with the introduction of new models to extend their output up to 2700 kW.
The new RS-RL-RLS 250 models, suitable for commercial and industrial applications
such as hot water boilers and industrial steam generators, are the evolution of present
R series and they have been developed to offer a higher output in spite of their compact
dimensions, guaranteeing care for the environment and high performances.
The gas models, available with Low Emissions combustion conforming to the class II of
EN 676 European standard, have “two stage progressive” or “modulating” operation
obtained by Mechanical or Electronic Cam. The gas mechanical cam version are also suitable
