Detailed Product Description

Solar vacuum tube

Adopt international advanced interferometer coating technique. Absorbing layer is coated with
Stainless Steel and Nitrided Aluminum. That effectively solved the problem such as performance
attenuation of normal vacuum tube under high temperature for a long time.

Reflection metal layer with super-pure copper mirror has high heat efficiency, low
reflectivity, resist low temperature and perform stably. The tube has better quality at the
same price than normal tube , is especially used for separate pressurized hot water system and
project. It can be applied for industrial and technical field such as generating electricity ,
refrigerating , desalting of seawater.

Select 3.3 high borosilicon glass tube in according with GB/T2436-99(ISO4803-1978) standard.
It has good performance of cold and heat resistance , high sunlight permeation, and strong
optics stability.

Produce and inspect according to enterprise standard higher than GB/17049-1997 national
standard.
