Specifications

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 effciency, Adopt American technology and control stritly all the working procedure from cleaning to exhausting ,so that the vacuum degree of interlayer in the tube can be 10-3Pa and radiation heat loss can be little.The unique carbonic coating is more reliable than the traditional AL-N/AL coating, and its ageing persistence is better, the coating property is longer,Vacuum tube is made of 3.3 high boron silicon glass and has small thermal expansion rate and high intesity ,It can resist impact of hailstone under 25mm.
Advanced technology:
Multi-layer magnetron sputtering gradation aluminum-nitrogen/aluminum sum 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/T2346-99(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 absorptance≧0.93,heat emissivity≦6%,less heat loss and good heat preservation,
Good Thermal Efficiency:
Hail Resistance: ≦Ф25mm
Working Pressure:0.6Mpa
Working Life≧15 years
