Technical characteristics of ATLAS solar collectors

• Copper & aluminum are the materials used, which are non-corrosive, ensuring a lifespan of many decades. There are no steel parts that corrode
• Frame made of high aesthetic aluminum profile, with external corner connectors that ensure perfect fit & sealing of the frame parts & the high rigidity of the entire construction.
• Absorber with a selective surface made of 4 mm thick aluminum sheets with a special titanium oxide coating. The coating is done with special vacuum processing in Germany. The solar radiation absorption surface is in perfect contact with the copper hydraulic skeleton, welded with automatic LASER machines for immediate heat transfer to the thermal fluid. This ensures a very high absorption coefficient α>95% & a very low emissivity coefficient ε<5%, contributing to the maximum thermal efficiency of the collector.
• Back of the collector made of aluminum sheet that ensures complete sealing against the frame without rivets.
• Safety glass tempered low iron with a thickness of 3.2 mm.
• Thermal insulation made of fiberglass with a density of d=30kg/m3 at the back of the collector (back).
• Oval rubber gasket specially designed and adapted to the copper connection pipes of the collector to prevent thermal bridging between the frame and the copper pipes due to thermal expansions and contractions.
