THOMASVILLE, Ga.  Cleaver-Brooks announced 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 percent and a thermal efficiency rating of 94.5 percent 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 percent 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 percent 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.
