Солнечный водонагреватель Предварительно с подогревом

Model:Pre-heated sola water heater Cheap price 15years life Europen standard CE ISO SGS certificate Working Principle:Heat exchanger inside the tank which provides more than 1.5m2 of heat transfer area. When water flows through the coil, it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. Specifications: 1. Tank material: Interior SUS 304-2B 2. Outer: Color steel/ Zinc-aluminum coated steel 3. Frame: Aluminum alloy/Galvanized steel/Stainless steel 4. Heat exchanger: Red copper/Stainless steel 5. Pressure: 6 Bar 6. Heat preservation:72-80hrs 7. Hail resistance: 25mm Advantages: 1.It can withstand pressure of tap water when it works 2.Drinking water quality to promote life quality 3.Temperature preservation can last for 80 hours 4.Without volatile tubes 5.Without incrusting, long usage life Copper Coil Heat Exchanger Specifications Material 12mm x1.0mm copper pipe Surface Area 1.13m2 for 30 tube water heater Testing Pressure 9 bar Net Weight 15kg for 30 tube water heater Item Specification innertank SUS304-2B0.6mmthickness outertank 0.5mmGalvanizedsheet/stainlesssteel Glasstubedimension 58*1800mm volume 170L Insulationmaterial 50-65mm polyurethaneinsulation Framematerial AluminumAlloy/StainlessSteel Heatpipe anti-freezing>-35 Dailyefficiency ≥55%(≥42%inwinter) Heatpreservation 72h-80h Pressure 0.03Mpa Electricheater 1.5Kw-3Kw
