The ProFire® SBR-5 series burner, capable of less than 5 ppm NOx emissions with FGR, offers: natural gas fuel option from 10.5 to 42 MMBTU/hr.
- Ultra-Low-NOx Emissions as low as 5 ppm achieved with FGR
- 3~4% O2 across a wide load range
- Maximum Efficiency provided by standardized parallel positioning
- Uniform Flame for equal heat transfer allowed by premix fuel
- Easy Access air housing for internal components
- Silent operation with an advanced combustion air fan wheel; Less horsepower and less noise
- Induced FGR modulating valve
- Ultra-Low-NOx/CO achieved without a fragile surface combustion burner head, making it safer and more reliable, and requires less maintenance
- Integrated Controls with remote IoT monitoring capabilities
The ProFire SBR-5 series is designed for a variety of boiler types such as firetubes, and watertubes. Capable of less than 5 ppm NOx emissions with FGR, the ProFire SBR-5 series features a unique firing head design to achieve controlled combustion leading to ultra-low emissions with 3% O2. Advanced technology allows the SBR series to offer ultra-low-NOx, low CO emissions and up to 8:1 turndown on natural gas.
