The series covers a firing range from 1070 to 9580 kW, and they havebeen designed for use in hot water boilers or industrial steam generators.Adjustment is modulating, through an innovative electronic module, which gives control ofthe air/fuel ratio and PID control of the generator temperature or pressure.The mechanisms of regulation allow to catch up a high modulation ratio on all firing ratesrange.The burner can, therefore, supply with precision the demanded power, guaranteeing a highefficiency system level and the stability setting, obtaining fuel consumption and operatingcosts reduction.An exclusive design, with fan unit fitted on line with the combustion head, guarantees lowsound emissions, reduced dimensions, easy use and maintenance.TS0019UK03
