Duct Heater

Duct Heaters represent advanced air heating technology specifically engineered for direct installation in air handling units, HVAC systems, and industrial ductwork to efficiently heat non-pressurized air streams. These sophisticated heating assemblies are designed to provide rapid thermal response, uniform airflow heating, and exceptional energy efficiency in demanding air treatment applications. The innovative design enables seamless integration into existing ductwork while delivering precise temperature control and optimal heating performance for diverse industrial and commercial air heating requirements.

Manufactured using premium-grade materials and advanced engineering techniques, these heaters are available in multiple configurations including open-coil designs featuring NiCr resistance elements, straight tubular elements with MgO insulation, and finned-tubular elements for enhanced convective heat transfer. Each configuration is optimized for specific air heating applications, providing superior thermal performance while maintaining low pressure drop characteristics essential for efficient air handling system operation. The robust construction ensures reliable long-term operation under continuous duty cycles.

These versatile heating solutions deliver rapid heat-up capabilities, uniform airflow distribution, and high energy efficiency, making them ideally suited for HVAC systems, cleanrooms, paint booths, industrial drying processes, pharmaceutical air treatment, food processing ventilation, and specialized air handling applications. The advanced design incorporates safety features including over-temperature protection, airflow interlocks, and thermal cutouts to ensure safe operation and prevent element burnout in varying airflow conditions.

Advanced engineering features include precision-manufactured galvanized steel or stainless-steel mounting frames with flanged or slide-in rail configurations for easy installation and maintenance. Weather-resistant terminal enclosures with IP65/67 ratings provide reliable electrical connections and environmental protection. Optional finned configurations mechanically bonded to tubular elements significantly boost convective performance for applications requiring enhanced heat transfer coefficients. High-temperature ceramic fiber insulation and specialized gasketing prevent heat loss and air bypass, ensuring optimal thermal efficiency.

As energy-efficient heating solutions for modern air treatment systems, Duct Heaters offer superior thermal performance through optimized heat transfer design and minimal pressure drop characteristics. The modular construction enables easy maintenance and element replacement while the corrosion-resistant materials ensure extended operational life in demanding environments. Optional hazardous area certifications including ATEX and CIMFR enable safe operation in classified locations, making these heaters essential for industries requiring reliable, efficient, and safe air heating in critical ventilation and process air applications.
