The internal hydraulic circuit is made of Ø 18×0.7 mm copper connecting pipes with ¾”M welded couplings in each glass tube by an equal number of Ø 8×0.6 mm U-bent copper outlet and return pipes in which the solar heat transfer fluid flows for heating.

The entire external structure of the collector is made of anodised aluminium while the side closures on the collector are made of thermoplastic with slots to allow natural air circulation inside the collector head and eliminate internal condensation that could form during the winter, thus protecting the insulation from deterioration.
Reversible collector with water coupling and temperature probe ready on both sides.

PARALLEL CONNECTION WITH THE ADDITION OF AN INTEGRATED THIRD TUBE
Thanks to the third tube and the third coupling with the X-RAY 10 R collector, 8 collectors can be connected in parallel in a single string, creating a single collector in terms of energy.
With the hydraulic connection systems, creating the connection between each panel is extremely easy, quick and efficient, with “no welding or special tools” required. The connections also function as expansion joints besides ensuring an excellent view of the system due to the lack of piping on the roof.
