Direct Fired Process Air Heater Types: Duct Style, Gun Style and Packaged

Used in processes that require a hot air source, Direct Fired Air Heaters are ideal for applications that are not sensitive to the by-products of combustion. As their name implies, Direct Fired Process Air Heaters apply heat directly to the product air stream.
