At this year’s CONEXPO, SunFire is proud to showcase the next evolution in commercial heating performance, the new Diesel Indirect Heater. Attendees can see it up close and meet the SunFire team at booth C30034, where innovation, reliability, and American-made quality are on full display.

Built on the same trusted platform as the rest of the SunFire heater lineup, the SFiD500 delivers the durability and performance customers have come to expect from SunFire. This new diesel-powered indirect heater is designed specifically for demanding commercial and industrial environments. From construction sites and temporary structures to event spaces and maintenance operations, the SFiD500 is engineered to provide clean, consistent heat where it is needed most.

At the core of the SFiD500 is a high-efficiency heat exchanger design that delivers safe, indirect heat while maximizing fuel efficiency. With continuous operation at 500,000 BTU per hour, the unit is built for extended runtimes in tough conditions. The indirect heating configuration ensures combustion byproducts remain separate from the heated air, making it suitable for enclosed or occupied spaces where air quality is critical.

The SFiD500 runs on diesel fuel or kerosene, offering dependable performance and easy fuel availability on jobsites. Electrical requirements remain simple and jobsite friendly. The unit operates on 120 volts with a maximum draw of 15 amps, allowing it to integrate easily into existing power sources without specialized electrical setups. This combination of diesel heat and low electrical demand helps minimize downtime and maximize flexibility.

Ease of use is a key focus of the SFiD500 design. The heater is easy to maintain, with service-friendly access that reduces maintenance time and keeps crews productive. Its portable, rugged construction allows it to withstand harsh environments while remaining easy to transport and reposition as site conditions change.

Proudly made in America, the SFiD500 reflects SunFire’s commitment to quality craftsmanship, reliable components, and domestic manufacturing. Every detail, from materials to assembly, is designed with long-term performance in mind.
