GateKeeper® Nonreactive Gas Purifiers
Cost-effective, environmentally friendly gas purification
● Consistently delivers ultrapure gas
● Designed for use with SF6, O2 , N2 O and O2 /inert gas mixtures. The purifiers remove CO2 and H2 O to sub-ppb (part-per-billion) levels; NMHCs to sub-ppt (part-per-trillion) levels.
● Guards against bulk gas purifier breakthrough, impurity spikes from liquid storage tanks, cylinder changeouts and unexpected contaminants in the process
● Does not release hydrocarbons that may contaminate the process
● Uses ambient temperature purification technology – no power or heat required
● Low pressure drop across purifiers
