminates transportation interruption risks and enables 24/7 continuous oxygen production. It is particularly well-suited for high oxygen consumption environments such as tertiary hospitals, providing reliable support for critical departments including emergency rooms, ICUs, and operating rooms.

Why PSA Oxygen Plants are Essential for Modern Hospitals
Post-pandemic, hospitals have experienced significantly increased demand for independent oxygen supply systems. Traditional bottled oxygen presents challenges including transportation delays, limited reserves, and high operational costs. The Pressure Swing Adsorption Oxygen Plant effectively addresses these critical pain points.
With an oxygen output capacity of 100Nm³/h, this system can simultaneously support 30 ventilators, 20 operating rooms, and hundreds of beds for routine oxygen therapy. The 99.5% high-purity oxygen can be directly utilized in critical departments such as neonatology and ICU without requiring secondary purification. Additionally, the equipment features modular design, allowing for gradual expansion as hospital bed capacity increases. Compared to liquid oxygen storage tanks that demand substantial upfront investment, this solution better aligns with hospitals' long-term development strategies.
Core Advantages of PSA Technology in Medical Applications
Medical oxygen generation imposes significantly higher requirements for stability and safety compared to industrial applications. PSA technology for oxygen generation addresses hospital-specific needs through two core design elements: first, the alternating operation mode of dual adsorption towers ensures continuous oxygen production, eliminating the intermittent output issues common with single-tower equipment; second, the medical-grade filtration system effectively removes moisture and impurities from the produced oxygen to below 0.1μm, complying with sterile standards for medical gases.
When compared to Vacuum Swing Adsorption Oxygen Generators, this technology offers lower investment costs and simpler maintenance requirements in small to medium output scenarios (50-200Nm³/h), making it more suitable for the practical needs of most general hospitals.
Working Principle and Maintenance Guidelines
The PSA Oxygen Generator Working Principle operates efficiently: after compression, degreasing, and dehydration, air enters the adsorption tower where lithium molecular sieve preferentially adsorbs impurities including nitrogen and carbon dioxide. The resulting 99.5% purity oxygen is stabilized through buffer tanks before being distributed to hospital pipelines. When an adsorption tower reaches saturation, the system automatically switches to the alternate tower while the saturated unit undergoes pressure relief regeneration, enabling continuous oxygen production.
Three critical maintenance focus areas ensure optimal performance: daily verification of online oxygen purity monitoring data to maintain levels above 99.2%; weekly cleaning of air filters to prevent dust accumulation that could impact adsorption efficiency; and quarterly calibration of pressure sensors and alarm systems to ensure safety devices remain responsive and reliable.
In conclusion, the 100Nm³/h 99.5% high-purity PSA oxygen generator represents not only essential equipment for ensuring hospital oxygen supply security but also a strategic investment for reducing long-term operational costs. Through mature Pressure Swing Adsorption Oxygen Production Technology, it directly converts ambient air into medical-grade oxygen, completely eliminating dependence on external oxygen suppliers and establishing an independent, stable, and cost-effective oxygen supply infrastructure for healthcare facilities.
