Navien’s NFB-C Commercial Condensing Fire Tube Boilers have been honored with the Spaces4Learning 2020 New Product Award for Mechanical, Electrical & Plumbing – HVAC, Platinum and the FacilitiesNet 2020 Vision Award for HVAC.
The Spaces4Learning New Product Award program honors the outstanding product development achievements of manufacturers and suppliers whose products or services are considered to be particularly noteworthy in their ability to enhance the learning environment.
The FacilitiesNet Vision Awards honor innovation and excellence in products that contribute to the efficient and profitable operations and management of institutional and commercial buildings in the United States. An independent panel of facility executives reviewed and judged Vision Awards entries.
Navien’s NFB-C commercial condensing fire tube boilers received these awards for their industry-leading 97.5% thermal efficiency which lowers operating costs for building owners, superior product engineering and numerous advanced features and benefits.
Each NFB-C boiler uses a stainless steel heat exchanger that is form-pressed and robotic laser welded to minimize the number of weak points that could be prone to thermal stress and corrosion. Oval shaped tubes within the heat exchanger contain internal turbulators designed to improve both the heat transfer rate and the structural integrity of the assembly. A specific water flow is generated by baffles inside the heat exchanger to extract the maximum amount of heat from flue gasses while the non-metallic base provides additional protection against corrosion caused by acidic condensate.
More advanced features of NFB-C boilers include top and bottom piping connections for installation flexibility and an advanced 7-inch color touch screen display with easy intuitive navigation for setup, troubleshooting and operation. The sophisticated gas flow control systems offer up to a 15:1 turndown ratio and extremely low NOx levels, certified by SCAQMD to meet the most stringent code requirements. Low exhaust gas temperatures allow the NFB-C to be installed using multiple venting options including PVC, CPVC, polypropylene and stainless steel. NFB-C can be installed with 3” venting up to 60 feet or 4” venting up to 150 feet.
Optional accessories allow each NFB-C boiler to connect to building management systems through Modbus, BACnet or LonWorks protocols. NFB-C boilers are NaviLink wi-fi remote compatible, cascade capable up to 16 units, common venting capable up to 4 units and are certified for high-altitude installations up to 10,100 ft.
