Product Description

* Features of construction
1. Water tanks are made by machine. Flower design pressed on aluminum alloy (or stainless steel) shell, beautiful and durable. Inner water tank is made of super SUS304 food grade stainless steel plates, welded by argon arc. Water is pure and drinkable.
2. Warm keeper of water tanks adopts polyurethane's cellular, thickness is 55mm.
3. Aluminum alloy (or stainless steel) supports are connected by bolts and nuts, firm and stable, easy to install.
4. Between vacuum tubes and inner water tank, we adopt milk white silicon glue rings to connect and seal them.
5. The tubes and supports are adjustable, power bearing is average, and can assure the vacuum tubes to use long time.

* Performance Data Vacuum Tubes
1. Whole glass vacuum tubes adopt super hard borax and silica glass;
2. Absorb rate: 93%, thermal radiation rate: 6 %( 100)
3. Temperature when exposed to sun without water: 250C, 2.5hours to boiling if using single tube;
4. Resist 25mm hail, using life can last 15 years.
