Cleaver-Brooks Firetube Hydronic Boilers
The
Model CBEX
Using advanced engineering methods, design engineers designed the CBEX to optimize every component of the boiler, including the burner, the furnace, and the tubes, in order to provide optimally balanced heat release zones and minimizing thermal stresses in the boiler. Extended heat transfer tubes only found in EX systems uses Computational Fluid Dynamics (CFD) calculations to optimize the geometry of the tube and increase heat transfer by 85%. The result of the advanced heat transfer design is higher efficiency in a smaller footprint. Reduce fuel use with the optional stack economizer by recovering waste heat from flue gases and using it to preheat boiler feedwater. The LevelMaster low-water cutoff and pump control is the safest control available.

- 50 to 800 HP
- 4 Pass
- Natural gas/propane, #2 and #6 oil, combination
- Alternate fuel capability
- Waterback or Dryback design
- 60 ppm, 30 ppm, 9 ppm and 5 ppm NOx emission rates are available
Model CBJT
The CBJT is a complete package, including pressure vessel, integral burner, and controls. Engineered by Cleaver-Brooks to be a fully compatible boiler and burner package featuring excellent fuel-to-steam/water efficiency, space savings, and low emissions. It is ruggedly contructed for hot water or low and high-pressure steam applications. For customers who prefer the jet burner design, the CBJT provides the highest value, with a focus on safety, ease of maintenance, lowest emissions and the flexibility to add desired options to further enhance the package. Upgrade or retrofit your system with Cleaver-Brooks controls, economizers, water treatment systems, and all the other system components to build a state-of-the-art boiler room of virtually any size and capacity.
