Nautic Boilers Quick B3 Project. Built for nautical use, they work with electrical resistance 220 V for use in the quay or with generator and, with an exclusive winding up- type heat exchanger with the heat released by the cooling circuit of the engine. The Nautic Boiler" keep the water drinkable and are equipped with anode against the effects of electrolysis. The heat exchanger of the " Nautic Boiler B3" Quick is in AISI 316L stainless steel and develops a remarkable capacity of heat exchange, bigger than that of the other nautical boilers that are currently available on the market. The tank has a thickness of 1,5 mm, in AISI 316 stainless steel and welded in a protective atmosphere of Argon gas, thus particularly resistant to the corrosive agents and the electrical resistance is in Incoloy? stainless steel. The thermal insulation is provided by an injection foaming of polyurethane of high density with closed cells, thus by providing a better and longer thermal retention. 3- year warranty.
