The P-K MODU-FIRE® Forced Draft boiler is a full modulation design that changes both fuel and air at a constant ratio, matching boiler output to the actual heat demand.
With a constant fuel to air ratio, and smooth 5:1 turndown that can track varying loads down to 20% of rated capacity, efficient and clean combustion can be achieved across the entire firing range of the boiler.
All of our boilers are equipped with the most intuitive interface in the industry, the NURO® Touch-Screen Control. Designed to maximize efficiency, the NURO® Control System monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature.
