We are professional solar and recycling energy manufacturer and supplier in china, our product line including non-pressure series solar water heater (one pipe inlet-outlet/two pipe inlet-outlet solar water heater), pressure series solar water heater (Pre-heated solar water heater/Pressurized solar water heater/Double tank solar water heater), Split solar water heater (U pipe type solar collector/Heat pipe type solar collector/Split pressurized water tank/The accessories), All-glass evacuated solar collector tubes, solar collector manifold, glass evacuated tubes and heat pipe and so on.
--------------------------------------------
This product is the All-glass Evacuated Solar Collector Tube(solar vacuum tubes/solar evacuated tubes)
The all-glass evacuated solar collector tube consists two concentric cylindrical glass tubes, the inner cylindrical tube is the absorber tube on which solar selective coating is sputtered, the jacket between the two glass tubes are evacucated to extremely low vacuum to reduce the heat loss by free convection and conduction. Top quality tubes increase the solar yield of your solar system and reduce the aging problem. This technology can be utilized under all kinds of climate conditions, especially better in colder area.
Features of this All-glass Evacuated Solar Collector Tube
High absorptance a>0.93 (AM1.5) and low emittance e<0.06 (80 Celcius degree);
Borosilicate glass 3.3 with transmittance higher than 91%
Long service life by ensuring vacuum integrity;
Quality manufacture ensures standadized tube with uniformity and reproducibility;
Private Logo accepted.
