Evacuated tube

    

  • Each tube is consists of two layer of glass tubes.
  • The outer tube is made of extremely strong transparent quartz sand which can resist impact from hail up to 25mm in diameter.
  • The inner tube is also made of quartz sand, but it is coated with a special selective coating with strong heat absorption and lowest heat loss.
  • The air is evacuated from the space between the two glass tubes to form a vacuum, so it  eliminates heat loss.
  • This why the tubes are able to absorb the energy from infrared rays which can pass through clouds.
  • So it also can operate in low temperature and low sunlight medium.

All-glass tube can resist impact from hail up to 25mm in diameter,
and eliminates heat loss
