ClearFire®-CE (CFC-E) Condensing Boiler – Cleaver-Brooks
Cleaver-Brooks has launched the ClearFire®-CE (CFC-E) condensing boiler. The company says the boiler can achieve up to 99% efficiency due to its enhanced AluFer® firetube heat exchanger and dual temperature returns. When utilized, dual temperature returns increase condensing in a hot water boiler, raising efficiency by 6% or more compared to a traditional single-return design, according to officials.
A low-emissions premix burner is built into the CFC-E. The self-regulating, gas valve/venturi system, combined with ECM variable-speed blower technology delivers true linear modulation control with optimum turndown for hydronic systems. The burner automatically adjusts for combustion air density changes, resulting in a consistent fuel-air-ratio performance without additional actuators and controls. The CFC-E features the Cleaver-Brooks Falcon control that has a built-in ability to control lead-lag, outdoor air reset, automatic isolation valves, primary pumps, and BMS integration.
