Product Description

Solar Water Heater Evacuated Vacuum Tube
CE, ISO********8, CE,CCC SOLAR KEYMARK certificate
Over *0years life time
OEM, ODM
Made-in-China

The heat collecting ability increase *8%, the water temperature is higher; The same sunshine makes different hot water efficiency. The unique carbonic coating(Cu-Ss-Al/N/Al) is more reliable than the traditional AL-N/AL coating, and its ageing persistence is better, the coating property is longer.

Advanced technology:
Multi-layer magnetron sputtering gradation aluminum-nitrogen/ aluminum sun selective absorption coating improve the heat collecting efficiency of high vacuum tube.

Well material:
Vacuum tube is made of 3.3 high boron silicon glass tube that satisfies QB/T******9(idt)ISO********8 standard, with high transmittance, well cold and thermal shock resistance and strong optics stability.

Quality Assurance:
Strictly follows the national standards GB/T*********7 starting from raw material purchase to finished products, all the employees cooperate well and never allow any faulty products.
