Serie TBG LX PN

Technical and functional features

• Low NOx and CO gas-fired burners, EN676 "Classe III".
• Two-stage progressive/modulating 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).
• Gas adjustment by proportional working pneumatically controlled valve.
• Compatible with any type of combustion chamber, according to EN303 standard..
• Partial combustion gas recirculation blast-pipe with low NOx emissions (class III).
• High blowing efficiency, low electrical input, low noise.
• Ambidextrous hinged combustion head allowing an easy maintenance access without removing the burner from the boiler..
• Air capacity adjustment with linear opening controlled by electric servo motor.
• Automatic closure of the air damper during stand-by..
• Fan speed adjustment in relation to changes in burner demand provided by means of inverter, to obtain a significant reduction in noise levels and electricity consumption (version V only).
• 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.
• Gas train inlet can be mounted either upward or downward.
