HP Plus Rack Nitrogen Generator


The VICI DBS ® HP Plus Rack 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 micron. For ultra sensitive applications the 19” rack 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 carbon molecular sieve (CMS) which removes O2, CO2 and moisture. These are desorbed to atmosphere during the pressure swing cycle leaving a supply of ultra pure nitrogen.
