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) .

• SmartPurge II (SP2-PX-ss)
