CONDENSING BOILERS
CHEYENNE
General Description
This High-Efficiency Condensing Boiler is one of the largest condensing boilers in the industry, available as true dual-fuel natural gas and oil unit.
Features
- Choice of UL Listed Burner Packages
- Proven Efficiency
- NOx Emissions of 30 PPM or less available on all firing rates, now with sub-7 ppm NOx levels for dual fuel units up to 7.0 MMBTU/hour with Weishaupt's ULN burner.
- True Dual Fuel Capabilities with Natural Gas/Oil
Construction
- Large furnace with daviated rear lid access for allowing access to furnace & burner combustion head without disturbing the burner or fuel train.
- 12GA customized tubes in the 2nd pass with rifled tube design to allow for increased heat transfer
- Stainless steel tube in the condensing section, including full length turbulators, allowing for increased heat transfer while not impeding the flow of condesate
Quality
- Full penetration tube welds with all tubes completely welded to tubesheets using full penetration wels to withstand thermal stress caused by cold return water and up to 100° Delta T.
- Large waterside volume that eliminates the need for a dedicated circulating pump or high minimum flow. Even with a no flow condition, water temperatures will not exceed safe conditions. This large volume allows for load fluctuation with fewer burner cycles resulting in better overall performance.
