Non-pressurized solar collector (Vertical type)

Description

Non-pressurized solar collector Working Principle: 1, The solar collector connect with non-pressurized solar tank 2, The water pass through solar manifold then into vaccum tube, vacuum tube absorb solar energy, heating the water inside of vacuum tube 3, According to density difference, the cold water through down into vacuum tube, and hot water flow up into solar manifold, then storage in heat protection water tank 4, After circulation by temperature circulation pump, all of the cold water will be heated to hot water and storaged in heat protection water tank. Features: 1, The solar collector is more suitable for solar hot water project, because you can free compose many solar collectors for connect with different capacity solar tank, for example, the capacity can do ***0liters, ***0liters, ***0liters, **********0liters**********0liters and more , normally use in hotel, swimming pool, and others large project 2, The solar collector is separated with non-pressurized solar tank, so it need temperature circulation pump for promote circulation, when the water temperature is difference between storage tank and solar collector, the pump will strat working, cold water will into vacuum tube for heating, and hot water will back to solar tank for storage. 3, The solar collector and solar tank is non-pressurized , so exhaust vent on solar collector and exhaust pipe on solar tank is most important for protection the solar hot water system The solar collector’s material: a)Solar manifold : Octagonal type solar manifold, Vertical type solar collector Internal: SUS****2B Outer shell: Color armor plate b)Frame: Galvanized steel with powder coating c)Insulation layer: polyurethane foam d)Vacuum tube: high borosilicate glass with AL/N/AL coating, Cu/SS/ALN coating for optional e) Specification of vacuum tube: φ*7mm/***0mm or φ*8mm/***0mm vacuum tube f)Quantity of tubes: from *0tubes to *2tubes for optional
