Cleatech Nitrogen Purge Control system with Oxygen sensor (Oxygen Analyzer) works with inert gas such as Nitrogen and Argon . The system monitors the O2 level 0 to 100% and it’s able to maintain the O2 level inside the enclosure on the desired set point level. It’s an inert gas dual purge system which provides low purge (2-20 Cubic feet per hour) when the O2 level is below the set point maintaining a positive pressure inside the enclosure (e.g glovebox) to have free contaminants and moisture environment. When the oxygen level climbs above an adjustable set point the system automatically activates high-flow purge (20-200 SCFH ).
