The CSV vacuum tube collectors are built using relevant glass tubes that have a vacuum inside; an ideal solution for the non-dissipation of heat. The absorber is positioned inside.
A special concentrator mirror allows absorption of energy even with solar rays that have an unfavourable angle of incidence; these collectors guarantee good yield even during periods with reduced solar exposure.

The CSV vacuum tube collector has the attachments on the same side, but the installer can choose the left or the right.

The air venting unit must be positioned on the hydraulic attachment on outlet from the collector (hot liquid outlet), in correspondence with the probe housing.
