Product Specification

Brand Name : Ousikai Type : -
Place of Origin : Zhejiang, China (Mainland) Type : Pressurized Application : Water Heater Pipe Material : Glass color : blue, purple gold Pipe Material : Glass, High borosilicate glass 3.3

Product Description

We use four seasons constant  temperature coating technology, To minimize  the color difference.

Ousikai vacuum tube has 15years long life span ,and the vacuum tubes can work individually,so if the only one of them can't work,it won't influence on the others.The spare parts can be changed freely .it is suitable for the many residentbuildings.

Solar vacuum tube working principle:

1,The high quality vacuum tubes ansorb the solar ultraviolet ray;then heat the
cold water in the vacuum tube
2,The hot water rise in the top of the water tank ,and the cold water sink to
bottom,then heat by solar collector.so the whole system is always circulating
continuously.
3,The electromagnetism or ball valve can perform the water supply automatically,the
water in the tank is not sufficient ,the electromagnetism valve will open its valve,
the tap water flow in the tank ,if the water is full,it will close the valve automatically


Solar vacuum tube features:

1. High heat effectiveness: higher than all glass evacuated solar collector tube by 15%
2. heat pipes conduction: successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand
3. Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season
4. Low thermal capacity makes the tube start up quickly
5. Energy output within only 2 minutes of sunshine
6. Insulation temperature can reach 250deg;C, average heat efficiency can still be more than 50%; even under -50deg;C
