Gāzes katls MODULEX EXT 770

MODULEX EXT System composed by a modulating, Low NOx, multi-burners, condensing boiler, for indoor / outdoor installation, IP X5D Output range: from 100 to 1200 kW • Maximum working pressure: 6 bar • For operation in deep sliding temperature, with natural gas or LPG. • Primary ring with hydraulic separator (optional) • Plate heat exchanger (optional), modulating pump, “Y” shaped filter (excepted the filtering cartridge), additional safety devices kit • Each aluminium /silicon/magnesium module has its own combustion chamber with a total radiation burner, modulating fan, gas valve, flame and ignition BMM control device, NTC sensor for local temperature control and safety thermostat • Total pre-mix modulating burners, with flame surface in metallic radiating mesh. The air– gas premixing occurs within the fan, with built-in check valve • Constituted from pre-assembled thermal modules without hydraulic interception in between. • Air suction system from the boiler room or directly from outside of the boiler room through ducts (optional) • For indoor / outdoor installation, made with totally water proof casing, IP X5D, in electro-galvanized steel plate and epoxy-polyester powder painted in grey colour • Possibility of cascade installation of 2 or more boilers (up to 8), by using an additional E8 controller as MASTER. • Logic of operation: repartition of the requested power on the larger number of modules, firing at the lowest possible rate (up to 12 kW for the models 100 to 350 or up to 22 kW for the models 440 to 900) in order to obtain the maximum efficiency • D.H.W. production through a priority sensor, that controls a dedicated loading pump or a 3-way diverting valve via the E8 • Supervision of boiler operation and temperatures status • Alarms management and parameters setting • Relay for the activation of a constant speed pump • E8 controller inserted in the foldaway facia panel
