tube solar water heater

Working principle: Itrelies on the natural circulation of water between the collector and the tank. As water is heated, it rises naturally up into the water tank, while cooler water in the water tank flows down to the bottom of the vacuum tubes, .As this circulation works throughout the whole system constantly Necessary partsa.water tank:Inner tankSUS304 2B food grade stainless steel 0.31mm-0.41mm;Outer tankSUS 304 BA Stainless steel or a grade color steel 0.31mm-0.41mm;Heat Preservation layerimported PU 50-60mm;Working Maximum pressure0.2Mpa;Capacity100L,130L, 150L, 200L , 250L,300Lb. vacuum tube Solar CollectorIt absorbs solar energy and converts it into heat then transfers the heat to the water in the tank.It consists of all-glass high borosilicate 3.3 co-axial double tube. The inner tube is coated with a sputtered solar selective coating Al-N/Al(blue) or Al-N/AL/SS/CU(red), And the outer tube is transparent allowing light rays to pass through with minimal reflection. c.frame:The system can be perfectly integrated with architecture. It can be installed on both flat roof and slope roof.Stainless Steel thickness 1.2mm-1.5mm Galvanized Steel platethickness 1.2mm-1.5mm Optional partsa.System controller: The controller can be used to show water temperature, level and control cold water supply or electric element work at setting time.b.Water auto filling tank(assistant tank)It is used to supply the cold water automatically. When the water tank reduces to a certain level, the assistant tank will supply the cold water automatically untill the water tank is full. Besides, it is more beautiful to match up with a suitable size water tank. Capacity 5L, 8L, 12L.c.Electrical heater:when without sunshine ,etc: in rain days and winter days, use for heating water.d.Magnesium bar:the anode bar to prevent furringThe parameter of whole system: Model Absorb area (m²) Water tank capacity (L) 20GP/40GP loading qty (sets) ITM-47/1500-1000.9310060/116ITM-47/1500-1101.0411056/108ITM-47/1500-1301.2413047/91ITM-47/1500-1651.5516537/85ITM-58/1800-1501.6215037/71ITM-58/1800-2001.94420032/61ITM-58/1800-2502.4325025/48ITM-58/1800-3005.1230018/37The system can endure the maximum pressure up to 0.2 Mpa.You 're welcomed to contact me for more information.Eric Zhu Tel:0086 573 87788246
