The relation between vacuum tube and solar energy, which is just like that of engine and automobile. The performance of vacuum tube directly determines the thermal performance of the solar hot water heater. Only if the performance of vacuum tubes is above the base line that the solar energy can work well.

Heat collection efficiency must be high enough to ensure the customer can use hot water all the year round.

Film layer performance must be stable enough to ensure the life span is above ten years.

Bear the intensity and rigidity, which can withstand the atrocious weather outdoor and can last more than ten years.

Himin Solar Energy applies the international patented interference film coating “3 Hi” vacuum tube to ensure sufficient hot water in winter.
Compared with the traditional gradual variety coating film, the heat collection efficiency of the new film increases largely to ensure the big quantity as well as the high temperature of the hot water.
The coating film has a nice stability with nearly no attenuation in performance and can be used more than ten years.
Apply the “three target”technique and Germany Optosol on line fast?? measurement equipment to check vacuum tubes in every furnace and which can guarantee high absorption coefficient and low emission coefficient.

The exhausting time lasts for 90 minutes under high temperature of 430oC. the vacuum rate can achieve 5.0×10-4Pa, which is 100 times than that of national standard.
