HVAC duct heaters are electric or hydronic heating elements installed directly into air ducts, ventilation systems, or HVAC units to provide supplemental, zoned, or primary heating in commercial, industrial, and residential settings.

Commercial & Industrial HVAC Systems 

• Space Heating:Warms air in offices, warehouses, and factories.
• Make-Up Air (MUA) Units: Heats fresh outdoor air before distribution.
• Ventilation Preheat:Prevents cold drafts in hospitals, labs, and cleanrooms.

Process & Environmental Control

• Humidity Control: Prevents condensation in cold climates.
• Fume & Exhaust Air Heating: Maintains safe temperatures in chemical/industrial exhaust systems.

Specialized Applications

• Data Centers: Prevents cold spots in server rooms.
• Greenhouses:Regulates temperature for plant growth.
• Parking Garages:Reduces ice buildup in ventilation systems.

Advantages

• Energy-Efficient: Heats only when needed (compatible with thermostats).
• Low Maintenance:No moving parts, long lifespan.
• Easy Installation: Fits into existing ductwork.
