Manufactured by:HaiYan ReDao New Energy Co., Ltd. based inHaiyan, CHINA
This type uses the all-glass evacuated solar collector tubes as the heat-absorbing element. The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission which is caused by convection and conduction. The layer films(coating) of the all-glass evacuated tubes transfer the sun energy into heat energy. The high absorption and low emittance rate of film is ...

Working principle: embraces tightly the U copper pipe with solar fluid.The fin touch precisely to the inner glass tube and transfers it to the solar fluid inside the copper pipe.the entire inner surface of the evacuated tube and header pipe. An aluminum fin conducts heat from tube) and when warmed up,it returns up to the which inserted inside the vacuum tube (evacuated The fluid passes through ...
