PRODUCT STRUCTURE

WORKING PRINCIPLE

High Efficiency Solar Vacuum Tube consists of the inner and outer tubes, which are cut and coated on the condition of high temperature.

Solar Vacuum Tubes are the absorber of the solar water heater.

They absorb solar energy converting it into heat energy for use in water heating.

The hot water rise to water tank and the cool water fall to the bottom of the vacuum tube.

As the gravity theory, the hot water and cool water are continuously circulation in the vacuum tube and water tank.

ADVANTAGES

1. Excellent performance of absorbing, but low heat loss, Especially adapted to sever cold regions,(super heat preservation). With the help of DC magnetron sputtering technology, the absorptance of 0.94 - 0.96 and emittance of 0.04 - 0.06 has been achieved.

2. Excellent resistance of burst. Improved molecule structure of plated selective coating makes the highest of vacuum tube working temperature as high as 300 centigrade degree, effectively preventing the coating from bursting, aging, discoloring, function attenuating because of long time burn under the sun, prolonging its life span to 15 years.

3. Excellent resistance of corrosion, long life span ( up to 15 years) Standard

4. Reducing the fouling on the tube wall, keeping water clean.

5. The efficiency of a vacuum tube solar hot water heater is dependent upon a number of factors, one important one being the level of evacuated radiation (insolation) in your region.
