    Energy Saving Three Target Solar Vacuum Tube

INTRODUCTIONS                                                                                      

Three target solar vacuum tube consists of the inner and outer tubes, which are cut and coated on the condition of high temperature. The inner tube is coated in the three target magnetron sputtering plating equipments which is the newest three target technology and intorduced from German. Using the coating material of argon and nitrogen aims at becoming three membranes Cu-SS-ALN. It takes about 60 minutes. Then, melting the inner and outer tube together and evacuating empty in the vacuum machine. Evacuated tube is core of the solar water heater.  Its performance lies on the coating technology, The three-target evacuated tube rises the heat more than 12%.

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.
