Duct Heater

A duct heater is an electrical heating component installed directly inside HVAC systems or air heating units to warm circulating air under non-pressurised conditions. Designed to handle wide temperature fluctuations while maintaining peak efficiency, duct mounted electric heaters consist of an assembly of heating elements mounted on a plate or casing. This heater bundle is inserted inside a duct line or heater body through which air passes and heats to the required temperature.

Whether you need industrial duct heaters for drying, HVAC systems, or process heating, Heater Dekho provides a comprehensive range covering ratings from 0.5 kW to 2000 kW, with support baffle plates, terminal boxes, and control systems tailored to operational requirements. Certified solutions are available for HVAC, manufacturing, and infrastructure applications.

Advantages of Duct Heaters

• Optimized duct heater element arrangement reduces power usage while providing regular temperature output.
• Stainless steel and Alloy 800 sheath materials help prevent air corrosion, moisture, and abrasive particle damage.
• Maximized heat transfer of finned tubular elements reduces energy usage and operating expense.
• Easy removal of components allows rapid installation, spare parts management, and reduced operational downtime.
• Compact size allows easy integration into existing HVAC and duct infrastructure.
• Heavy-duty construction helps eliminate the risk of electric shock.
• Reinforced frame design decreases vibration of the unit during operation.

Applications of Industrial Duct Heaters

• Pre-heating air and heating air for various industrial applications.
• Heating comfort air for commercial buildings, hotels, and large residential complexes.
• Drying chemical pellets and heating processes for manufacturing facilities.
• Multiple zone air heaters for accurate temperature control in HVAC duct heater systems.
• AHU's (Air Handling Units) with integrated heaters, duct assemblies, and combined air handling functions.
• Core drying and pre-drying applications in moisture-sensitive manufacturing such as wood and plastics.
• Using Nichrome wire resistor load banks for high-capacity thermal solutions and electrical equipment testing.
