All-year highly efficient high-vacuum tube collectors
Based on their hydraulic properties, DF collectors are able to be integrated on any building (pitched roof, facade or even free standing). The s-power collectors are used for solar drinking water, pool heating, furnace support and process heat. The s-power DF tubes carry a coaxial heat-extraction-pipe (pipe within a pipe). The to be heated heat-carrier-fluid runs from the header through the inner pipe towards the lower part of the vacuum tube and then through the outer pipe (outer heat pipe) back towards the header. On its way back to the header, the heat is transferred from the outer pipe, which is connected to the absorber, onto the heat-carrier-fluid. All vacuum tubes are axial adjustable towards the sun and can be individually exchanged. The innovative plug-in connection system of the tubes allows them to be fast and securely assembled inside the header. Their modular concept allows the collectors to be fast and easy installed onto the building.
The s-power DF (Direct Flow) collectors are „real“ all seasons systems with exceptional yearly solar earnings (kW/m²/a). They therefore set new standards in the area of diffuse irradiation. The one-of-a-kind anti-reflex-coating (nano-coating) applied onto the inner and outer side of the glass tube allows for an extraordinary high light transmission (~97%), a very low light reflection (~3%) and therefore outperforms all standards so far. The high performance-copper-absorber, which is coated with Titan-Nitrid-Oxide (TINOX), absorbs the sunlight highly effective. (~96%). The absorber is welded onto the heat-carrier-pipe using ultrasound-welding. The patented, innovative glass-metal connection grants for highest quality measures (10 years warranty by the manufacturer). The glass-metal connection seals the glass tube to preserve the high-performance-absorber-unit enduringly under a vacuum of 10-5 mbar (100% Insulation).
