Feature:
Nanometer Technology Solar Vacuum Tube
Nanometer molecular engineering is applied to greatly improve the absorption function, the heat collecting ability increase 18%, the water temperature is higher; the same sunshine makes different hot water efficiency.
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/T2436-99(idt)ISO4803-1978 standard, with high transmittance, well cold and thermal shock resistance and strong optics stability.
Quality Assurance
Strictly follows the national standards GB/T17049-1997 starting from raw material purchase to finished products, all the employees cooperate well and never allow any faulty products.
Performance parameter of the vacuum tube
High collecting efficiency: magnetron sputtering gradation aluminum-nitrogen/ aluminum sun selective absorption coating, solar absorptance0.93, heat emissivity6%, less heat loss and good heat preservation.
