PROCESS AIR HEATERS

Installed in forced air ducts, these units supply constant heat for industrial processes requiring air temperatures up to 750°F / 400°C. Construction features include heavy gauge mounting flange, insulated terminal enclosure and easily replaced heating elements. Typical uses include forced air dryers, core drying, heat treating, annealing and other high temperature applications.
