Technical Data
Boiler body made entirely from steel, completely lined with a layer of high density rock wool, in turn covered by a stainless steel plate.
• Design pressure 6 bars, higher pressures on request.
• Pressurised combustion chamber, completely cooled and protected by a system ensuring uniform division of the cold system return water, to avoid dangerous temperature differences. The burner is not aligned with the combustion chamber but rather has been moved downwards. This assists flame reversal, reduces the flue gas pressure drop and consequently extends the hot water generator’s range of application.
• Tube bundle placed above the furnace so as to guarantee the flue gas passes through a hot section of the hot water generator and consequently reduce the possibility of condensate forming.
• Turbulators featuring a new design able to increase heat exchange, without affecting pressure drop in the boiler.
• Front door with reversible opening (right and left) and innovative closing system with micrometric adjustment on the hot water generator front plate.
• Flanged PN16 central heating flow outlet and return inlet connections.
• Supplied in two parts, steel body complete with casing, and satellite controls (satellite to be ordered separately).
