MAIN CHARACTERISTICS OF THE RANGE
Combustion
Unique and efficient
Developed and improved by ELCO R&D department,
the Free Flame technology is a unique combustion process.
This ELCO technology is capable to reach the NOx levels
required by the most severe standards for all types of
combustion chambers, whether they are 3-pass or reverse
pass boilers.
Switch cabinet
Built-in and modular
All the NEXTRON® burners feature integrated switch cabinet,
the ISC System, with modular concept for control devices and
accessories, including:
• adjusting and safety control box
• EMC protected power circuit of fan motor
• display with command keyboard in front of the panel
The ISC System houses options and accessories, such as the
power regulator and the frequency inverter (Variatron), and
customizes each burner according to the installation needs.
Design
Smooth and integral
The original design of NEXTRON® range is the result
of a successful integration between burner and ELCO
technologies.
NEXTRON® burners are able to perfectly integrate
themselves in any installation and professionals will
appreciate the innovative construction that ease
maintenance.

Communication
User-friendly and universal
The adjusting and reading of the available information about the
NEXTRON® operation are possible through the MDE2 System, a display
with a 5-buttons keyboard, by using pictograms and numerical data.
This user-friendly language assures quick reading and total understanding,
as ever before.
Acoustic
Comfort and compact
The NEXTRON® burner range offers a high acoustic
comfort thanks to the Low Noise System.
The unique air intake channel is carefully designed to
achieve an acoustic level significantly lower than
80 dB(A) up to 10 MW.
This integrated and patented system on all NEXTRON®
burners is definitely a good replacement of the traditional
bulky sound proofing box.
Maintenance
Simple and time saving
The maintenance of the NEXTRON® burner can be easily
carried out thanks to a large opening of the above left side
of its housing that offers an easy access to the whole
combustion components.
Thanks to the RTC System, the combustion components
find again exactly the original position after the maintenance
operations. Year after year, the RTC System grants high quality
and reliable combustion on the NEXTRON® range.

Electronic control
Integrated and versatile
The option "load controller" is in the form of a regulator mounted on the door of the switch cabinet and connected
directly to the control box.
With the help of three integrated modules in their cabinet, the NEXTRON 6 to 9 are able to:
• adjust the fan speed to the required flame power;
• monitor the combustion quality by analyzing the concentration of O2 and CO in the flue gas;
• communicate remotely via an Ethernet network, as Modbus, Profibus or Ethernet.
