Nitrogen Generators

We partner with Generon to deliver nitrogen generator systems using pressure swing adsorption (PSA) technology to our customers in New England. PSA nitrogen generators are typically used in application where high purity gas (more than 99.5% nitrogen) is a requirement. In the modern manufacturing environment, such as bio-medical technology and food processing, the requirement for high purity nitrogen and other analytical gases continue to grow.

How does PSA technology work?

Generon Twin Tower PSA nitrogen generator system

PSA technology processes separate gases in air like nitrogen from oxygen and other trace gases. When under pressure, gases are attracted to solid surfaces in a process known as adsorption. If a gas mixture passes through a pressurized vessel filled with an adsorbent bed of zeolite carbon that nitrogen more strongly than it does oxygen, most or all the the nitrogen will stay in the bed. The gas coming out of the vessel be oxygen-rich. When the zeolite bed reaches its maximum absorption capacity, nitrogen can be regenerated by reducing the pressure in the vessel. The adsorbed nitrogen is released when the pressure drops to produced high-purity nitrogen. The cycle then repeats.
