Selective surface aluminum sheet 4mm thick with titanium oxide coating. The coating treatment is produced in vacuum in Germany. The absorption surface is in perfectly connected with the copper tubes by welding in automatic LASER machines for direct heat transfer to the thermal liquid. Its properties ensure the maximum thermal efficiency of the collector by achieving an absorption coefficient of α>95% and an emissivity coefficient e<5%.

Made of 0.8mm thick aluminum profiles of high aesthetics, advanced design, with external corner connectors that ensure excellent fit and tightness of the frame parts as well as great sturdiness of the collector. The back of the frame is made of 5mm aluminum sheet, the application of which is achieved by an automatic pressing machine, ensuring tightness and robustness.

Tempered Low iron Glass with 3.2mm thickness.  Low iron content has the advantage of low reflection resulting in higher absorption. At the same time, it is a safety glass that resists hail and falling objects. On the edges of the glass, a special aluminum profile is applied as a clasp and with the additional application of the special EPDM rubber make it completely waterproof and completely sturdy. 

Glass wool with a density of d=30kg/m3 which is placed on the back of the collector. We achieve the lowest possible thermal loss. In addition, the specially designed rubber gasket for the application to the copper pipe outlets prevents the creation of a thermal bridge between the frame and the pipping, while at the same time absorbing contractions and expansions due to temperature changes.
