Low Pressure Solar Heater

Basic Info.Model NO.ITM-NP seriesCollector ComponentsGlass Vacuum TubeTrademarkintermaSpecificationGB19141-2003OriginHaining City, ChinaHS Code8419191000Product Description Gravity Solar Water HeaterWorking principle:Gravity Solar Water Heater relies on the natural gravity circulation of water between the collector and the tank. After water in the vacuum tubes 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, we get the hot water.I. Water tankIt works as the heat reserve tank, which require high quality of inner tank and preservation material;Inner tank: SUS304 2B food grade stainless steel 0.4~0.5mm;Outer tank: SUS 304 BA Stainless steel or A Grade color steel 0.31mm-0.41mm;Heat Preservation layer: Imported PU 50-60mm;Working Maximum pressure: 0.2Mpa;Capacity: 85L to 300LII. VacuumTube Solar Collector:Evacuated tubes are the absorber of the solar water heater, which absorb solar energy and convert it into heat then transfer the heat into water for use in water heating. It is the most improtant part of the solar water heater.It consists of all-glass high borosilicate 3.3 co-axial double tube, glass. The inner tube is coated with a sputtered solar selective coating (Al-N/Al) or (Al-N/AL/SS/CU), this coated inner tube is closed at one end and sealed at the other end to the outer tube.The annular space between the outer tube and inner tube is evacuated to virtualy eliminate heat loss by conduction and convection. And the outer tube is transparent allowing light rays to pass through with minimal reflection. This "evacuation" of the gasses forms a vacuum, which is an important factor in the performance of the evacuated tubes.III. FrameThe angel of bracket is decided according to your latitude. Its performance is stable, reliable and easy installation. It adopts scientific structure to reach the best performance. The system can be perfectly integrated with architecture. It can be installed on both flat roof and slope roof.Stainless Steel thickness 1.2mm-1.5mmGalvanized Steel plate with plastic sprayingThe Optional parts of the whole system:I. System controllerThe controller can be used to show water temperature, level and control cold water supply or electric element work at setting time.II. Water auto filling tank(assistant tank)The assistant tank 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, 12LIII. Electrical heaterWhen without sunshine, etc: In rain days and winter days, use for heating water.IIII. Magnesium barThe anode bar to prevent furringAdaptation: Resorts, country houses, private homes, agriculture, construction siteLearn more about products detailed description, pricing and service, Please send mail to us.         Model Capacity Diameter& Length of tube(mm) Qty. of solar tubes Serve people Loading of 20GP/40GP/40HQ ITM-NP-30 300L 58*1800 30pcs 6 to 7 26/54/63 ITM-NP-25 250L 58*1800 25pcs 5 to 6 30/64/75 ITM-NP-20 200L 58*1800 20pcs 4 to 5 36/76/90 ITM-NP-15 150L 58*1800 15pcs 3 to 4 47/99/116 ITM-NP-10 100L 58*1800 10pcs 2 to 3 62/132/155
