The ClearFire®-CE (CFC-E) is a fully assembled, high-mass firetube condensing boiler with a large-water-volume pressure vessel. The high-mass design equates to a low pressure drop, reducing pumping energy with no minimum flow requirements. The pressure vessel is also thermal shock proof, capable of high-delta-T system designs to maximize condensing and reduce flow rates. The highly effective fireside heating surface with industry leading AluFer® tubes leads to superior efficiencies in all operating conditions. The modulating, premix burner control automatically adjusts the air/gas mixture for maximum burner efficiency. The linkageless burner provides fully modulating turndown without the use of complex air/fuel mixing valves. The dual-return connections have the ability to increase condensing in the boiler and raise efficiencies by 6%+ more than a single-return boiler. The ClearFire-CE provides the reliability and longevity that customers expect from Cleaver-Brooks. The CFC-E is designed to leverage the advantages of primary-variable-flow pumping systems with a small overall footprint, offering system flexibility and true operational efficiency without compromise.
