Serie BTG ME

Technical and functional features

• Two-stage progressive output 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.
• Air-gas mixing at blast-pipe.
• Ability to obtain optimal combustion values by regulating combustion air and blast-pipe.
• Combustion head at partial recycle of combusting gas which allow to achieve low Nox emissions (Class II for BTG 15 ME and class III forBTG 20 ME of the european norm EN267).
• Capacity regulation of the combusting air with automatic closing gate during pause to avoid heat losses at the chimney.
• Maintenance facilitated by the fact that the mixing unit can be removed without having to remove the burner from the boiler.
• With valves seal control device added.
• Comes with 4 and 7-poles connectors, 1flange and 1 insulating seal to connect the burner to the application.

Design features

• Light die-cast aluminium ventilation unit.
• High performance centrifugal fan.
