MC Series Packaged Watertube Boilers

9.5 to 200 BHP

Precision Boilers MC Series boilers are “Flex-tube” forced draft boilers noted for their small footprint and high fuel-to-output efficiency, exceeding 82% for gas and 86% for oil.  

The MC Series boilers utilize 1-1/2” OD tubes (0.105” nom wall thickness) in a serpentine tube configuration designed to absorb thermal shock.  The pressure vessel is warranted against thermal shock damage for a period of 20 years.  This design accommodates up to 150°F temperature differences from the supply and return, offers virtually instantaneous hot water, and can be to full steaming capacity in less than 10 minutes.  

The MC Series boilers also utilize a unique 5-pass tube design with upper and lower headers located on the left or right side.  The serpentine bends insure an even flow of gases through the heat transfer area of the boiler as well as equal water flow.  The serpentine bends also create tangent water walls on all but one side of the combustion chamber.  An upper plenum plate diverts the flue gases to the burner end to facilitate flue gas recirculation.

The MC Series boilers are compact compared to other types of boilers; yet maintain approximately 5 square feet of heating surface per boiler horsepower.  Access for maintenance is required on one side only, and units are available as a right or left hand tube configuration, which, for multiple boiler installations, requires less floor space as the boilers can be set to utilize common access space.
