Solar Collector Atmosfera SPK-F3

High-performance flat-plate collector SPK-F3 is ideal for seasonal work in conditions of high solar insolation. Highly selective absorber Almeco-TiNOX (Germany) SPK-F3 collector has a 100% uniform coating across the width of the plate, pogloschyayuschee energy up to 95%, radiant heat energy is not more than 4%. The high thermal stability of the absorber (up to 295 ° C) allows the system to withstand the regimes of stagnation without harm to the collector and the system. Laser welding of copper tubes with the plates of the absorber provides a heavy-duty and complete the assembly of parts. Mounts on any surface. Housing SPK-F3 is made from high quality corrosion-resistant aluminum alloy. The case is assembled without the use of screws and rivets, which ensures reliability and durability.
