GENERAL FEATURES

This series of industrial burners is designed for all those applications that require big-sized air fans or air-flue heat exchangers to be
installed in sound-proof areas to reduce noise. They can be provided with built-in or separately-mounted control panel (console or wall-
mounted).

The gas coming from the supply line, passes through the valves group provided with filter and stabiliser. This one forces the pressure in
the utilisation limits. The electric servocontrol (2), that moves proportionally the air damper and the gas butterfly valve, uses an adju-
sting cam (1) with variable shape. This one allows the optimisation of the gas flue values, as to get an efficient combustion. The combu-
stion head positioning determines the burner’s output. The combustion head (11) determines the energetic quality and the geometry of
the flame. Fuel and comburent are routed into separated ways as far as the zone of flame generation (combustion chamber). The air
(comburent) and fuel (gas) are forced into the combustion chamber.
