Bryan Steam’s new trio of Triple-Flex, ultra-high-efficiency, condensing “flexible water tube” boilers offer a guaranteed minimum thermal efficiency of 90 percent in worst-case condensing boiler operating conditions, such as 160-degree F return water and 180-degree F supply water at 100 percent firing load. Efficiencies up to 99 percent are achievable with lower return water temperatures as found in new building designs. The TF 150, TF 200 and TF 250 models offer inputs from 1,500 to 2,500 mbh with sub-30 ppm NOx using a hybrid metal fiber burner.
