  • Applications
  • Low-NOx Emissions as low as 30 ppm achieved without FGR
  • 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 using less horsepower and less noise
  • Lower maintenance cost with no FGR or air filters needed
  • 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-30 series is designed for a variety of boiler types such as firetubes, and watertubes. Capable of less than 30 ppm NOx emissions without FGR, the SBR-30 series features a unique firing head design to achieve controlled combustion leading to low emissions with 3% O2. Advanced technology allows the SBR-30 series to offer low-NOx, low CO emissions and up to 10:1 turndown on natural gas.
