Triple-Flex ultrahigh-efficiency condensing flexible-water-tube boilers offer guaranteed minimum thermal efficiency of 90 percent even in worst-case condensing-boiler operating conditions, such as 160°F return water and 180°F supply water at maximum input. Efficiencies of 99 percent are achievable with lower return-water temperatures. —Bryan Steam LLCIntegrated boiler system
The MTH series of burners includes full modulation with parallel positioning. It is available in natural-gas and propane models from 2.5 to 16.0 MMBtuh. It is capable of low-NOx/CO emissions without flue-gas recirculation (FGR), making it well-suited for boiler or process-heating applications where low emissions are required and FGR is impractical or inaccessible. —Industrial CombustionBoiler-reset control
