vacuum tube/high quality

1.High efficiency heat collecting, use copper for collecting; 2.Low emission; 3.High quality, warranty 15years

  pressurized solar collector

Vacuum tubes transfers sunlight into heat energy, and then into the heat transferring fluid by fins outside the heat pipes made of cooper. Finally the energy will be released at the end of the heat pipe inside the header, heat transferring fluid inside which will get the energy to heat water in the tank. Features:1. Pressure-bearing operation, no water flows in the vacuum tube, so water scale and tube exposition are avoided.

2. It can be integrated with the architecture perfectly and be connected with the existing pipes.

3. Interferential film coated vacuum tube with absorptance among 94% to 96%, with vacuum degree in 5×10-4 Mpa; the service life will be not less than 15 years.

4. Gain the Solar Keymark certificate and CE certificate, meet EN12975 standard.Technical parameters:1. Vacuum tube/ evacuated tube
