Solar Vacuum Tubes


  • The Kwiksol Solar Vacuum Tubes consist of two glass tubes manufactured from borosilicate glass.
  • The outer glass tube is transparent allowing light rays to pass through it with minimum reflection.
  • The inner glass tube is coated with a solar special selective coating (Al-N/A1), which provides excellent solar radiation absorption.
  • The top of the two vacuum tubes are fused together and the air is extracted, which forms a vacuum and is key to the efficiency of the vacuum tubes.
  • To maintain a vacuum between the two vacuum tubes, a barium getter is used. The barium layer also provides a clear visual indication of the vacuum status. The silver coating will turn white if the vacuum is ever lost.
  • Anodized Aluminium frame and manifold.
  • Working pressure up to 600kPa.
