Solar Collector Evacuated Glass TubeProducts Description

The evacuated tube is the key component to all the thermal heaters and system. It's similar to aconventional Dewar flask and consists of two borosilicate glass tubes, resistant to high chemical andthermal shock. The outer side of the inner tube is coated with a sputtered solar selective surface. Thiscoated inner tube is closed at one end and sealed at the other end to the outer tube. The annular spacebetween the outer tube and inner tube is evacuated to avoid heat loss in conduction and convection.The key element determines function of tube is the technology of the film coating, Gaia Solar tube is the best efficiency tube you canfind in China, with the highest absorptance rate of near 97% with common rate of 94% and lowestemission rate near 3% with common rate of 5%.

Advantage1.Higher efficiency collector, much lower heat loss with vacuum insulation;2. High pressure and super anti-freezing performance in cold weather condition;3. Less heat loss for closed loop circulation;4. No system drainage even though one or several tubes are broken;5. No risk of tube breaking from thermal shock;6. More convenient in system parts carring and installation;7. Can load 6960 pieces in one 40 HQ;8.Cheaper than other thermal conductivity.
