solar vacuum tube

high temperature,frost resistance,high heat-efficiency,long service life ,anti-scale,no rolling water in the tube,and so on

 All-glass solar vacuum tube solar collector tubes are the first high-tech product in China which is developed in our company, with independent intellectual property rights, and the patent number is ZL99.221421.1. It has won many tittles such as the “high-tech product in Shandong Province”, “Reliable supporting products in Chinese collector energy industry”.

    This product has many features such as high temperature, frost resistance, high heat-efficiency, long service life, anti-scale, no rolling water in the tube, and no influence of use when single tube is damaged.

     At the same time, after dedicated study of researchers, through the further optimization of thermal conductive working substance, and further improvement of the technology, now this product possesses following advantages such as fast start under low-temperature, high efficient heat conduction, no freeze and anti-frost in the tubes under minus 60°C environment in the cold area. The tube can withstand high temperature in the strong light of area. It is the optimal choice for home single water heater.
