Condensing CFC-EThe 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.

Features:

  • True counterflow-arrangement heat exchanger for maximum heat transfer
  • High-mass design in a compact footprint, ideal for retrofit applications
  • Duplex stainless steel combustion chamber, tubes and tubesheet offer excellent corrosion resistance
