Product Description
Detailed product description:
Vacuum tubes assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass, gradual change of aln/ain-ss/cu selective complex absorptive coating. And these make vacuum tubes have high performance of absorptance and low reflection ratio. Through
The interlayer, vacuum has a unique effect of thermo, with its temperature up to 380º C of idle sunning, performing a strong heating ability.

Specification of all-glass evacuated solar collector tubes
1). Structure: All glass concentric dual tube geometer
2). Glass material: Borosilicate glass
3). Lifetime >15years

Solar collectors Vacuum-Pipe
Vacuum solar panels are made of any vacuum solar tubes with a diameter of 58 millimeters, providing excellent insulation being situated inside each tube absorber, zespolonemu with a specially designed tube HEAT PIPE. Independent pipes are connected to the massive copper head collector, in which heat is transferred to the solar system.

The use of independent vacuum solar tubes is important not only for outstanding performance collectors, but it is also a very safe option (in the case of mechanical damage to the collector can replace a single vacuum tube, while the entire solar system is operating normally).

Another advantage of vacuum solar collectors is their ability to concentrate diffuse solar radiation, which means that these collectors capture every, even the smallest amount of available solar energy to turn it into a free thermal energy. In practice, this means maximizing the efficient operation of the collectors of the period during the year (compared with other types of solar collectors), and thus, greater savings for you and your family.
The variables, Central European climatic conditions is important to the low thermal capacity of the collector, which means that the same collector requires a very small amount of solar energy to begin to produce heat for you. This means that regardless of the outside temperature, you can convert every available ray of heat in the precious thermal energy!
