Solar Keymark certification
All-glass Evacuated solar collector tube

 Solar tuber features: 

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.

Common specification: 47×1500mm ; 58×1800mm;
