Thermoaccumulators constructed of duplex stainless steel, highly resistant to sting corrosion. All weldings are carried out by "top to top" T.I.G. process, thus eliminating any possibility of interstitial corrosion. All welds are subsequently shaded and passivated.
All thermoaccumulators include a supporting electrical resistance with external regulation thermostat and thermometer for viewing the water temperature inside the water heater.
Available with two interlaced internal exchangers to optimize the combination of two energy sources and capacities from 150 to 500 Liters.
NOTE: Security Group not included.
MAIN FEATURES
• Tub in duplex stainless steel sheet and exchangers in AISI 316L;
• Thermal insulation in rigid polyurethane foam injected at high density (>35kg/m3) with thermal conductivity from 0.022W/m.ºC to 50ºC;
• Electrostatically painted galvanized steel outer coating.
