2015 hot sales! 3.3 high borosilicate all-glass evacuated solar collector tubes

Our vacuum  collectors tube can start up fast and collects solar energy fully, there is no need to wait and the water isavailable immediately, high level vacuum ensure operation under cold weather, and the unique super copper surface allowing lower reflection and minimal heat loss, the current products mainly include: diameter: 47/58mm, and the length is 1800mm, but we calso provide products as your request. Long time warranty for 15 years.

3.3 high borosilicate glass tube performance and usage introduction

 High borosilicate glass has first -class  level of hydrolysis resistance performance high-borosilicate glass, widely used in laboratory and chemical plants, in recent years in the solar

 heating device on the application have developed rapidly.

Advantages

High borosilicate 3.3 glass product has known as chemical stability, high voltage, resistance to 

thermal shock and excellent processing performance characteristics.
