F.B.R. Low NOx Two-Stage Sliding or Modulating Gas Burners

F.B.R. Low NOx 2-stage sliding and modulating gas burners provide high-efficiency flame control with Class 4 emissions, supporting industrial boiler systems with clean combustion performance.

Product Overview

F.B.R. Low NOx gas burners with sliding or modulating control are engineered for industrial systems that require precise combustion and reduced environmental impact. Designed for operation with either mechanical or electronic cam control, these burners meet EN676 Class 4 certification for low NOx emissions (<60 mg/kWh). Each model features a reverse-blade fan, inox steel combustion head, and flexible modulation control — suitable for varying load demands and boiler capacities. All units are delivered preassembled with safety gas trains and offer diagnostic display options on EL variants.
