80L-360L Non-Pressurized Vacuum Tube Solar Water Heater with CE Certification

Features description:Non-pressurized solar water heater is such kind of a most economical system with high efficiency at the same time. It works depending on the gravity of water, so it's much better to be installed on the slope or flat roof as top as possible to get enough hydraulic pressure. A simple assistant tank can be equipped for tap water refill automatically or with an intelligent controller to control the startup of auxiliary heating device at the same time.Vacuum tube: Hail-resisting borosilicate glass with high-tech selective coating ensures an efficient solar collecting, tri-target vacuum tube with its patent interference coating makes the efficiency not only improved by 12% but also with a high temperature resistantce (380oC).Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water clean and drinkable, together with advanced welding technics to ensure it with a long lifespan (15 years). Water tank shell: Imported color steel plate, with its outer coating treatment ensures a long life even to ocean coast weather.Insulation Layer: Germany-imported polyurethane integrated foam-forming with twice slaking treatment, preserves hot water constantly as long as 70~80 hours.Supporting Bracket: Hot-DIP galvanized steel plate with a good weight bearing and wind resistance(140 km/hr), super mechanical performance and corrosion resistance ensures a long life to ocean coast, easy installation, universal bracket suitable for either flat or slope roof installation.Accessories: Stainless bolts & nuts, water-proof silicon rubber, anti-aging dustproof rubber seal, plastic pipe holder and ventilating cap to ensure their lives as long as other parts of the systemOptional DevicesAssistant tank, to automatically feed tap water into storage tank to keep it sufficient alwaysElectrical heater, as an auxiliary heating element in case of raining or snowing days so as to ensure a continous hot water supplyIntelligent controller, automatically controls water refill and startup of auxiliary heating device, more intelligent operationBooster Pump, a choice for those area without tap water or with a unstable water supplyWarranty: 3 years international responsibility for integrated system and 15 years for glass vacuum tubes due to original quality problems   ModelILNA-5818G460CWater tankInner tank material Food grade SUS304-2B stainless steelInner tank thickness 0.41mmInner tank DiameterΦ360mmInsulation material35KG/m³ high density polyurethaneInsulation thickness 50mmOuter tank materialColor painted steel Outer tank thickness 0.41mmOuter tank DiameterΦ460mmRated operating pressure0.05MpaTubeVacuum tube modelΦ58x1800 mm vacuum tube , 2KG/PCSNumber of vacuum tubes8, 10, 12, 15, 18, 20, 24, 30, 36, 42, 48, 50Hail resistantΦ 25mmBracketBracket materialColor painted steel Bracket thickness 1.2-1.5mmBracket angle25-50 degreeOptional accessoriesElectric heating, anode magnesium rod, intelligent controller, assistant tank, etc.CertificateCE, CCC, INMETRO, BEIDE, etc.
