CB Boiler Model CFC-E
The ClearFire-CE (CFC-E) is a compact, high-mass, fully condensing hydronic boiler, capable of variable-flow pumping, allowing for maximum operating efficiency in a variety of system applications.
- Fully condensing high-mass firetube boiler
- Compact footprint
- 500 to 2,000 MBTU
- Standard less than 20 ppm NOx
- Variable flow capable with no minimum flow requirement
- Standard dual-return connections
Product Overview
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 5:1 fully modulating turndown without the use of complex air/fuel mixing valves or mechanical devices.
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.
