Product Description Product DescriptionIn evacuated tubes, there is copper pipe folded into a U-shape with aluminum thermal conductors to transfer the solar energy from the inside wall of the evacuated tubes to the circulation fluid in it. Then the circulation fluid take the heat energy into collectors manifold.Product ParametersProduct ModelSLU4718-24-L/SStructureMaterialParameterFlow PipeHeader PipeCooper TP2 φ22×0.6 mmHeader PipeCooper TP2 φ8×0.5mmHeader Pipe Quantity24Hole Distance72 mmJoint MaterialBrassConnector SizeG3/4HeaderOverall size( Width* Height*Thickness)1560*1912*163(mm)Header MaterialHigh grade Aluminum Alloy 6063- T5SurfacePainting GrayFrame MaterialHigh grade Aluminum Alloy 6063- T5/ SS304Frame SurfaceOxidationFrame SettlingSS304/SS316 Bolts/Nuts/WashersSolar Vacuum TubeSolar Vacuum Tube MaterialBorosilicate Glass Tube 3.3Solar Vacuum Tube SizeΦ47×1800(mm)Collector SealingSilicone rubberFix of Solar Vacuum TubeNylonInsulationInsulation MaterialAluminum silicate/polyurethaneInstallationRecommend Installation Distance≥3.5mPerformanceRated Work Pressure0.6MPaTest Pressure0.9MpaGross Area2.49m2 Aperture Area1.95m2 Heat PerformanceIn accordance with GB/T17581- 2007 Company ProfileSince its establishment in 2002, Shandong Longguang Tianxu Solar Energy Co., Ltd (hereinafter referred to as "Tianxu") has always engaged itself in the R&D, production, sales and service of high borosilicate glass tubes and new energy products including solar water heaters, solar vacuum tubes, solar heat collecting project, air source heat pump, photovoltaic products, etc. Tianxu has 10 sets of electric furnaces, 70 sets of solar vacuum tube production line and 3 sets of solar water heater production lines. The annual output has reached one million tons of high borosilicate glass, over 16 million solar vacuum tubes makes Tianxu the largest manufacturing base of high borosilicate glass tubes and solar vacuum tubes. In 2015, Tianxu established a joint venture company with Beijing Tsinghua Solar Co., Ltd- the solar vacuum tube technology initiator in the world. The newly established company has the world's most advanced solar vacuum tube production lines. Our Advantages1.Evacuated tubes with triple layer selective absorber coating, vacuum degree≥5.2x10-4Pa, absorbing efficiency≥92.5%;2.Applied advanced leaking test technology to ensure the whole system working stably and reliably;3.With effective heat energy transferring Aluminum fins, U pipe collectors get higher temperature in short time;4.High and constant pressure polyurethane foaming technology ensure the outstanding insulation quality;5.Optimal and innovative design make collectors integrated into different buildings;6.Circulation fluid in closed copper pipes(U Pipe), no water in vacuum tubes. There is no corrosion, no leaking , no scaling, no occasional tube breakages in collectors;7.Working life ≥20 years.Packaging & ShippingCertifications
