Capacity>100LStructure Compact Type Pressure Unpressurized Interior Material Copper Collector ComponentsGlass Vacuum TubeComposition Collector CertificationCE, ISO9001, CCCProduct DescriptionComponent of Production:Material of Inner Tank: SUS304-2B Stainless Steel, thickness: 0.4mm, 0.5mm, 0.6mmMaterial of Outer Tank:  Stainless steel/colorful steel, thickness: 0.4mmCopper Coil: diameter : 12mm, thickness: 1mmHeat Preservation : polyurethane foam with 55mm thicknessMagnetic-controlled Al-N-Al splash all glass evacuated heat-collecting tubesSpecification: Φ58mm*1800mmMaterial of Support: Stainless steel ,thickness: 1.2mm/1.5mmCapacity: 100L-300LFeatures:Pre-heated pressurized solar water heater is our newest products, adopt the copper coil , it improves the problem of traditional solar water heater, like the hot water is limited, few out water , heat for long time, the water quality is worse and worse. The technology we first research heat for twice; is successful, let the connection of the high temperature high effect and hot water fast circulation perfect, pushing the solar energy into a new stage.Technical Specifications:The water of the heat preservation water tank is just decalescence, heat accumulation and thermolysis the water of the water tank is invariableness. The vacuum tube collector absorb the heat energy to heat the water in heat storage tank, when using the hot water, the cold water flows through the inlet, the copper coil absorb the heat then transfer into the cold water ,so that the temperature rise up ceaseless, for the original features of the copper coil, the water temperature of the outlet is close to the water temperature of the water tank, so the high pressure of the cold water into the copper coil and absorb the temperature, at last the water can be used.    Pre-heated pressured solar collectors provides mains pressure pre-heating via a high efficiency copper coil heat exchanger located within the solar collector tank.The way in which the Mains Pressure solar collector heats water is the same as the Non pressure solar collector.Rather than using the water in the tank directly, as the Non pressure does, the type uses a 45~60 copper coil.Heat exchanger inside the tank which provides more than 1.2m2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. One advantage of this system is that almost no water is introduced into the tank (apart from occasional topping up),so corrosion and scale buildup are almost totally eliminated. Tanks are designed for low to medium pressure applications using gravity feed tank or pressure reduction valve. Direct connection to mains pressure water supply is not permitted. Please check your local building/plumbing regulations regarding the installation of water tanks.
