FPH VERTICAL FIRETUBE
This boiler provides up to 86% efficiency and capacity is 330 MBH to 4,100 MBY (9.5 BHP to 120 BHP). This is a common vertically designed unit with better efficiency as a result of having an under-fired power burner. With its simple 4 piece configuration, the unit offers the advantage of greater water volume which results in both a low pressure drop thru the unit and reduced cycling for overall efficiency.
The FPH can fit where space is limited, can be easily installed and serviced, and can be designed to communicate with any building management system. Options include construction under ASME Section I/VII for high temperature hot water applications and other features include a single pass heat transfer area of 4 sq. ft. per BHP. The unit consists of a combustion chamber, pressure vessel, combustion gas collector with flue, and a cabinet and is available in low NOx designs as low as sub-9ppm.
