RBI FlexCore - Symmetrical Firetube Boilers
FlexCore Symmetrical Firetube Boilers by RBI are engineered for optimal hydronic heating performance, boasting superior efficiency and durability compared to other firetube boilers. These boilers offer a highly balanced heat exchanger design that minimizes temperature variations and thermal stress. This ensures a minimal temperature difference across the heat exchanger, preventing intra-tubular stresses often present in competitive models. The FlexCore's piston-like heat exchanger mitigates expansion and contraction due to temperature changes, contributing to exceptional durability. The system's Turbo Pilot ignition offers reliable operation even under variable gas pressures. With the advanced Symmetric Air/Fuel Coupling, the boilers adjust fuel input to maintain an optimal air/fuel mixture, enhancing combustion efficiency while keeping emissions low. These boilers integrate seamlessly with the HEATNET Boiler Management System, allowing for remote monitoring and precise control. The compact design reduces space requirements while ensuring long-lasting performance and efficiency.
FlexCore Symmetrical Firetube boilers bring hydronic heating products to unprecedented levels of operating efficiency.
Unlike other manufacturers; from start to finish the FlexCore was designed, developed and engineered by the experts at RBI.
Engineered for performance and longevity the FlexCore utilizes a perfectly temperature balanced heat exchanger that provides not only the highest efficiencies but also a durability beyond that of any competitive firetube boiler on the market.
