Torus compact units are available in sizes ranging from 1250 - 4000 MBH with AHRI certified efficiencies.
RBI Torus condensing watertube boilers and water heaters now feature 10:1 turndown, further optimizing performance efficiency. Utilizes a pressure-driven air/fuel mixing system to reliably provide up to 10:1 turndown without the negative effects often seen in high turndown systems.
Pressure-driven system has no moving parts and eliminates common nuisance failures including ignition lockouts. Torus compact units are available in sizes ranging from 1250 – 4000 MBH with AHRI certified efficiencies of up to 97.5% on Boilers and 98% on water heaters.
Made from 316L stainless steel, Torus heat exchangers are manufactured through a process called tube hydroforming which allows the shaping of stainless steel tubes that are not only stronger and lighter but also have a higher quality surface than competitive heat exchangers. Additionally, the 4-pass design works in concert with a multi-channel manifold and increased tube diameters resulting in ultra-high efficiency with very low pressure drop.
