Detailed Product Description
Advantage 1. Its surface with selective coating to ensure perfect heat absorptance so that water can be heated. And the outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 25mm in diameter 2. High efficient temperature raised: adopting the advanced coating technology, light converted into heat is 10%higher than normal vacuum tube. 3. Endure the coldest temperature: adopting the advanced vacuum technology, the vacuum degree can amount 5x10¡¥$Pa convection heat emission, at the same time the infrared reflector layer reduces the radiant emission, enable the tubes can work well, in coldest temperature area. 4.Function stable: it has long longevity; going through 36 procedures ensure the coating stabilization
