1.All Glass Vacuated Tube
All glass evacuated tubes are the key component of solar collectors. The evacuated tube is similar to a conventional Dewar flask and consists of two borosilicate glass tubes, a glass with high chemical and thermal shock resistance. The outer side of the inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to virtually eliminate heat loss by conduction and convection.
We use the tubes which use the successfully developed innovative Advanced Solar Selective Coatings in commercial scale, which achieve the highest thermal efficiency and good thermal stability. Solar selective coatings absorb most solar radiation while simultaneously suppressing the thermal emittance loss from coating surfaces. They vary mainly in their optical property and thermal stability.
Excellent results have been obtained by using DC magnetron sputtering technology. A solar absorbance of 0.94 - 0.96 with an emittance of 0.04 - 0.06 at 100 centigrade has been achieved.

The evacuated tube is a product with improved geometry and performance and consists of two concentric glass tubes which are sealed in a semi-circular shape on one side and are joined to one another on the other side. The space between the tube is evacuated and then hermetically sealed (evacuated insulation). To use solar energy, the internal glass coated with an environmentally friendly, highly selective la er on the outside, thus turning it into an absorber. The coating is protected in the evacuated space. The aluminum nitride sputter coating used is characterized by an ex u extremely low emission and a high absorption rate

They are ecological systems, where natural light is captured and directed through internally coated tube by highly reflective material, which minimizes the dispersion of the rays and allows a supply of light at considerable distances, without heat or cold transfer.
SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE - Capture, Transmission and diffusion of natural lighting. Chatron's SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE are systems for capturing and transmitting natural Daylight to the interior of the buildings where they end with the solar diffusers. The dome is placed on the outside and maximizes the capture of natural light that will enter the SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE and route it to the solar diffuser placed inside the installation. In the background it is as a Light Tunnel. The great advantage is that it can bring natural light to spaces that were otherwise was practically impossible to illuminate: lighting for indoor bathrooms, corridors, cellars etc. The domes, SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE and solar diffusers have unique and selective features, so they transmit the good light and eliminate harmful light (UV, and part of the Infrared) so that the heat or cold transmission to the interior is residual.
