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.
Models: N750, N1000, N1500, N2000, N2500, N3000
