Yaoguo Solar *7 ***0mm solar vacuum tubes for solar
collectors
Solar
vacuum tube is the core component of solar water
heater and solar hot water project and heating engineering. Its
performance determines the quality of solar heat utilization.
Yaoguo Solar Thermal company introduced domestic advanced automated
connecting tail machine, automatic eyelet machine, automatic
washing machine, automatic drying machine and the latest magnetron
sputtering technology production line designed by Tsinghua
University, to ensure the quality of coating, and make the thermal
efficiency improved by more than *2%.Through strict control of
vacuum technology, we can ensure the high heat efficiency and
anti-attenuation performance of the solar evacuated tubes. Because
of the advanced equipments and strict management, various types of
vacuum tubes produced by Yaoguo have the characteristics of high
temperature resistance, cold resistance, fast heating and so
on.
