X-Purge: Inert gas or compressed air purge

Install any electrical equipment in a Zone 1 or Class I Div 1 hazardous gas area. X-Purge units:

  • Feed a continuous flow of compressed air or inert gas through the enclosure to purge hazardous gases;
  • Monitor the compressed air or inert gas outflow, not the inflow, to ensure hazardous gases are indeed purged, then,
  • Maintain a positive pressure to stop hazardous gas entering the enclosure or cabinet.

X-Purge units are:

  • Automatic:
    • Timers and control signals  apply and disengage power depending upon conditions reported by the purge system.
  • Complete with:
    • Control unit;
    • Spark arrestor;
    • Relief valve.
  • For all enclosure sizes: Expo designed our X-Purge line for all sizes of enclosure
  • Certified:
    • ATEX,
    • cFMus,
    • cULus,
    • IECEx,
    • INMETRO.

For power isolation devices, please see our complete line of MIU’s (MiniPurge Interface Units) .
