High-efficiency 3-pass stainless steel condensing boilers designed both for retrofit and new construction projects. Project costs are reduced thanks to the high water content heat exchanger, that requires no minimum flow rate and eliminates the need of a costly dedicated boiler circulator. Best quality materials used for all components guarantee high reliability and longer service life. Large heat-transfer surfaces, a counter-flow heat exchanger design and cold return water temperatures together optimize condensation opportunities. The RTC Series Condensing Boilers could be equipped with two-stage or modulating forced draft burners and premix, that achieve extremely low pollutant emissions meeting the most stringent NOx and CO requirements.
