Vitosol Evacuated Tube Collectors About the product

  • Highly efficient vacuum tube collector based on the heat pipe principle, with ThermProtect automatic temperature dependent shutdown for high operational reliability.
  • Protection against overheating during prolonged insolation.
  • Long service life due to low stagnation temperatures and prevention of steam forming within the system.
  • The absorber surfaces with highly selective coating, which are integrated into the vacuum tube, are not susceptible to contamination.
  • Efficient heat transfer through condensers fully surrounded by the copper Duotec twin pipe heat exchanger.
  • Optimum alignment with the sun, thanks to uncomplicated absorber alignment.
  • Dry connection, no contact between process medium and solar medium, i.e. individual tubes can be replaced whilst the system is fully charged.
  • Dark blue collector casing and absorber surfaces form a visually seamless appearance.
  • Highly effective thermal insulation of the header casing for minimum thermal losses.
  • Easy, quick installation with the Viessmann installation and connection systems
