• According to the materials of the tubes: 
  • with aluminum tubes
  • with cooper tubes

• According to the materials of the absorber surface: 
  • with aluminum wings
  • with cooper wings

• According to the coating surface: 
  • mat black paint
  • selective pain
  • black chrome
  • tinox


• According to the type of the glass: 
  • normal glass
  • prismatic glass

   The vacuum in the tubes is 5х10^-3 Мра, the best insulation. This make them very effective in the winter when the temperatures are very low. This is the main priority property in comparison to the flat collectors

   There is no need to clean the tubes because dust and snow cannot stay on it.

   The vacuum tubes KINSLY 70/1700 are made of high quality borosilicate glass with thickness 2.5 mm and hail resistance 35 mm.

   The individual direction make the tubes very effective whole day.

   The dry connected tubes are without working fluid in them. This make them very effective in very low values of sun intensity.

   This is the main difference between them and the wet connected vacuum tubes or the flat collectors in cloudy whether.

   The vacuum tubes with dry connection are made for easy changing each separate tube and there is no need to interupt the work of the system.

   The stand is made of Cr-Ni material protected against corrosion and wind resistance 30m/s. The heat exchanger is made of Ch-Ni steel, polyurethane insulation, aluminum sheet and stainless steel external jacket.

• The vacuum tubes are type-dry connection. In comparison with other types of vacuum they have few priorities Properties: 
  • they are with higher effectiveness
  • there is no water in the tube
  • the heat transfer liquid is non toxic non freezable in closed system
  • in case one or more tubes taken of there is no leaking and the collector and the system still working
  • if there is a broken tube there is no need то empty the liquid from the system
