Burner range extended

These new models build on the features of the R Series with key advances in power output control and ventilation. Suitable for gas, light oil or dual fuel application, advanced combustion technology ensures low NOx levels conforming to Class 3 EN 676.

The new burners are available in various control configurations. These include modulating operation using an electronic cam for closer and more repeatable control of the air-fuel ratio, as well as options for variable speed drive of the combustion air fan motor to reduce energy consumption and noise levels. Integration of O2 trim control ensures the highest achievable combustion efficiency is maintained throughout the modulation range.

As with all Riello products, ease of installation, commissioning and servicing were key considerations in the design, with easy access to internal components offered by the hinged access to the burner head.
