Duct heaters are designed to heat air or gases directly within a duct or airflow system. They are widely used in HVAC systems, industrial process heating, and drying applications. Available in open-coil, tubular, and finned-tubular designs, these heaters provide efficient, uniform temperature control with minimal pressure drop.
Constructed with corrosion-resistant materials and customizable mounting options, duct heaters can be integrated into both small and large air handling systems. Optional temperature control systems ensure precise heating for process-critical applications.
