What is a Gas Generator?
A gas generator is equipment that produces gas from air or other feedstocks through processes like pressure swing adsorption (PSA), membrane separation, or electrolysis. On-site gas generation provides reliable, cost-effective alternatives to delivered compressed gas cylinders.
Types of Gas Generators
Nitrogen Generators
PSA nitrogen generators separate nitrogen from compressed air:
-
Pressure swing adsorption technology
-
Purity levels: 95% to 99.999%
-
Output flow: 1 to 5000 Nm³/h
-
Applications: food packaging, electronics, chemical processing
Oxygen Generators
Medical and industrial oxygen generators:
-
PSA or vacuum swing adsorption (VSA)
-
Purity levels: 90% to 95%
-
Continuous or batch operation
-
Applications: medical facilities, wastewater treatment, aquaculture
Hydrogen Generators
Electrolytic hydrogen production:
-
Water electrolysis technology
-
Purity levels: 99.9% to 99.999%
-
Output: 0.1 to 500 Nm³/h
-
Applications: fuel cell testing, metallurgy, chemical synthesis
How PSA Gas Generators Work
Pressure Swing Adsorption Process
1. Compressed air enters the system
2. Air passes through carbon molecular sieve (CMS)
3. Oxygen and water are adsorbed by CMS
4. Nitrogen passes through as product gas
5. CMS regenerates during depressurization
6. Cycle repeats continuously
