Serie TBG ME

Technical and functional features

• Gas-fired burners, EN676.
• Two-stage progressive/modulating operation.
• Ability to operate with output modulation by means of automatic RWF40 regulator mounted on the control panel (to be ordered separately with the modulation kit).
• 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.

TBG 45 - 60 ME

• Low NOx and CO gas-fired burners, EN676 "Classe III".
• Modulation ratio 1:4.
• Regulation of air flow rate for first and second stage with damper closure on standby to prevent in-flue heat dispersion.
• Gas adjustment gas by throttle valve controlled by electronically controlled step servo motor.
• Tightness gas valve control, EN676.
• Comes with 4 and 7-poles connectors, 1flange and 1 insulating seal to connect the burner to the application.

TBG 85 - 120 - 150 - 210 ME

• Partial combustion gas recirculation blast-pipe with low NOx emissions (class II).
• Ambidextrous hinged combustion head allowing an easy maintenance access without removing the burner from the boiler..
• Air capacity adjustment by means of linear opening damper using electronically controlled step servo motor.
• Automatic closure of the air damper during stand-by..
• Electrical panel that connects by 4 and 7 pole plugs/sockets provided.
• Electrical panel with protection rating of IP 55.
• Sliding boiler coupling flange to adapt to the head protrusion of the various types of boilers.
• High turndown ratio (1:5).
