The Heat Pipes series solar Collector are always connected with existing heating supply device, the selective coating on the inner cover or the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by aluminium Fins, The liquid in the heat pipe changes into vapour which rises to the condenser. The heat conducts to the heat transfer liquid vis a copper pipe. This transference of heat into the liquid creates aa continuous circulation as long as the collector is heated by sun.
A. Material: TU1, military industry copper, also called oxygen free copper. We do treatment in high pressure vessel with chemical treatment for better performance. This will keep the life of the heat pipe over 20 years and we give 15 years performance guarantee.
B. Condensor size: 24mm which give better heat transfer
C. Unique high tech. Welding and high vacuum degree
