Safe Area vs Hazardous Area Heaters

Understanding when to use standard air heaters versus ATEX/IECEx certified explosion-proof models

Safe Area Heaters

Standard electric duct and space heaters for non-classified locations where explosive atmospheres are not present

Use When:

  • No flammable gases, vapors, or dusts present
  • Standard HVAC and building heating
  • Non-explosive process environments
  • General industrial applications

Product Options:

Electric Duct Heaters Convector Heaters Space Heaters

Hazardous Area Heaters

ATEX/IECEx certified explosion-proof heaters for classified locations with potential explosive atmospheres

Required When:

  • Flammable gases or vapors may be present
  • Explosive dust environments (Zone 20/21/22)
  • Oil & gas, chemical, pharmaceutical facilities
  • Classified Zone 1, Zone 2 locations
