The Tempstar T9MPX, also known as Smart Comfort DLX95, is a single-stage furnace that can be installed in upflow, horizontal or downflow applications. It has an AFUE rating of 95 percent.
The T9MPX uses an RPJ III primary heat exchanger made from corrosion-resistant stainless steel. It is designed with rippled edges that the manufacturer says push extra heat to the outside surface for increased efficiency. When installed using the direct vent option, clean outdoor air is used for combustion, ensuring the heat exchanger is exposed to few corrosive chemicals. Fuel efficiency is maximized through the incorporation of the multi-speed PCS circulation blower with timed delays, induced draft blower and gas valve.
The direct hot surface ignition system uses a silicon nitride ignitor, while advanced electronic controls monitor the system. Finally, noise during operation is minimized by the thermal-lined, insulated cabinet.
