ClearFire-CE is fully condensing high-mass firetube boiler
- Compact footprint – fits through a standard door
- 750 to 2,000 MBTU
- Standard less than 20 ppm NOx
- Variable flow capable with no minimum flow requirement
- Standard dual-return connections
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. 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
- Dual-temperature returns for additional energy savings potential
- Falcon total boiler control with lead-lag capability up to 8 boilers
- Quiet operation, <70 dBA sound level at 3 feet
- Fresh-air inlet connection for direct-vent combustion air
- Low waterside pressure drop for reduced pumping energy requirements
- Hinged burner for easy access
- Thermal shock resistant
- cULus listed
The CFC-E is up to 99% efficient due to its high-mass firetube construction with TurboFer technology. It is simple to install and integrate into a system due to its robust, low flow tolerant design. The burner design and controls offer future-proof fuel flexibility that can support renewable natural gas and up to 20% volumetric mix hydrogen-natural gas blends.
