Cleaver-Brooks Steam Firetube Boilers

As the founder of the packaged boiler, Cleaver-Brooks knows all about the power of integration. Today, the rules still apply. Cleaver-Brooks engineers the firetube boiler along with the burner, controls and ancillary components as an integrated package to achieve maximum efficiency and the lowest possible emissions.

The EX models are designed with extended heat transfer tubes that result in even higher efficiencies, lower emissions and a 15% smaller footprint. The CBEX Elite model is the only boiler package to maintain 3% oxygen across the full operating range with 30 ppm NOx performance when using natural gas.
