New building: EXPO Centre Shanghai Extreme flexibility in hot water and auxiliary heating AURON DF AURON DF is a direct-flow vacuum-tube solar collector which has been developed for both domestic hot water and auxiliary heating. With regard to solar efficiency and collector annual return, AURON DF provides convincing, optimal results. The extreme flexibility of the mounting system guarantees optimal alignment towards the sun. Combined with the innovative hydraulic construction of the collectors, all variations relative to the roof, wall and ground are possible. By turning the tubes, the absorber surface can be oriented to provide the optimum angle to the sun.
