RBI expands line of Torus boilers

December 18, 2023  By  Doug Picklyk

RBI has expanded the Torus line of watertube boilers and water heaters to include smaller sizes from 300 -1000 MBH.

The full line is now ranges from 300 – 4,000 MBH.

Torus boilers include the HeatNet 3.0 digital touchscreen control and Tru-Flow fuel/aircoupling system. The Torus uses a pressure-driven air/fuel mixing system to reliably provide up to 10:1 turndown without any negative effects, including ignition lockouts.


An available rack system for stacking 300 – 1,000 MBH units allows for space saving flexibility.

The Torus heat exchanger is made from industrial grade 316L stainless steel, very resistant to both thermal shock and acidic condensate.
