Serie BTG P

Technical and functional features

• Two-stage operation (high/low flame).
• Compatible with any type of combustion chamber.
• Air-gas mixing at blast-pipe.
• Ability to obtain optimal combustion values by regulating combustion air and blast-pipe.
• Combustion head with recirculation of combusted gases permitting achievement of very low levels of pollutant emissions, particularly nitrogen oxides (NOx) (class III for BTG 20P and class II for BTG 28P under standard EN676).
• Maintenance facilitated by the fact that the mixing unit can be removed without having to remove the burner from the boiler.
• 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.
• Possibility to chose gas train with valve tightness control.
• Comes with 4 and 7-poles connectors, 1flange and 1 insulating seal to connect the burner to the application.
