WESTFIELD, Mass. — RBI introduces Torus water tube condensing boilers and water heaters designed to bring next-level performance in a compact footprint. Offered in sizes ranging from 1,250-4,000 MBtuh, Torus boilers are up to 97.5% and water heaters are up to 98% Air-Conditioning, Heating, and Refrigeration Institiute (AHRI)-certified efficient. Torus units feature a 5:1 turndown for outstanding performance and quality in a user-friendly design.
At the heart of Torus is the heat exchanger. 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. The unique four-pass design works in concert with a multichannel manifold and increased tube diameters resulting in ultra-high efficiency with very low pressure drop. An exclusive telescoping burner door system slides outwards offering full access to the combustion chamber for annual inspection and service.
