Cleaver-Brooks First to Achieve AHRI Certification for 12,000 MBTU/hr Condensing Boiler

Thomasville, Ga: April 13, 2018

Cleaver-Brooks announces that it is the first manufacturer to earn AHRI certification for its ClearFire®-LC (CFLC) 12,000 MBTU/hr hydronic condensing boiler, and it is only the second manufacturer in the industry to earn AHRI certification for a 10,000 MBTU/hr hydronic condensing model. The CFLC 12,000 model earned a combustion efficiency rating of 94.5% and a thermal efficiency rating of 94.5% in independent, third-party tests certified by AHRI. The CFLC 10,000 model achieved the same ratings.

Now, all CFLC models are AHRI certified. Available in sizes ranging from 4,000 to 12,000 MBTU/hr, the CFLC boiler achieves up to 98% efficiency. It features an integrated premix gas burner and linkageless control that work together to provide full modulation, high turndown, and ultra low emissions to 9 ppm NOx.

Cleaver-Brooks also earned AHRI certification for all models of its recently launched ClearFire-CE (CFC-E) boiler. The CFC-E ranges in size from 500 to 2,000 MBTU/hr and achieves up to 99% efficiency. Named a finalist in the 2018 AHR Expo Innovation Awards, the CFC-E features dual temperature returns, enabling maximum operating efficiencies in a variety of system applications. There are no flow limitations to consider and no need to satisfy multiple-boiler design constraints, allowing for system engineering flexibility and maximum boiler efficiency.

All ClearFire condensing boilers are engineered in a high-mass firetube design and utilize extended-heating surface AluFer® tubes to achieve industry-high efficiencies.

The Air Conditioning, Heating and Refrigeration Institute (AHRI) administers the AHRI Certification Programs that test and certify the performance of HVACR and water heating equipment. Its industry-respected approach to product certification requires the performance of equipment in the program to be independently measured and verified, allowing for fair product comparisons.
