Solar Vacuum And Glass Tube

We adopted advanced Nanometer Technology. Solar Vacuum And Glass Tube
Nanometer molecular engineering is applied to greatly improve the absorption function, the heat collecting ability increase 18%, the water temperature is higher, the same sunshine makes different hot water effciency, Adopt American technology and control stritly all the working procedure from cleaning to exhausting, so that the vacuum degree of interlayer in the tube can be 10-3Pa and radiation heat loss can be little. The unique carbonic coating is more reliable than the traditional AL-N/AL coating, and its ageing persistence is better, the coating property is longer, Vacuum tube is made of 3.3 high boron silicon glass and has small thermal expansion rate and high intesity, It can resist impact of hailstone under 25mm. These Solar Vacuum And Glass Tubes are available at industrial leading price.
