                                           is the best physical insulator !


                                       •   Like in a thermos flask the heat can
 Double wall glass tubes                   be stored for a long time.
 + cylindrical evacuated
                                       •   This allows to operate the collector
 absorbers                                 with high efficiency even in times
                                           with low solar irradiation or at high
                                           temperatures.

                                       •   Due to the material (pure glass
                                           tube) the design is very durable.

Why water as the heat transfer medium?
• Long-term constant, ensures a long operational lifetime


• High heat transfer and conduction coefficient


• High temperature resistant


• Environmentally-friendly


• Cheep


• a small amount (< 1 % in Chile) is taken to keep the collectors
  frost free
