ELECTRONIC CONTROL BOX
K X5/M/2 EL
Dual fuel gas/light-oil burners with electronic control box.
Gas fuel operation: two stages progressive or modulating operation (if equipped with addition of optional
modulation kit PID and probe; to guarantee an ideal proportionality of the power supplied to the thermal load).
Light-oil fuel operation: two stages.
Composed by: aluminium frame, fan at high pressurisation and combustion head with adjustment at high efficiency
and high flame stability.
Compact overall dimensions and disposition rationalized of the components with accessibility facilitated for the
operations of setting and maintenance.
Available in the versions METHANE (natural gas) or L.P.G. (to specify at the order) on demand specific versions for
town gas, coal gas or biogas.
Gas train complete with: work valve with adjustment, safety valve, minimum gas pressure switch and filter.
Complete of: flange and gasket for installation on generator, nozzles, flexible pipes and line filter.
The servomotors are indipendent and managed directly from the electronic control box of the burner: one
servomotor for the gas modulator and one servomotor for the air shutter.
The burners are equipped with a display that allows to:
- adjust the operating parameters of the burner
- visualize the flame intensity
- adjust the operating curve of the burner (air / gas ratio)
With the addition of optional accessories (probes) thanks to the most advanced systems for automatic modulation in
mechanical or electronic version, the burner constantly ensures the proper gas / air ratio. The maximum efficiency of
the returns in each combustion point derived from the punctual adaptation of the thermal load to the heat
requirements of the burner at any instant of operation.
In the version with the electronic cam the fuel / combustion air curve, more extended, is fully exploited,
guaranteeing excellent performance in terms of accuracy and speed, even during the calibration phase.
A microprocessor monitors the different stages of the process and allows the correct repetition of the sequences of
operation.
Optional accessories: PID power modulator kit, probe, PC interface, VSD, O2 control, O2 + CO control, field bus
(profibus, modbus, profinet).

The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the burner to the
boiler. For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case of non-
compliance, contact the manufacturer.

FLAME TUBE LENGTH
Flame tube length must be selected based on the specifications supplied by boiler manufacturer and, in any case, it
must be greater than the thickness of the boiler door included its insulation. In case of boilers with flame inversion or
front flue combustion chambers, it is necessary to insulate the area between the flame tube and front door with
refractory material. This protection material must not impede flame tube extraction.
