GateKeeper Nonreactive Gas Purifiers

Cost-effective, environmentally friendly gas purification
 
GateKeeper Nonreactive Gas Purifiers
  • 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
