Description

The Series 4S uses the very latest design techniques and standards. Its furnace, the workhorse of the boiler, is designed for low volumetric release rates of no more than 136,000 btu/hr/cu.ft. The lower the release rates, the “easier” your boiler works. As your boiler works easier, less stress is put upon the steel, tube ends, refractory, etc., resulting in a longer lasting boiler. In addition to longevity, a larger furnace makes for ease in firing using any selected burner vendor. The Series 4S is also easily converted to a Low NOx product when needed. The Burnham Commercial Series 4S design produces a higher efficiency due to the larger furnace and higher heat transfer design.
