Hazardous Area Lighting Solutions

Hazardous area lighting for chemical plants, oil refineries, mining operations, and grain silos must prevent ignition of flammable gases, vapors, or dust. Fixtures require Ex certification (ATEX/IECEx) with specific zone ratings (Zone 1/2 for gas, Zone 21/22 for dust), tempered glass rated for thermal shock, and surface temperature limits below auto-ignition thresholds.

Queendom Solution

Queendom provides Hazardous Area Lighting solutions with HL-Ex-Proof series featuring ATEX/IECEx certified explosion-proof housings, tempered glass resistant to thermal shock (5°C to 40°C delta), and surface temperature classification T4 (135°C max) for Zone 1/2 gas and Zone 21/22 dust environments.

Key Advantages:

  • ATEX/IECEx certified: Zone 1/2 (gas) / Zone 21/22 (dust)
  • Temperature class: T4 (135°C max surface temp)
  • Explosion-proof: Flameproof enclosure (Ex d)
  • Tempered glass: Thermal shock resistant
  • Anti-static: Surface resistance < 10^9 ohm
