Indirect-Fired IDF-400HS

Indirect-fired heaters are typically installed outside a structure with ductwork drawing the heated air inside the facility. This heater type works similarly to a home furnace by forcing outside air through a heat exchanger and into the space while diverting products of combustion outside of the space through a chimney. IDF-series heaters feature a stainless steel combustion chamber which keeps combustion air separate from the heated discharge air. The IDF-series of indirect-fired heaters are recommended for cleanroom projects for pharmaceutical manufacturing, medical device manufacturing, and other industrial applications where maintaining a controlled environment is crucial.
