Navien commercial boiler available in two sizes
Navien launched its commercial-sized fire tube boiler series, the NFB-C. The NFB-C is available in two sizes: NFB-301C (301 MBH) and NFB-399C (399 MBH). Each boiler uses the same in-house heat exchanger technology that was introduced with the NFB series in 2018. The NFB-C series includes top and bottom piping connections for installation flexibility and a 7-in. color touch-screen display. The boilers offer up to a 15:1 turndown ratio. 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 four units and are certified for high-altitude installations up to 10,100 ft.
