Nitrogen Generator

The HP Zero N2 Tower Nitrogen Generator produces nitrogen by utilizing a combination of filtration and pressure swing adsorption (PSA) technology. Standard compressed air is filtered by high-efficiency coalescing filters to remove all contaminants down to 5 µm. For ultra-sensitive applications such as GC carrier and make-up gas, units also include the additional heated catalyst module to ensure hydrocarbons are removed to <0.1 ppm. The air then passes through two columns filled with a proprietary blended carbon molecular sieve (CMS) which adsorbs O2, CO2, and moisture. These are desorbed to the atmosphere during the pressure swing cycle leaving a supply of ultra-pure nitrogen.
