Duct Air Heater Overview

Duct Air Heaters are one type of direct fired air heater used in industrial applications. These industrial heaters provide the hot air used to manufacture everything from clay and brick to coal and glass. Duct Air Heaters earned their name due to the fact that they are designed to be inserted right into the process ductwork. These heaters most often fire on natural gas, propane and butane.
