Nitrogen Generators

As a distributor for the Filtration and Separation Division of Parker Hannifin Corporation, Valin offers domnick hunter nitrogen generators systems for modified atmosphere packaging applications to reduce oxygen content inside a package and extend food product shelf systems.

A domnick hunter Nitrogen Generator will deliver 5% down to 10 ppm oxygen content without the need for additional purification from nearly any compressed air supply. The generators are designed to continually transform standard compressed air into nitrogen at safe, regulated pressures without operator attention. Generating nitrogen in-house eliminates the challenges associated with outside vendors and ensures long-term cost stability.

Nitrogen is produced through a combination of filtration and pressure swing adsorption technology (PSA). High efficiency pre-filtration removes contaminants from the compressed air. The air entering the generator is comprised of 21% oxygen and 78% nitrogen. The gas separation process preferentially adsorbs oxygen over nitrogen using carbon molecular sieve (CMS). At high pressures, the CMS has a greater affinity for oxygen, carbon dioxide, and water than it does at low pressures. By raising and lowering the pressure within the CMS bed, all contaminants are captured and released, leaving the CMS unchanged. This process allows the nitrogen to pass through as a product gas at pressure.
