non-pressurized solar water heater

The specification of the solar water heater: (1)Inner tank: Food grade SUS304-2B stainless steel with optional 0.31mm, 0.37mm, 0.41mmthickness. It is formed once time, no welded joint. The service time is more longer and the water qualityis more cleaner. (2)Outer tank: Pearl- acrylic coating or aluminum alloy, strong and anticorrosion effectively. (3)Vacuum tube: 3.3 high borosilicate glass, 47mmx1.6mx16pc-30pc, 58mmx1.8mx16pc-30pc,resisting 25mm hail. (4)Heat insulating layer: Improved polyurethane integral foaming with 50-65mm thickness. (5)Bracket:Galvanized steel with 1.50mm thick or aluminum alloy with 1.7mm thick. (6)Fasteners:Stainless steel screws. (7)Seal:Imported silicone rubber polymer. (8)Temperature:45-95 degree centigrade, temperature is over than 50 degree in the winter (9)Hail resistance:25m Advantage of the solar water heater: (1)The vacuum tube coatingis stability. Vacuum tube can resist high temperature, the lifetime is up to 15 years. (2)Heat insulating layer keep theheat effectively, theheat preservation time is72hours. (3)Meeting the requirement ofbathing, washing, etc. (4)We can supply many kinds of products, meeting the different demand of the customers. (5)Make life more better is our occupation.
