Thermal collecting performance
The high efficient selective layer is chosen as the film, the thermal efficiency can be up to 60%. By controlling the vacuum degree between the inner and outer tube and preventing the film attenuation, each tube is guaranteed for 15 years.
Thermal perservation in winter All-glass evacuated tube adopts vacuum insulation, and the thermal preservation of water tank is foaming of polyurethane at high pressure. The Tianjiao series are configured with energy saving standard, which solves the heat loss caused by the hear transfer, heat conductivity and heat radiation. Even though in the winter, it can still perform well.
Performance in summer
The film will transfer the solar into heat high-efficiently and the temperature can rise quickly. Because the pipe wall of the inner tube contacts with the water fully, the thermal conductivity can be smooth so that the overheating can be avoided.
Anti-dust performance
The outer surface of all-glass evacuated tube is smooth and the dirt is not easy to coagulate on it. Also the rain water can wash the dirt away easily, ensuring the sufficient sunlight transmissivity.
Film attenuation
By controlling the vacuum degree between the inner tube and outer tube and adding the getter, the chemical reaction of the film and active gas can be avoided. It can prevent the film attenuation and prolong the using ***n.
Appearance design and safety performance
Our products is designed through aesthetics, and the appearance can be changed according to the demand of the customers. Moreover, the frames need to undertake the strength test to meet the using requirement.
