1.Distinctive Technology for High Heat Preservation
The multiple-target film coating technology is adopted to produce the evacuated tube collector to keep its vacuum level rated over 10-4Pa. And the polyurethane high-pressure sparkling technology is adopted to integrate the evacuated tube collectors and the seamless water storage tank together to form a complete closed loop system. So maximum solar-thermal conversion and minimum heat loss are really assured, and the period of heat preservation can reach 72 hours. 3.Excellent Water Storage Tank
The inner tank is made of high quality stainless steel rated at SUS3042B, and sealed by the automatic computer-controlling straight-seam welder and the automatic computer-controlling thermojunction welder to assure perfect jointing. The outer shield is made of heat aluminium-plating and zinc-plating boards imported from Luxemburg by the unique inside-finished technique. So the water storage tank is featured with firmness, endurance, good taste, acid and alkali resistance, and strong anti-corrosion.
2.Novel Film Coating Technology for High Photo-thermal Efficiency
The unique double-target or multiple-target film coating technology is adopted to facilitate the evacuated tube collectors with the following advantages: (1).High working temperature (350℃); (2).High absorptance (0.93～0.96); (3).Low emittance (0.04); (4).Strong assimilation capacity of infrared ray; and (5). Operating normally under overcast sky, and even under negative 35℃ with the tubes not exploded. 4.Long Life-span Support Bracket
For the purpose of firmness, elegant appearance and long life-span, the support bracket is made of imported cold–rolling zinc board which is handled with pickling, phosphating, plating and spattering technology to guarantee its performance of acid resistance, anti-corrosion and rust resistance. The glistening board is made of high quality oxidated aluminum with the features of high diffuse reflection, withstanding wind and snow.
