HVAC Duct Heaters

HVAC Duct Heaters Manufacturer in UAE

National Electric Heaters LLC (NEH) is a UAE-based manufacturer and supplier of HVAC Duct Heaters, providing customized electric air heating solutions for commercial, industrial, and building ventilation systems.

Our electric duct heaters are designed to provide controlled air heating within HVAC ductwork, air handling units (AHUs), and industrial ventilation systems. These heating systems use electric heating elements to raise the temperature of moving air, supporting comfort heating, reheating, and industrial process applications.

NEH offers customized HVAC duct heaters based on heating capacity, airflow rate, duct dimensions, operating voltage, temperature requirements, and installation conditions.

What Are HVAC Duct Heaters?

HVAC Duct Heaters are electric heating devices installed inside or connected to air ducts to heat air passing through a ventilation or air conditioning system.

They typically consist of electric heating elements mounted inside a metal frame or enclosure. As air flows across the heating elements, thermal energy is transferred to the air.

Electric duct heaters are commonly used for air reheating, humidity control applications, temperature maintenance, and supplementary heating in commercial and industrial HVAC systems.

Types of HVAC Duct Heaters

1. Electric Duct Heaters

Electric duct heaters provide controlled heating for air moving through HVAC ductwork. They are suitable for commercial buildings, industrial facilities, and ventilation systems.

2. AHU Electric Heaters

Air Handling Unit (AHU) electric heaters are designed for installation within air handling equipment to provide supplementary heating, reheating, or temperature control.

3. Finned Tubular Duct Heaters

Finned tubular duct heaters use metal fins attached to tubular heating elements to increase the heat transfer surface area for forced-air heating applications.

4. Open Coil Duct Heaters

Open coil duct heaters use exposed resistance heating coils supported by suitable insulating materials. They are commonly used in properly engineered forced-air HVAC systems.

5. Flanged Duct Heaters

Flanged duct heaters are designed for installation between duct sections using suitable mounting flanges, allowing integration into HVAC and industrial air distribution systems.

6. Slip-In Duct Heaters

Slip-in duct heaters are inserted through an opening in the duct wall and secured using a mounting frame or flange, depending on the design.

7. Customized Industrial Duct Heaters

NEH offers customized electric duct heating assemblies according to duct dimensions, heating capacity, electrical specifications, airflow conditions, and application requirements.
