The vacuum heat-gathering tubes produced by the Sangli Company itself include the sizes of *7*1. 2M, *7*1. 5M, *8*1. 8M and so on. They 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 **8 degree with the comparatively strong credibility and everlasting capacity. 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****3Pa, the high light-penetrating rate of over *0%, 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 *0% absorbing rate and below 9% scattering rate). Temperature when it is empty can be upwards **0 degree. It can offer plenty of hot water over *0 degree in the winter with the temperature of below *8 degree. In summer, the temperature of water can be more than *5 degree. The outside surface of vacuum heat-gathering tube is smooth and stainless. The transition of the lower port of tube is smooth. The sealing is round and pointless. The pure-black reflecting rate of plating film is low. It looks showily and without the falling-off the film. The mirror is full and smooth, its color is sterling.
