DescriptionThe HP Zero 4000 HC Tower Nitrogen Generator produces nitrogen using a combination of filtration and pressure swing adsorption (PSA) technology. Compressed air is first treated by high-efficiency coalescing filters to remove particulates and liquids down to 5 µm. For ultra-sensitive applications such as GC carrier and make-up gas, an optional heated catalyst module removes hydrocarbons to <0.1 ppm. The air then passes through two columns packed with a proprietary blended carbon molecular sieve (CMS) which adsorbs O2, CO2 and moisture; these are desorbed to atmosphere during the pressure swing cycle, yielding a continuous supply of high-purity nitrogen.
