zuiwengting colour steel compact solar water heati

The principle:The series solar water heating systememploy the natural convection phenomenon called "thermosyphon", which results in hot water being lighter than cold water.The water heated in the tubes rises through the solar collector to enter the storage tank, while the cold water at the bottom of the tank flows into the tubes creating continuous circulation.The continue as along as the sun is heating the collector.Features:It is a solar domestic water system comprising all-glass evacuated tubular collector with water-in-glass manifold.It is non-pressuried system.It has airvent connected to the air in the tank. the pressure is less than 1 Mpa.1.Outer tank:0.4mm thickness Colour steel, Galvanized steel or Stainless steel304 2.Insulating layer :60mm 70mm Polyurethane Foam layer3.Inner tank :0.5mm thickness SUS304/2B food grade stainless steel4.Tube:Ø47mm*1500mm/ Ø58mm*1800mm All-glass Vacuumtube, High Borosilicate 3.3hardness glass 5.Stand frame:1.5mm thickness colour steel, Galvanized steel or stainless steel6.Reflector:Aluminum component, Al 99.85% surface oxidation7.Silicon seal:High quality silicagel sealTechnical Information of Solar water heater:TypeVacuum tubeTankArea(m2)Grosswet(kg)Loading Qtysizeqty(pcs)working temperaturediameter(mm)volume(liters)20G/40G/40HZW-500-1816ø58*180016-20°C 250°C5001603594292107ZW-500-1818ø58*180018-20°C 250°C5001803.465418091ZW-500-1820ø58*180020-20°C 250°C5002003.771337183ZW-500-1824ø58*180024-20°C 250°C5002404.579306476ZW-470-1816ø58*180016-20°C 250°C4701503664494109ZW-470-1818ø58*180018-20°C 250°C4701703.488428192ZW-470-1820ø58*180020-20°C 250°C4701903.769347284ZW-470-1824ø58*180024-20°C 250°C4702204.575326678
