Low NOx

Air intake.
Ventilation compartment ®
The new high-performance internal
recycling ventilation system, makes
these burners highly adaptable on all
boilers, enabling:
• Faster combustion stabilization
during startup.
•
Reduced pollution emission in
compliance with European
regulations.
• Extremely low noise level (isolated
air system) that can be further
reduced through the use of an
optional louvre.
• Thermal output between 90 and
94%, according to the type of boiler.
In addition, the linear air shutter (volet
d’air ® ) simplifies and improves
adjustments.
Main air
intake.
Multiple air intakes cool the fan motor
and ensure a continuous supply of
combustion air.
Integrated electrical ®
compartment
Air intake.
The electrical components are installed
in a compartment isolated from the air
circulation and dust. This ensures that
these burners are IP 54 compliant.
These burners are IP 54 only with the
transparent plastic cover.
This highly accessible compartment
contains:
• security box,
• ionization current measuring point,
• RS.232 socket,
• motor-fan contact switch,
• air shutter servomotor,
• ignition transformer,
• terminal board and automatic control
switches,
• nine cable entries with cable glands,
• space to insert the speed variator:
Variatron ® ,
•
control panel seen through a
detachable window, including:
Start-Stop switch, local-distance
switches, Auto-Manu, pushbutton for
manual output adjustment and
control circuit fuse,
• position for output regulator,
•
real-time display screen showing
data from the MDE ® system.
