A high performance vacuum tube collector
- 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 double 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 whole
- Highly effective thermal insulation of the header casing for minimum thermal losses
- Easy, quick installation with the Viessmann installation and connection systems
