Burners for light-oil two stages progressive (hi-low flame) or modulating (PID fully modulating) if equipped with
addition of optional modulation kit and probe.
Composed by: 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.
The adoption of strong metal components makes the burner durable also in heavy duty conditions.
Complete of flange and gasket for installation on generator, nozzle, flexible pipes and line filter.
The actuators are independent and are managed directly by the electronic cam:
- one actuator for the air shutter
- one actuator for the light-oil modulator
The burners are equipped with an electronic microprocessor system, in addition there is a LCD display with
interactive configuration.
With the addition of optional accessories (probes) thanks to the most advanced systems for automatic
modulation, the burner constantly ensures the proper fuel / 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.
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.
Some accessories are available, like: PC interface, VSD (inverter), Profibus, Modbus.

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.
