Medium output burners used in heating systems must meet five essential requirements: - simple implementation, - easy operation, - reliable and efficient settings, - rational use of energy, - low pollution emissions. The C.75 – C.100 burners are equipped with the innovative MDE ® system, which allows technicians to query the burner at any time and obtain operating information and details of startup phases. Burners with separate compartments combine our experience in designing domestic appliances with our skills in producing "medium output" equipment. A comprehensive control panel on the front of the burner contains the pressure regulator and the MDE ® system display. We recommend that these burners be used with the Variatron ® system. The burners function using modulating delivery air with natural gas and propane. They are designed to be installed on all types of boiler used in residential, tertiary and industrial buildings. Burners are designed, developed and built in compliance with the European standards EN 676. CUENOD burners bear the mark and meet the requirements of European Directives. 73/23/EEC = Low Voltage 89/336/EEC = Electromagnetic compatibility 89/392/EEC = Machinery 90/396/EEC = Gas appliances 92/42/EEC = Efficiency requirements for new mark hot water boilers. CUENOD burners are made according to the quality assurance requirements of ISO 9001, certified by AFAQ.
Low NOx The RTC ® system. The combination of a functional housing design, advanced combustion head technology and Memorized Head Settings (RTC ® ) ensures: • Total access, • Quick and easy maintenance, • Complete disassembly of all combustion head components (short, medium and long) in a single action without having to remove the burner, • Memorization of all optimised startup combustion settings during maintenance procedures. The AGP ® system. Developed and perfected by CUENOD, the AGP ® system has already won over gas combustion specialists. The system is fitted onto all our medium and high output burners. With this technology, burners guarantee: • a completely stable air-gas mix, • a high and constant CO 2 rate at all burner output levels, • accurate control of excess air, essentially for the optimum running of condensation generators. The AGP ® system also automatically corrects the following: • positive and negative gas pressure variations, • changes in air pressure due to electrical circuit voltage fluctuations and atmospheric pressure changes, • output according to pressure variations in the combustion chamber, especially during ignition. Low NOx combustion head. • The patented head design uses a combustion air pre-rotation system that increases air speed, homogenises the mix and reduces the time combustion products are in the flame, thus reducing thermal nitric oxide formation. • The use of natural gas reduces the amount of NOx produced to values of up to 80mg/kWh - in compliance with class 3 requirements of EN 676 - for the majority of standard-sized boilers (contact us for details).
