• Burners with alternate natural gas/fuel oil supply.
• Operation with two progressive power stages.
• Possibility of power modulation operation with installation on
PID modulation automatic regulator control panel (to be ordered
separately with the specific modulation kit).
• Ability to operate with any type of combustion chamber.
• Air-gas mixing at blast-pipe and high pressure mechanical
atomisation of fuel using nozzle.
• Possibility to obtain great combustion values through combustion
air and combustion head regulation.
• Easier maintenance thanks to the possibility to remove the
mixing and atomization unit without separating the burner from
the boiler.
