Technical characteristics:1.Welding: impulse welding ,arc argon welding2.Pressure tests: to ensure that the water tank is well.3.Second fold technology : to prevent the seal ring from being cut.4.Supporting stand:completely designed and patented.5.Foaming technology : complete appliance, integrated foaming , high efficiency, high rate of obdurate.6.R&D ability to design,updated technology products faster.Producing procedure:The exact technology ,complete mechanization, modularization and mass production, which are in strict conformity with the ISO9001 International Quality System,ensure the quality of products. The product line has over 50 procedures in all, every of which stipulates strict requirement of sizes, elements of performance, working procedure, inspection standard and so on. The brand-new mechanization and automatic product line created by JISHEN are bound to meet coming of new energy innovation.Water tank:1.SUS 304-2B stainless steelinner tank2.Polyurethane foam insulation3.Stainless or aluminum support 4.Trivalent element evacuated tube5.Electromagnetism or ball valve(optional)6.Electrical boost heater (optional)Working principle:1.The high quality vacuum tubes absorb the solar ultraviolet ray, then heat the cold water in the vacuum tube.2.The hot water rise in the top of the water tank, and the cold water sink to the bottom then heat by solar collector .So the whole system is always circulating continuously.3.The electromagnetism or ball valve can perform if the water supply automatically, the water in the tank is not sufficient, theelectromagnetism valve will open its valve, the tap water flow in the water tank, if the water is full, it will close the valve automatically.
