Model CBEX

The CBEX boiler uses advanced engineering, including Computational Fluid Dynamics (CFD), to optimize components like the burner, furnace, and tubes, ensuring balanced heat release and reduced thermal stress. Exclusive EX system tubes enhance heat transfer by 85%, achieving higher efficiency in a compact design. An optional stack economizer recovers flue gas heat to preheat feedwater, reducing fuel consumption. The LevelMaster low-water cutoff provides the safest pump control available.
