All-glass solar vacuum collector tubes

• Φ 47 series

• Φ 58 series

The advantage of our vacuum tube

A. We select the selective absorbing painting lever to cover the outside surface of the inner tuber, which forms the heat absorber. Thus, they can transfer the solar energy to the heat energy, and have the high absorbing rate while the low cooling rate. In addition to the above, they also can beat the strike of 2.5CM hails and the strong coldness of -18 ℃ with the comparatively strong credibility and everlasting capacity.

B. Vacuum heat-gathering tube of solar energy is the heating organ of the key part heater with solar energy (the extra high vacuum degree higher than 5*10-3Pa, the high light-penetrating rate of over 90%, the raw material of extra hard glass with high intensity that can compare with the American pyrix, and the vacuum plating film by spattering with over 90% absorbing rate and below 9% scattering rate). Temperature when it's empty can be upwards 200℃ . It can offer plenty of hot water over 40℃ in the winter with the temperature of below 18℃ . In summer, the temperature of water can be more than 95℃ . Thus, it can be used continuously for 15years.
