Cleaver-Brooks Flexible Watertube Boilers

Whether stand-alone or utilized a condensing/non-condensing hybrid multi-unit solution, the model FLX boilers can share the load to increase efficiency in a hydronic or steam process.

The flexible watertube line of boilers is designed to minimize thermal stress and provide quick response in a compact unit. The FLX Premix enables the boiler to achieve <20 ppm NOx without FGR and <10 CO on natural gas. The Model 5 and Model M5M membrane wall watertube is designed for steam applications up to 500 psig, yet is compact in design.  

Size range: 1,500 – 25,000 MBTU/hr (35-600 HP)
Uses: For rapid response for low/ high-temperature heating and steam process, back up fuel oil and field erectable. Applications include heating for universities, medical facilities, office complexes, and various process applications.
Fuels: #2 fuel oil and gaseous fuels
Efficiency: Up to 88%
