CLEAVER-BROOKS CLEARFIRE CONDENSING HIGH EFFICINCY HOT WATER BOILER

The Clearfire, model CFC, satisfies economic and environmental demands for today. It features a combustion system with pre-mix down firing burner, which is fundamental to achieve efficiencies up to 99% and NOx levels to less than 20 ppm. Using natural gas and propane the Clearfire CFC is suitable for central heating and indirect hot water supply for working pressures up to 3 bar or 5bar depending on output required.
* Rugged stainless steel construction with 20 year thermal shock guarantee
* Ultra-high performance (full condensing) with efficiencies to 98%
* Fully modulating burner with variable speed fan
* "Whisper" quiet operation with a decibel rating of <70 dB at high fire
* Low emissions; NOx levels to sub-20 ppm
* Sealed combustion capability
* No minimum flow or water temperature requirements
* Low waterside pressure drop

CLEAVER-BROOKS Clearfire - Steam, 10-40HP

The Clearfire-H's high efficiency is achieved by employing an advanced Fecralloy burner designed to premix air and fuel for optimal combustion. This boiler utilizes Cleaver-Brooks' patented Alufer finned firetubes resulting in unmatched heat transfer and superior fuel-to-steam efficiency. Efficiency is 85% on low pressure steam. With optional economizer efficiency is 85% on high pressure steam.
* Fully-modulating with High-turndown with variable speed blower
* Easily tuned, zero-governor, premix burner - no dampers or linkages
* Low emission (<30 ppm and ,10 ppm CO) - advanced combustion design eliminates need for flue gas recirculation
* High efficiency for greenhouse gas reduction
* Direct spark ignition
* Low gas pressure <14" W.C.
* Quiet operation < 70 DBA
* Single phase power - 115V or 230V
* Natural gas (UL) or propane
* Controls are CSD-1 compliant
* 15# or 150# steam

C-B Pro-Fire is a leading line of burners and components specially designed for commercial, industrial and institutional applications. Customers around the world trust C-B Pro-Fire products because Cleaver-Brooks continues to deliver on The Power of Commitment to produce maximum efficiency and durability.
According to the Department of Energy, almost 80 percent of boilers in the United States are nearly 30 years old or older. If replacing a boiler isn’t an option due to budget constraints or, the boiler’s pressure vessel is in excellent shape, there are other ways to improve efficiency. Retrofitting an old boiler can bring its performance up to par with today’s new systems. Minimize energy losses and maximize fuel savings with a new burner and/or boiler/burner management controls.

PATTERSON-KELLEY BOILERS
MACH HIGH EFFICIENCY CONDENSING BOILER

Sizes available are 300 MBH to 2000 MBH.The Patterson-Kelley condensing hot water boiler is certified at 92% efficiency based upon the operating conditions specified for testing under ANSI Z21.13/CSA 4.9. The efficiency for a condensing boiler changes with three key factors: water flow rate, entering water temperature, and firing rate. Note that under certain operating conditions the efficiency can be as high as 99%!
PK Modu Fire Forced Draft Modulating Boiler

Track partial loads with smooth 5:1 turndown and up to 88% Efficiencies.
Sizes available are 1000 MBH, 1500 MBH, and 2000 MBH.
This is a true "forced draft" process. The combustion chamber is pressurized using a variable speed blower, and there is sufficient presssure to pressurize teh breeching the breeching and chimney as well. Higher pressure means smaller chimney sizes (6" & 8" available), which reduces installation costs to increase your savings.
All of this - together with its small footprint, light weight, industry-leading warranty and enhanced control functionality as standard equipment - makes the Modu-Fire FD the most friendly hot water boiler on the market today.
