Nitrogen generators that are based on membrane and pressure swing adsorption (PSA) technologies are both capable of generating nitrogen gas and use compressed air as a means to feed their systems and produce nitrogen. But when deciding which technology will best serve your business, several issues need to be considered.
Pressure Swing Adsorption Generators
A PSA nitrogen generator uses a Carbon Molecular Sieve (CMS) to adsorb oxygen under high pressure while allowing the nitrogen to pass through for collection in a storage unit.
PSA Nitrogen Generator – The Process
With the majority of pressure swing adsorption nitrogen generators, two vessels are packed with carbon molecular sieves (CMS) to adsorb oxygen as compressed air moves through the vessel. As one vessel is adsorbing the second vessel is depressurized, and a small amount of nitrogen flows downward to release the oxygen collected during the adsorption process. The two vessels alternate between the adsorption and desorption processes. The entire process for a PSA generator takes approximately 60 seconds.
PSA Nitrogen Generator Systems
Purity Levels
PSA nitrogen generators can provide higher gas purities than can be accomplished with a membrane nitrogen generator. PSA generators manufactured by On Site Gas Systems offer the ability to achieve a set purity level between 95% and 99.9995%.
Reliability
On Site Gas Systems PSA nitrogen generators have only a few moving parts and if properly maintained can last for many years. It is not uncommon for an On Site Gas Systems PSA nitrogen generators to maintain its performance for over twenty years.
Very Little Maintenance
An On Site Gas Systems PSA nitrogen generator requires very little maintenance. With clean, dry feed air most of the annual maintenance is simply changes filter cartridge. Pellets that form the hub of the pressure swing adsorption gas filtering process (Zeolite or CMS) have an extensive lifespan and can last for at least for decades.
Consistency
Pressure swing adsorption generators can provide the same high volume of nitrogen for the life of the generator
 
 
 

Features and Benefits

• Unlimited flexibility: production capacity can be easily adjusted directly on site by simple module additions without any skilled personnel
• Compact dimensions for installations even in small or low ceiling spaces of your production facility
• Easy fleet management: all OSP models feature the same components, allowing a limited spare parts management and easy maintenance
• Non-corrosive materials such as aluminum and stainless steel, for all process components
