The KN-Series uses the durability and heat retention capabilities of cast-iron heat exchangers with state-of-the-art air/fuel delivery systems. Every KN-Series boiler is integrated with Heatnet 3.0 - an innovative, digital Boiler Management System that provides consistency and feedback through digital communication.

The engineers at Mestek have taken the KN-Series and raised the bar even further with the KN-Series Plus. The KN-Series Plus incorporates all of the class leading features of the KN-Series with increased efficiencies.

Torus boilers and water heaters bring next level performance in a small compact footprint to today's applications. The RBI tradition of high quality, performance equipment in a user-friendly design continues with Torus. Incorporating all industry-proven components including HeatNet 3.0 touchscreen cascade control and our Tru-Flow fuel/air coupling system and capacities to 4000 MBH Torus has the solution for all commercial installations.

FlexCore Symmetrical Firetube boilers bring hydronic heating products to unprecedented levels of operation efficiency. FlexCore was designed, developed and engineered by the experts at RBI. Engineered for performance and longevity, FlexCore utilizes a perfectly temperature-balanced heat exchanger that provides not only the highest efficiencies but also a durability beyond that of any competitive firetube boiler on the market.

The gas-fired Futera III brings the field-proven performance of Futera Series boilers and water heaters to even higher levels of efficiency and reliability. Featuring full modulation with 4:1 turndown, the Futera III supplies the precise amount of heat necessary to maintain desired building temperature by matching heating demand without over-firing and wasting energy.

The Futera XLF is designed with 5-to-1 turndown, up to 88% efficiency, and backed by RBI reliability and ease of service. Those are just a few of the ways we are helping you solve today's commercial design challenges. And having double the power in the same compact dimensions - width, depth, and height- doesn't hurt either.

The LCD Dominator Series from RBI offers competitively-priced indoor/outdoor units that meet low NOx requirements, while maintaining superior performance and serviceability. The LCD provides dependable performance in rugged environments and process applications, with a wide 400-2300 MBH range. At the heart of the unit is a sealed combustion chamber that provides the flexibility of using outside air or mechanical room air for combustion. Priced in line with the atmospheric category heaters, the LCD features smaller vent sizes, resulting in a lower total installation cost.

The gas-fired Futera Fusion Series brings the field-proven performance of RBI boilers and water heaters to the ultimate levels of efficiency and reliability. Fusion's innovative design makes it the ideal choice for applications with low operating, return or make-up water temperatures. Unlike most condensing products on the market today which publish the highest efficiencies at the lowest inputs, the Fusion Series can attain efficiencies as high as 99% at full input!

Smith 19HE Series cast iron, pressurized, wet-base boiler/burner units are ideal for light commercial water or steam heating system utilizing No. 2 fuel oil, natural gas, or combination gas/oil. Ten different sizes are available, ranging from 308 MBH to 1750 MBH. series 19HE boilers are available in three ways - knocked down, assembled sections or completely packaged units. All sections are tested and approved for 80psi working pressure as standard equipment.

Design simplicity, quality materials, and meticulous craftsmanship have earned Raypak a rock-solid reputation for reliability. While others busily design cost out of their products, Raypak has continued to engineer dependability in.
