FLX Premix

Low Emissions Performance

  • Steam and hot water
  • 75 to 250 HP
  • Available to <9 ppm NOx, ultra-low CO 
  • Natural gas or propane fuel
  • Premix burner technology

The Model FLXPM Flextube boiler achieves best-in-class combustion performance with low emissions. Premix burner technology enables the boiler to attain <20 ppm NOx without FGR and <10 CO as standard on natural gas. The modulating burner control automatically adjusts the air/gas mixture for maximum efficiency and optimum turndown.

The FLXPM integrates a servo-driven, fuel-input control valve with air-input control via a variable-frequency-driven fan for precise fuel/air ratio control.

Its compact design makes it easy to fit several units into a boiler room or into a larger hydronic system of condensing or non-condensing boilers. This multi-unit solution helps to divide the load more efficiently in a hydronic or in a steam process.

Because there is no requirement for FGR piping from the stack to the burner, it is easy to incorporate the FLXPM into a new or existing boiler system.
