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
