Hazardous Location Heaters

Hazardous Location Heaters – Explosion Proof Electric Heaters Built for Safety and Reliability

In high-risk environments—oil & gas facilities, chemical plants, refineries, paint booths, grain elevators, and other classified hazardous locations—standard heaters are not an option. You need equipment certified to contain ignition sources and prevent explosions in Class I and Class II, Division 1 or Division 2 areas.

At NorthStock, we specialize in explosion proof electric heaters and hazardous location heaters designed for these demanding applications. Our lineup includes:

  • Explosion-proof unit heaters – Fan-forced models with high CFM output for large spaces, rapid heat delivery, and precise temperature control.
  • Explosion-proof convector heaters – Natural convection units for quieter operation, lower airflow, and reliable heating in hallways, vestibules, and smaller zones.

All products are UL-listed or CSA-approved for hazardous locations, with rugged construction (heavy-gauge steel, corrosion-resistant finishes, explosion-proof motors and enclosures) that meets NEC requirements and withstands harsh industrial conditions.

FAQ

What is the difference between Division 1 and Division 2?

Division 1 and Division 2 refer to the frequency and likelihood that flammable gases, vapors, or dusts are present in ignitable concentrations in hazardous (Class I or II) locations, per NEC Article 500 (and similar in the Canadian Electrical Code).

These classifications determine the protection level required for electrical equipment (like explosion-proof heaters) to prevent ignition in high-risk environments such as oil/gas facilities, chemical plants, refineries, paint booths, and grain handling.

Quick Comparison

 Division 1Division 2
Hazard Presence During normal operations (continuous/frequent) Only under abnormal conditions (rare/intermittent)
Risk Level Higher (constant or likely exposure) Lower (controlled, contingency-based)
Typical Equipment Rating Explosion-proof, intrinsically safe Non-incendive, purged, or Div 2-rated
Cost & Complexity Higher (more robust containment) Lower (simpler protection methods)
Examples Inside fuel tanks, paint spray booths Adjacent storage rooms, well-ventilated areas

Always consult the latest NEC (NFPA 70), a qualified engineer, or site-specific classification drawings—classifications vary by location. If you're purchasing heaters, share your area classification and we can confirm the right model and send you a quote!

Do you stock replacement parts for explosion proof heaters?

Yes, we stock replacement parts for explosion proof heaters—including thermostats, contactors, and motors. We keep key service components in inventory to help you minimize downtime and avoid long lead times.

For anything we don’t have in stock, we can drop ship directly from the manufacturer (Chromalox, Ruffneck/Thermon, Markel, Berko/QMark, etc.) with fast lead times and full tracking.

Can you provide a quote for my project?

Definitely! Get a fast quote on explosion proof unit heaters, convectors, or custom configurations. Share your specs (kW needed, voltage, mounting, environment, certifications required), and we’ll get to work! Or call us directly at 877-301-4660 – our team is ready to help.
