Product Description
As one of professional manufactures of solar vacuum tube , we are offering all specification of solar vacuum, such as 47*1500mm, 47*1800mm, 58*1800mm, and so on.
Right now, we can offer 10 million pieces per year and have exported tubes to more than 20 countries around the world, such as India, Turkey, Mexico, Syria, Lithuania, Brazil, Chile, USA, Jordan, Egypt and so on
We always provide high quality solar vacuum tube, with high quality borosilicate glass 3.3, gradual change of CU-SS-ALN/ALN selective absorption coating,fooliwng pictures is our test of mechanical shock resistance.
