400-499K BTU LP/NG Indirect Fired Heater

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. This IDF-series heater has a BTU range of 400,000 to 499,000 and features a stainless-steel combustion chamber which keeps combustion air separate from the heated discharge air.
