FTH, FLEXTUBE GAS/OIL FIRED HOT WATER BOILERS
HIGH EFFICIENCY BOILERS FOR HEATING OR PROCESS APPLICATIONS
Sizes Range From 25 BHP- 500 BHP
(1050 MBH- 21,000 MBH lnput)
• PRECISION FTH Series are “Flex-Tube” forced draft hot water boilers noted for their small footprint and high fuel-to-output efficiency, exceeding 82%-85% for gas and 86% for oil.
• PRECISION FTH Series Boilers utilize 1 1/2″ OD tubes in a serpentine tube corfiguration designed to absorb thermal shock. The pressure vessel is warranted against thermal shock damage for a period of 25 years. This design accommodates up to 150ºF temperature differences from the supply and return, offers virtually instantaneous hot water.
• PRECISION FTH-1thru 3 Series Boilers 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.
• PRECISION FTH-4 thru 6 Series Boilers the fumace is fully water cooled on all four sides.
• PRECISION FTH Series hot water boilors are designed with the return in the lower header and the supply in the upper header. This allows the water to circulate equally through the tubes with positive circulation.
