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.

RBI offers a sophisticated solution with its commercial Inverter Air-to-Water Heat Pumps, ingeniously merging hydronic systems flexibility with advanced air-to-water heat pump technology. The product is engineered to deliver efficient heating and cooling, incorporating cutting-edge variable speed inverter-driven compressors and Enhanced Vapor Injection (EVI) compressor technology. This system boasts a high-efficiency condenser designed to perform in extreme climates, making it a versatile choice for commercial applications. By prioritizing energy efficiency and environmental responsibility, this heat pump meets the rigorous standards of tomorrow with readiness today, fulfilling the dual role of heating and cooling through one emitter. This makes it an ideal solution for building owners seeking reliable and sustainable climate control technologies.
