A Class I Division 2 (C1D2) heater is an industrial-grade heating device certified for use in hazardous (classified) locations, as defined by the National Electrical Code (NEC).
These heaters are used in environments where flammable gases or vapors may exist under abnormal (not continuous) operating conditions—such as chemical plants, oil refineries, wastewater treatment facilities, or offshore platforms.

Key Class I Div 2 Heater Characteristics:
Explosion proof housing prevents ignition of external gases.
Temperature-limiting devices to avoid overheating.
Corrosion-resistant construction (often aluminum or stainless steel).
Compliant with NEC, CSA, or ATEX/IECEx standards depending on region.
These design elements ensure safety while maintaining thermal performance in challenging industrial settings.
What Affects Explosion Proof Heater Class I Div 2 Price?
Prices for Class I Division 2 heaters vary widely depending on application, material, and electrical characteristics. While many manufacturers offer standard configurations, custom-engineered heaters are often required for specialized environments.

The wattage and voltage configuration of an explosion proof heater determines its heat output, coverage area, and electrical compatibility with your site’s infrastructure.
Typical Wattage Ranges
| Heater Type | Wattage Options | Coverage Area |
|---|---|---|
| Wall Mount | 500W – 10,000W | Small to mid-sized enclosures |
| Duct Heater | 2kW – 25kW | Air handling & ventilation systems |
| Portable Unit | 1.5kW – 5kW | Temporary or localized heating |
Voltage Options
120V / 240V (Single-phase, small enclosures)
480V / 600V (Three-phase, industrial plants)
Custom configurations for international or marine standards
When requesting a quote, always specify your desired wattage, voltage, and ambient operating temperature range. This helps engineers design a heater that fits your application’s safety and performance needs precisely.
Wall Mount vs. Duct Heaters: Which Is Better?
Choosing between a wall-mounted and a duct-mounted explosion proof heater depends on your facility’s airflow requirements and installation constraints.
| Feature | Wall Heater (C1D2) | Duct Heater (C1D2) |
|---|---|---|
| Installation | Mounted directly to wall or column | Installed in HVAC or process duct |
| Best For | Enclosed rooms, control panels, small process areas | Air handling systems, large rooms, process ventilation |
| Airflow Dependency | Optional fan or natural convection | Requires airflow |
| Maintenance | Easy access | More complex |
| Price Range | $1,000–$2,800 | $2,000–$5,500 |
| Temperature Control | Integrated thermostat optional | Often uses remote or external sensor |
Best Choice:
Wall Heaters – Ideal for localized space heating.
Duct Heaters – Best for process air heating or integrated HVAC control.

Do Explosion Proof Heaters Include Thermostats?
Yes — most modern Class I Div 2 heaters can include built-in or remote thermostats for precise temperature regulation.
The choice depends on your application and environment.
Thermostat Options:
Integrated Thermostat:
Compact and convenient.
Ideal for wall-mounted units.
Typically ranges from 40°F–100°F control.
Remote Thermostat or Control Panel:
Used for hazardous or hard-to-reach locations.
Allows fine-tuning from outside the classified area.
Often paired with digital displays or programmable logic controllers (PLC).
For critical process applications, consider using a remote sensing thermostat with feedback loops to prevent temperature overshoot or heater burnout.
Where Are Class I Div 2 Heaters Used?
Explosion proof heaters serve in a wide range of industrial and hazardous-area applications, including:
Oil & Gas: Compressor stations, pump rooms, drilling operations
Chemical Processing: Solvent storage areas, blending rooms
Water Treatment Plants: Gas chlorination facilities
Battery Charging Areas: Hydrogen generation zones
Marine & Offshore Platforms: Engine rooms and bulk storage compartments
Each application demands a heater built to withstand vibration, corrosion, and ignition risks—which is why certification and proper installation are critical.
FAQs About Explosion Proof Heater Class I Div 2 Price
1. Why are Class I Div 2 heaters more expensive than standard heaters?
These heaters undergo stringent testing and certification to ensure safety in explosive environments. The added cost reflects specialized enclosures, flameproof components, and certification fees.
2. Can I use a regular industrial heater in a Class I Div 2 area?
No. Using a non-certified heater in a hazardous location can lead to catastrophic ignition risks and violate OSHA/NEC compliance. Only certified Class I Div 2 units are permitted.
3. How can I reduce installation costs?
Plan early. Choose standard voltage and mounting options whenever possible. Custom voltage or exotic materials drive up costs.
4. Do all Class I Div 2 heaters come with built-in thermostats?
Not necessarily. Some models offer optional thermostats or remote control units. Always verify when requesting a quote.
5. What certifications should I look for when buying an explosion proof heater?
Look for UL 1203, CSA C22.2 No. 30, or ATEX/IECEx labels. These indicate compliance with recognized explosion protection standards.
Industry Benchmarks: Explosion Proof Heater Specifications
| Parameter | Typical Range | Standard/Compliance |
|---|---|---|
| Temperature Class | T3–T6 | NEC/CSA |
| Ambient Range | -40°C to +60°C | Factory tested |
| Watt Density | 5–30 W/in² | Application dependent |
