An Open Ducted Burner Heater is a direct-fired air heating system in which a burner is installed directly within an air duct to heat the process air stream. Combustion takes place in the moving air, allowing rapid heat transfer with minimal thermal losses. The system delivers instant temperature response, high thermal efficiency, and compact installation, making it suitable for continuous industrial drying and heating applications where large air volumes are required.
Used For
Direct heating of process air in industrial dryers
Hot air generation for rotary, belt, and flash dryers
Applications requiring fast temperature ramp-up
Continuous air heating with large airflow rates
Integration into existing ducting and blower systems
