Boiler Controls

One Source Engineering, Inc. is proud to be an Authorized Autoflame Technical Center. The Autoflame Combustion Management System is the state-of-the-art boiler controller.


  • Ensures maximum efficiency of any boiler by optimizing the air-to-fuel ratio.
  • Reduces natural gas consumption through precise servo motor positioning of air dampers and fuel valves. No linkage or cams to wear, jam, or slip!
  • PID Control combined with servo motors and variable speed drive maintains the temperature or pressure set point with extreme accuracy.
  • Reduces electric consumption by using variable speed drives to assure that fan motors and feed water pumps are being operated at optimal speeds.


  • Monitors all boiler parameters continuously for enhanced safety.
  • Achieves ideal combustion accuracy and repeatability.
  • Accommodates remote monitoring and control through your BAS/EMS or via internet.

Autoflame also offers controls for continuous Exhaust Gas Analysis (EGA), and water level controls which offer accuracy and exceptional safety for steam boilers.
