In the hospital diagnosis and treatment system, oxygen is the
"lifeline" for sustaining the lives of critically ill patients and
ensuring surgical safety. The psa medical oxygen generator
(Pressure Swing Adsorption Medical Oxygen Generator) is a key
equipment developed to meet this core demand. As a core component
of the medical oxygen generation plant, it realizes oxygen-nitrogen
separation based on the principle of pressure swing adsorption,
utilizing the selective adsorption characteristics of special
adsorbents for air components. It boasts advantages such as fast
oxygen production speed, stable purity, and no need for frequent
consumable replacement. Compared with traditional oxygen supply
methods using bottled oxygen or liquid oxygen, this psa oxygen
generator can avoid the risk of transportation interruption and
realize 24/7 continuous oxygen production. It is particularly
suitable for high oxygen consumption scenarios such as tertiary
hospitals, providing reliable support for key departments including
emergency rooms, ICUs, and operating rooms.

Why is the psa oxygen plant for hospital Indispensable for Modern
Hospitals?
After the pandemic, hospitals' demand for "independent" oxygen
supply has significantly increased. Traditional bottled oxygen has
problems such as transportation delays, limited reserves, and high
costs, while the pressure swing adsorption oxygen plant (Pressure
Swing Adsorption Oxygen Plant) can fundamentally solve these pain
points. An oxygen output of 100Nm³/h can simultaneously meet the
needs of 30 ventilators, 20 operating rooms, and hundreds of beds
for routine oxygen therapy. The 99.5% high-purity oxygen can be
directly used in key departments such as neonatology and ICU
without secondary purification. In addition, the equipment adopts a
modular design, which can be gradually expanded as the number of
hospital beds increases. Compared with liquid oxygen storage tanks
that require huge one-time investment, it is more in line with the
long-term development plan of hospitals.
Core Advantages of psa technology for oxygen generation in Medical
Scenarios
Medical oxygen generation has much higher requirements for
"stability" and "safety" than industrial scenarios. The psa
technology for oxygen generationadapts to hospital needs through
two core designs: first, the alternating operation mode of double
adsorption towers ensures continuous oxygen production, avoiding
the intermittent oxygen production problem of single-tower
equipment; second, the medical-grade filtration system can filter
moisture and impurities in the produced oxygen to below 0.1μm,
complying with the sterile standard for medical gases. Compared
with the Vacuum Swing Adsorption Oxygen Generator, this technology
has lower investment costs and simpler maintenance in small and
medium output scenarios (50-200Nm³/h), making it more suitable for
the actual needs of most general hospitals.
Working Principle and Daily Maintenance Focus of Medical psa oxygen
plant working
ThePSA Oxygen Generator Working Principle is not complicated: after
being compressed, degreased and dehydrated, the air enters the
adsorption tower; the lithium molecular sieve preferentially
adsorbs impurities such as nitrogen and carbon dioxide, and the
oxygen with 99.5% purity is sent to the hospital pipeline after
pressure stabilization by the buffer tank; when the adsorption
tower is saturated, the system automatically switches to the other
tower for operation, while the saturated tower is regenerated by
pressure relief to realize continuous oxygen production. Three key
points should be focused on in daily maintenance: check the online
oxygen purity monitoring data daily to ensure the purity is not
lower than 99.2%; clean the air filter weekly to avoid dust
blockage affecting adsorption efficiency; calibrate the pressure
sensor and alarm system quarterly to ensure the safety devices are
sensitive and reliable.
In conclusion, the 100Nm³/h 99.5% high-purity psa oxygen generator
is not only a core equipment for hospitals to ensure oxygen supply
safety, but also a wise choice to reduce long-term operating costs.
Through the mature Pressure Swing Adsorption Oxygen Production
Technology, it directly converts air into medical oxygen,
completely getting rid of the dependence on external oxygen supply
and building an independent, stable and economical oxygen supply
system for hospitals.
