High Efficient CE Certified Color Steel Vacuum Panels Solar Water Heaters

Specifications

Vacuum Panels Solar Water Heaters Technical Parameters:

Vacuum Panels Solar Water Heaters  Features:

1) Inner and outside water tank shell all are made of SUS3042B food grade stainless steel plates, welded by argon arc. Water is pure and drinkable
2) Heat insulation of water tanks adopts polyurethane foam and the thickness is 55mm

3) Silicon rings to connect and seal them

4) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time

5) Whole glass vacuum tubes adopt super hard borax and silica glass

6) Absorption rate: =93%, thermal radiation rate: =6%

7) It resists 25mm hail and the using life can last 15 years

8) Temperature when exposed to sun without water: 250oC, 2.5 hours to boiling point if using single tube

9) If you use electrical appliances to aid heating and to switch off the power supple before bathing

10) Please test the water temperature before using, in order to avoid scalding

 

Vacuum tube: Hail-resisting 3.3 borosilicate glass with high-tech single-target selective coating ensures an efficient solar collecting, tri-target vacuum tube with its patent interference coating makes the efficiency not only improved by 12% but also with a 380^oC high temperature resistantce without peeling off the coating layer.

Inner water tank: Food-grade stainless steel SUS304-2B as inner tank keeps the water clean and drinkable, together with advanced argon arc welding technics to ensure it with a long lifespan (more than 15 years).

Water tank shell: Imported color steel plate, with its special coating treatment ensures a long life even to ocean coast weather.

Insulation Layer: High-density polyurethane integrated foam-forming with twice slaking treatment, preserves hot water temperature as long as 70~80 hours.

Supporting Bracket: Very strong hot-dip galvanized steel plate with a good weight bearing and wind resistance design (140 km/hr), painting or baking process ensures a super mechanical performance and corrosion resistance, easy installation, universal bracket suitable for either flat and slope roof installation.

Accessories: Stainless bolts & nuts, water-proof silicon rubber, anti-aging dustproof rubber seal, plastic pipe holder and ventilating cap to ensure their lives as long as other parts of the system

Optional Devices

Assistant tank,  automatically feed tap water into storage tank to keep it sufficient always

Electrical heater, as an auxiliary heating element in case of raining or cloudy days so as to ensure a continous hot water supply

Intelligent controller, automatically controls water refill and startup of auxiliary heating device, more intelligent system operation

Warranty: 3 years international responsibility for integrated system exchange and 15 years for glass vacuum tube compensation due to original quality problems
