Two benefits of the modular, once-through, watertube design include the ability to rapidly generate full steam, even from a cold start (on-demand steam), and functionality that allows boilers to turn off quickly according to current load requirements.
Developed for use with a variety of boiler types, such as firetube and watertube boilers, this burner series is capable of less than 30-ppm NOx emissions without flue gas recirculation (FGR).
A 52,000-square-foot, seven-story building was transformed from an office facility into 65 one- and two-bedroom rental units. The contractor accomplished this using Stainless Vertical Firetube condensing boilers.
