vCORAL VITRO, heating coils VITRIFIED STEEL tank water heaters with coils as the heat exchange system for the production of domestic hot water. Ideal for great heating power and high sporadic consumption requirements, they also have added advantages such as: • Over-dimensioned exchangers on exchange surface to provide the maximum domestic hot water production capacity with specific, high flows. • Optimum design of coils to achieve best system performance and the greatest heat exchange efficiency. • Elimination of cold zones in the storage tank to prevent the risk of bacterial proliferation (e.g. legionella bacteria). • Models with one exchange coil as the main heating source or with two exchange coils for combined systems, for example, solar panels (main source) and boiler (backup source). • Apt for incorporating an electric heating element • With two inspection and cleaning ports (top and side). • Maximum storage capacity thanks to the over-dimensioned PU thermal insulation, with a design that allows up to 1,000-litre capacity models to fit through 800 mm wide doors; facilitating their installation in places with limited access. • Cathodic protection installed with magnesium anode and anode load measurer on front panel.
