Integrative Druck stehende Sonnenenergie Warmwasserbereiter

Integrative pressurized solar energy water heater working principle: 1) A copper coiler with 20-50 meters length is installed inside water storage tank as heat exchange.When water flows into copper coiler,it collects the heat from water in the bank,then it can bear much more higher pressure. 2) State water supply direct enter into the inlet water hole, go through the heat exchanger hot water come out from the out let water hole 3) The air vent hole can connected with central heat supply pipe to heat the tank water Product name:Integrative pressurized solar energy water heater Model: KUH58A-24 Features: 1) Vacuum tube size: 58 X 1800mm 2) Inner tank: Stainless steel 304 2B food grade 3) Outer tank: Aluminum gavanizedwith power painting,we can make different colors according to your demands. 4) Frame material: Aluminum gavanized with power painting.We can make the colors according to your demands. 5) Insulating: 50mm polyurethane total forming with pressure and best density 40kgs/m3 6) Available sizes: 15,18, 20, 22, 24, 28, 30, 36,42 tubes 7) Capacity of tank: 135 L to460 L 8) Red copper coil&high efficiency Technical data: StructureAll-glass concentric dual tube geometerGlass material Borosilicate glassOut tube diameter and thickness47 0.7mm & - 1.5mm58 0.7mm & - 2.0mm70 0.7mm & - 2.0mmInner tube diameter and thickness37 0.7mm & - 1.5mm47 0.7mm & - 1.6mmTube length1200( 5mm) 1500( 5mm)1700( 5mm)2000( 5mm)Absorbing coating propertiesConstructionGraded Al - N/Al solar selective absorbing coatingMethod to deposition DC reactive sputteringAbsorbance>91%Emittance<8%(80)VacuumP<5x10 PaStagnation parameter- 230/ KWSolar radiance exposure for obtaining a preset water temperature-2.8 MJ/Average heat loss coefficient-0.8 W/()Lifetime15 years
