Gun Style Air Heaters provide the highest mass flows and air temperatures of the 3 styles of Direct Fired Heaters.

1. Gun Style Air Heater Overview
In recent posts we’ve discussed two types of Direct Fired Air Heaters: Packaged Air Heaters and
Duct Air Heaters. The third, and final, type that Stelter & Brinck designs and manufactures is the
Gun Style Air Heater.
This type of air heater is used in applications where the air stream is dirty or low in oxygen. Gun
Style Air Heaters provide the highest mass flows and air temperatures of the 3 styles of Direct
Fired Heaters. As suggested by the name, this type of heater looks like a barrel, built around the
combustion components.
Annealing, metal and glass curing, and ink, chemical, sludge and paint drying are just a few of
the many industries that employee Gun Style units. Stelter & Brinck can design these units to be
fired on gaseous fuels, light, medium or heavy fuel oils or a combination of oil and gas.
