P-K MODU-FIRE FD N2000 in practice

Patterson-Kelley's submittal prints the N2000MFD at 2,000 BTU/hr input and 1,700 BTU/hr output and 5:1 turndown. Design data: 160 psig max pressure, 250°F max allowable temperature, 220°F max setpoint, 50.8 boiler HP, 206 sq. ft. heated wet surface and 170 GPM flow at 20°F ΔT.

Connections are a 1 1/2" NPT-F main gas, 2 1/2" NPT (supply F / return M) supply/return, a 8" dia. stub combustion-air inlet and a 8" (6" with adapter) exhaust vent. Shipping dimensions are 54" × 32" × 68" (L×W×H); operating weight is 985 lb, shipping weight 990 lb and water content 7.3 gallons. The submittal lists ASME CSD-1, FM Global 6-4 and GE GAP (IRI) compliance and an integrated NURO-series control.

P-K describes the MODU-FIRE FD as a full-modulation forced-draft design that 'changes both fuel and air at a constant ratio to match boiler output to actual heat demand' with smooth 5:1 turndown tracking down to 20% of rated capacity and up to 88% efficiency. No official Canadian-sales statement was found, so canadianStatus stays unknown.

Best suited to

  • Commercial plants documenting an installed MODU-FIRE FD N2000 against P-K's submittal
  • Hydronic systems in the 2000 MBH input class
  • Retrofit projects that need a small-footprint forced-draft boiler
