Solar Thermal Vacuum Tube
high temperature Three Target Evacuated Tube Solar Collector Vacuum Glass Tube from china glass tube manufacturer
Product Description: Glass evacuated tubes are the key component of the solar collectors. Each evacuated tube consists of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass, that is able to resist impact from hail up to 25mm in diameter. The inner tube is also made of borosilicate glass tube, but coated with a special selective coating which features excellent solar heat absorption and minimal heat reflection properties. The air is
