WATTCO™ duct heaters come in various sizes and dimensions to fit any compartment. Three types of duct heaters are available: open coil, tubular or finned tubular heating elements that are either flanged or inserted in the duct.

Air duct heaters primarily use in air-flowing ventilation systems and comfort-heating applications. Process duct heaters mainly serve industrial process heating applications (ovens that require re-circulated air or forced circulation).

• Wattco duct heater Usage:

Duct heaters are electric heating devices installed within air ducts to provide localized heating in HVAC systems. Its applications include:

1. Commercial Spaces

Duct heaters are mostly used in commercial buildings to maintain indoor temperatures, particularly in large open areas where standard heating is insufficient.

Example: In a shopping mall, duct heaters are installed in the HVAC system to produce warm heat to areas such as food courts or atriums, regardless of outdoor temperatures. It provides a pleasant shopping experience and longer visits.

2. Industrial Applications

Many industries require a temperature control to offer smooth equipment’s operation and maintain safety hazards.

Example: In a manufacturing plant like chemical or plastics, duct heaters are necessary to maintain the air temperature within a specific range and to avoid product damage or defects due to cold elements.

3. Ventilation Systems

During colder climates, the duct heaters are effective in preheating the incoming air in ventilation systems.

Example: In an office building, the duct heater can be fixed in the fresh air intake line to heat the incoming air before it enters the occupied spaces. This improves indoor comfort and energy savings by reducing the load on the main heating system.

4. Zone Heating

Duct heaters enable target heating at specific zones of larger spaces and also help for better energy management.

Example: In a warehouse with different usage levels, a duct heater can be installed in an area where the meetings and gatherings are hosted. It makes that area get heated independently and saves energy when the space is not in use.

5. Dehumidification

Duct heaters can control humidity levels by heating the air to reduce the moisture.

Example: In a swimming pool, a duct heater can be used to heat the indoor pool air. The warm air can reduce moisture and offer a comfortable environment by preventing mold growth and condensation on surfaces.
