Automatic Switchover Panel for Inert Gases


  • Inert gas delivery
  • Conversion of single cylinder panels to double cylinder panel for improved uptime & reduced costs
  • Improve gas delivery performance & reliability of inert six-pack sources (i.e. Helium)
  • Purge gas source for bulk corrosive systems


  • Purification may be added to eliminate: H2O, O2, and particles
  • Additional outlet for future needs may be incorporated into the same panel
  • Weight based systems are also available for auto-switching of sub-atmospheric gas sources (incorporates cylinder scales, controller, and air operated valves) with remote monitoring capability
  • Standard or customer specific designs can be provided utilizing standard proven components


  • Provides un-interrupted supply of gas by automatically switching source gas from depleted to new cylinder based on pressure set points and Delta P
  • Remote indication is provided to alert the need to replace the empty cylinder
  • Wide flow range meets most common applications
  • Two stage pressure control provides precise delivered pressure to equipment downstream
  • Built-in capability to purge the panel, and/or pigtails during cylinder change from a shared purge source
  • Dimensional drawings are available for standard or custom panels
