The Series 4S uses the very latest design techniques and standards. This means it is designed for low volumetric release rates and produces a higher efficiency due to the larger furnace and higher heat transfer design. The 4S is also a great option for low NOx applications.

Latest Design Techniques
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 fi ring using any selected burner vendor. The Series 4S is also easily converted to a low NOx product when needed.
Higher Efficiency
The Burnham Series 4S design produces a higher effi ciency due to the larger furnace and higher heat transfer design. To determine the effi ciency of your next job, contact your local Burnham representative.
