Low NOx and CO gas-fired burners, EN676 "Classe III".
Two-stage progressive output operation.
Ability to operate with output modulation by means of automatic RWF40 regulator mounted on the control panel (order separately with the specific modulation kit).
Compatible with any type of combustion chamber.
Air-gas mixing at blast-pipe.
Burnt gas recycling blast-pipe able to achieve very low pollutant emissions, particularly with regard to nitrous oxides (NOx).
Ability to obtain optimal combustion values by regulating combustion air and blast-pipe.
Maintenance facilitated by the fact that the mixing unit can be removed without having to remove the burner from the boiler.
Minimum and maximum air flow regulation for first and second stage by means of electric servomotor with pause closure of gate to prevent any heat dispersion to flue.
Control of the number of fan revolutions according to variation of demand from burner via frequency converter to obtain a significant reduction of noise and electricity consumption (version V only).
Tightness gas valve control, EN676.
Comes with 1 insulating seal to connect the burner to the application.
