1 QUADRIFOGLIO B STAINLESS STEEL CONDENSING GENERATOR > PRODUCT PLUSES: - Steel vertical module with low thermal load, huge water content - The exchanger in stainless steel AISI 31 Ti consists in a tubes bundle. The helical rolling section is patented and has been designed to enhance thermal exchange and fumes condensation. - Premixed microflame burner, Low NOx combustion, vertical layout The reduced vertical clearance enables water/flue gas exchange throughout the entire surface of the exchanger. Quick opening system of combustion chamber door (right/left reversible) for inspection and maintenance operations. - Control board with button for regulation and setting of parameters, wide interface display and ON/ OFF switch - Pocket on boiler flow, for the eventual installation of a safety valve - Equipped with temperature probes on flow and return and water minimum pressure switch - Flue gas outlet reversible on right or left side of the generator - Flue gas no-return system for modular installation. As a standard on each boiler. - Wide and complete offer of water, gas and flues accessories - necessary for the installation of cascades including 2 or 3 generators > PRODUCT ADVANTAGES: - Very high efficiency: can exceed 109 in some operating conditions - Wide output range of Quadrifoglio s offer: from 70 to 90 (cascade of 3 modules of 320 each) - The huge water volume inside the generator enables connection to the heating system without adding separation devices, permitting design of systems with a very high ΔT - Double system return, thus managing systems operating with different temperature, albeit granting the best possible layering inside the boiler body - Smallest polluting emissions (class 5 NOx) - Combustion control through microprocessor, reaching then modulation of the single generator until 20 of the maximum capacity - Quadrifoglio electronics handles modular installations, domestic hot water production via a storage tank and system pump with outside temperature compensation on flow water temperature PROTECTED REMOTE MODULAR CLASS 5 CLIMATIC RANGE RATED NOX MODEL Heat thermal input 5,5 11,0 207,0 299,0 14,0 23,0 41,0 2,0 Heat output (80 C/0 C) Heat output (50 C/30 C) Efficiency (80 C/0 C) Efficiency (50 C/30 C) P P P P Efficiency 30 reduced load 109, 109, 109, 109, Energy marking (92/42 EEC) NOx emission class Water content liters Operating pressure bar bar Empty weight Kg Protection rating IP X0D X0D X0D X0D CODE 0RB010WA 0RB110WA 0RB410WA 0RB10WA 4,4 13,7 9,9 15,0 98,3 114,0 22,5 125,0 24,8 98,3 204,0 40,2 220,0 44,2 98,5 294,5 320,0,8 98,5 Gennaio 2014
