What is PSA Technology and Why is it Preferred?
Today, the demand for industrial and medical gases such as oxygen and nitrogen is rapidly increasing. However, traditional supply methods—liquid oxygen tanks and gas cylinders—bring high costs, logistical challenges, and safety risks. This is exactly where PSA (Pressure Swing Adsorption) technology stands out.
How Does PSA Technology Work?
PSA generators take in atmospheric air via a compressor and purify it from moisture and particles through filters. Special adsorbent materials selectively capture certain gases and release the desired gas.
-
In oxygen generators, zeolite adsorbs nitrogen and produces oxygen at 90–95% purity.
-
In nitrogen generators, carbon molecular sieve adsorbs oxygen and produces nitrogen at 95–99.999% purity.
Since two tanks operate alternately, uninterrupted gas production is ensured. The process requires only atmospheric air and electricity—no additional raw materials.
Why is PSA Technology Preferred?
1. Cost Advantage
-
Eliminates the need for cylinder or liquid gas supply.
-
Operates solely on electricity, offering 50–80% cost savings in the long term.
2. Safety
-
Unlike cylinders, PSA systems carry no high explosion risk. They operate at low pressure (4–8 bar).
-
Certified with international standards such as CE and ISO.
3. Continuity and Reliability
-
Provides 24/7 uninterrupted gas production.
-
Automatically switches to safe mode if purity levels drop.
4. Flexibility and Modular Design
-
Capacity can be increased or decreased as needed.
-
Available in mobile, compact, or field-hospital models for different scenarios.
5. Eco-Friendly
-
Reduces carbon footprint by eliminating the need for transport and storage.
-
Energy-efficient design supports sustainable production.
