Sunstar DF 100

Our Sunstar DF 100/6 collector belongs to the series of direct flow high vacuum tubes.Herein, the particular tubes are directly flushed with the heat carrier medium. Therefore, these collectors can be used universally – horizontal or vertically, from 0 to 90 degree roofs to facades as well as in stand alone installations. The Sunstar DF 100/6 allows creating all conceivable vacuum tube solutions: No matter if flat on the roof, integrated in a façade, a balcony balustrade or as half shadow for the porch.

Key data:

  • Tube diameter 100mm
  • Direct flow full vacuum collector
  • For facades, flat roofs, balcony balustrades
  • The absorber can be adjusted to an optimised angle to the sun
  • High low light yields with fast reaction
  • Very high yields in cold environments (winter)
