Burnham MPC (Multi-Pass Commercial) Brochure

MPC 

MULTI-PASS COMMERCIAL BOILER

•

  Thermal efficiencies of up to 87% without the use of a secondary, 

condensing heat exchanger provides for exceptional fuel savings

•

 Capable of extremely low NOx operation—less than 9 ppm

•

  Fully compliant with LEEDS® building standards, MPC is the most 

environmentally friendly commercial boiler on the market

•

  Advanced 3-pass cast iron sections engineered and manufactured 

in the U.S.A., designed to maximize heating system efficiencies 

and provide substantial energy savings over single-pass boilers  

•

  MPC sections are assembled with Burnham Commercial’s proven 

cast iron nipple construction that does not degrade with heat, 

thus eliminating any concerns associated with competitive 

section sealing techniques

•

  Advanced high-temperature silicon-coated rope gasket is 

compressed into a tongue-and-groove area cast into each boiler 

section to ensure a durable, gas-tight seal between sections

•

  Left or right opening, provides unobstructed access to the 

combustion chamber and all flue passages 

•

 Optional cover panels provide a sleek look

American-Made Cast Iron Construction  
Burnham Commercial’s unique eutectic cast iron has an extremely 

high silicon content, making it stronger and more flexible 

–  Offers better thermal shock resistance and greater heat 

transfer capabilities than other cast iron products  

•

  Designed to operate at unprecedented 80°F minimum return  

water temperature

– Minimum supply water temperature is 130°F  

– Maximum water temperature differential (∆ T) of 80°F

•

  Equipped with integral return water mixing tube (RWMT) that 

evenly distributes the return water into each section  

•

  No need for external mixing devices or complicated piping, 

saving installation time and money 

•

  Standard 4-inch insulation on all sizes reduces jacket heat loss, 

reduces boiler room temperatures and helps increase efficiency

•  Jacket side panels interlock and mount to the frame  

without screws 

•  A concealed chaseway, located in the top panels, hides wiring  

for a clean, modern appearance 

•

 The MPC is optimized for “full modulating” operation

– Also available for low-high-low firing

•

SBC comes integrated into the Power Flame or Beckett burner 

control panel to provide unsurpassed boiler and system control

– Factory installed SBC modules are UL Listed

•

 Only American-made commercial cast iron boiler with UL Listing

•

 Standard on factory packaged / firetested MPC boilers

•

 Safety benefit, virtually unmatched in the industry
