Highly efficient vacuum tube collector based on the heat pipe prin ciple, with ThermProtect automatic temperaturedependent shut down for high operational reliability
The absorber surface with highly selective coating integrated into the vacuum tubes is not susceptible to contamination
Efficient heat transfer through a condenser fully surrounded by the heat exchanger
Vacuum tubes can be rotated for optimum alignment with the sun, thereby maximising the energy utilisation.
Dry connection, meaning tubes can be inserted or changed while the system is full
Highly effective thermal insulation for minimised heat losses from the header casing
Easy installation through the Viessmann assembly and connection system
