Solarwarmwasserbereiter (drucklos)

Solar Water Heater (Non-pressurized) 1,vacuum tube length:47/1500mm,58/1800 2,vacuum tubes:15pcs,18pcs,20pcs,24pcs,30pcs 3,Outer tank material:202stainless steel with 0.31mm 4,Inner tank material:SUS304-2Bstainless steel thickness :0.41mm or 0.31mm 5,Insulation:foaming polyurethane thickness:50mm or 55mm 6,Optional electric heater:220v-240v 1500w/3000w 7,frame material :202 stainless steel 8,we could product for customer'special need It has 15years long life span ,and the vacuum tubes can work individually, so if the only one of them can't work,it won't influence on the others. The spare parts can be changed freely .it is suitable for the many resident buildings. Working principle: 1,The high quality vacuum tubes ansorb 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 bottom,then heat by solar collector.so the whole system is always circulating continuously. 3,The electromagnetism or ball valve can perform the water supply automatically,the water in the tank is not sufficient ,the electromagnetism valve will open its valve, the tap water flow in the tank ,if the water is full,it will close the valve automatically Separate Pressurized Solar Water Heater Water Tank: 1,Inner tank:SUS304-2B material,150L-200L1.2mm thickness,300L-400L1.5mm 2,Insulation:50mm polyurethan foam 3,Outer tank:0.5mm thickness galvanized steel material 4,P/T relief valve ,electrical heater element with terminator 5,Heat exchanger:20m long,12mm diameter,1mm thickness coppper pipe. Feature: 1,Pipeline is made of all red cooper and conducted by heat transfer medium liquid. 2,Water doesn''t flow in the vacuum tubes and is operated when confined. 3,The crust uses aluminum alloy mould material of high strength with airflow design. 4,It is furnished in good style . 5,Tank is equipped with electric water heater setting,automatic temperature controller. 6,With increased anode magnesium bar stick to prevent furring. 7,The insulating layer uses polyurethane bulk bubble. 8,It successfully carries out installation of separation according to fabricating yard.
