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 available in sizes ranging from 300-4000 MBH making this unit ideal for a wider array of applications. Torus continues the RBI tradition of high quality and performance in a design incorporating all industry proven components including HeatNet 3.0 digital touchscreen control and our Tru-Flow fuel/air coupling system, making it the perfect solution for all types of installations, the company states. Torus utilizes a pressure-driven air/fuel mixing system to reliably provide up to10:1 turndown without the negative effects often seen in other high turn down systems. 

Torus are +97.5 AHRI Certified, with 300 – 1000 MBH boiler units Energy Star Certified.  An available rack system for stacking 300 – 1000 MBH units allows even greater space saving flexibility.
