2 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. 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 lower than 81 db(a) up to 1 MW. This integrated and patented system on all NEXTRON burners is definitely a good replacement of the traditional bulky sound proofing box. 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. 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.

3 Communication User-friendly and universal Elcogram: a universal language. 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. 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. 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.

4 Combustion control main features Visualization and Remote Monitoring O 2 /CO Control Bus Interface BT 3 Variatron LEM/LCM 1 PID VSM 1 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 O 2 and CO in the flue gas; communicate remotely via an Ethernet network, as Modbus, Profibus or Ethernet.
