Serie TBG

Technical and functional features

• Low NOx and CO gas-fired burners, EN676 "Classe III".
• Single stage operation (on/off).
• Compatible with any type of combustion chamber, according to EN303 standard..
• High blowing efficiency, low electrical input, low noise.
• 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).
• Maintenance facilitated by the fact that the mixing unit can be removed without having to remove the burner from the boiler.
• Control of comburent air flow.
• Gas regulation by means of a two-stage working valve that is electromagnetically driven.
• Ability to add a valves seal control device to the train.
• Comes with a 7-poles connector, 1 flange and 1 insulating seal to connect the burner to the application.
