- Vacuum tube collector according to the
thermos flask principle, therefore very less
heat losses and higher solar gain
- Additional CPC mirror behind the tubes
increases the energy gain, especially in
transitional periods
- High operating reliability because of dry
connection of the tubes and leak-tightness
control (barium getter)
- cost saving and easy installation because the
still pre-assembled collector on the mounting
frame
- flexible choice of collector field connection,
single- and double-sided connection possible
- long lifetime through high quality
