Description: Product Name evacuated tubes for solar water heaters Brand SUNRAIN Country of Origin CHINA Product Description By using the advanced meltage technology from the abroad and the strong industrial link, our factory produces high quality borosilicate glass tube. The borosilicate glass invented by the Corning Co. in 1915 is called ?the Glass King? which reaches to the standard of USA ASTM-E438 and ISO 3585:1991. For the perfect thermal expansion coeffient, it can be against the strong temperature fluctuation. And for the good chemical steadiness parameter, the borosilicate is not harmful to end-users. specifications A.TYY-AA series: It has the advantages of high absorption (0.86-0.92/AM1.5) and low emittance (?0.08/80???), which is invented by Yin Zhiqiang, Professor of Tsingua University, and used in the civil solar water heaters extensively. Its selective absorption layer adopts the graded AL-N (aluminum nitride) cermets layer. Its film structure is AL-N/AL-N/AL-N/AL/AL-N(adhesion) which can work effectively with the temperature of 200?.B.TYY-MC series: We developed the rotary three-targets magnetron sputtering technology together with the New Energy Center of Peking University and used it to produce TYY-MC series (Double M-ALN cermets layers) tube which has the advantages of highest thermal efficiency (0.96); lowest emittance rate (?0.04/20?) and working effectively with the high temperature of 300-350? in the contrast to the normal evacuated tube. The corresponding film structure is ALN/M-ALN(LMVF)-M-ALN (HMVF)/Cu.LMVF:LOW METAL VOLUME FRACTIONHMVF:HIGH METAL VOLUME FRACTIONC.TYY-P series: We can produce TYY-P series, which combine the heater tube and vacuum tube. It transmits the thermal energy quickly and can work against the high pressure. And it may prevent the tube from being destroyed by frost while it works in some extremely cold area.
