Thanks to many years of experience in the design and manufacture of Burners, Riello has developed a new range of medium power burners, the New RS ULX Series, based on the patented ULX (Internal gas Recirculation) low emission technology, suitable to achieve NOx emissions lower than class 4 of the EN 676, without any need of FGR system, with proper combustion chamber dimensions.

RS 68-200/EV ULX burner series covers a firing range from 150 to 2400 kW, and it is based on the Digital Burner Management System Riello REC37 or Siemens LMV52, which can manage the air-fuel ratio by independent servomotors in order to obtain a perfect output control and to assure a correct combustion and safe operation on all modulation range.

Operation can be “two stage progressive” or, alternatively, “modulating” with the installation of the dedicated probe (with burner models equipped with REC37 control box, an additional PID logic regulator is required).

RS 68-200/EV ULX burner series guarantees high efficiency levels in all the various applications, thus reducing fuel consumption and running costs; such models operate with Variable Speed Drive technology base on the control of a Frequency Inverter that modifies the air flow through the motor speed variation. Optimization of sound emissions is guaranteed by the special design of the air suction circuit and by incorporated sound proofing material.

Finally, RS 68-200/EV ULX burner models, equipped with Siemens LMV52 control box and compatible with combustion optimization based on the residual O2 content in the exhaust fumes, are now available.

The new RS/EV ULX range combines exceptional Ultra Low NOx combustion performance to the consolidated features of robustness and reliability of the RS series.
