X Ray Installation Manual

TECHNICAL MANUAL INSTALLATION INSTRUCTIONS AND START-UP

DESCRIPTION The panels with X-RAY R tubes have three main pre-assembled components: ~ Vacuum tubes; ~ Curved CPC mirrors; ~ A collector with a heat distribution unit and integrated return tubing

Each vacuum tube is composed of two concentric glass tubes; every single tube is closed at one end by a hemisphere, and is connected with another tube at the other end. The vacuum is created in the space between the tubes. The recipient which is thus formed can be considered a heat recipient. To more effectively store the solar energy, the internal glass tubes (protected by the hollow space containing the vacuum) are coated with aluminium nitrite, which allows the tubes to capture the heat very efficiently.

Highly reflecting CPC (compound parabolic concentrator) mirrors, resistant to atmospheric agents, have been placed behind the vacuum tubes to further increase their efficiency. The geometry of the mirrors allows both direct and diffused sunlight to hit the captivating surface even when the rays of the sun strike them at an unfavourable angle. The input and return tubes are located in the upper part of the panels. The input tubes branch into heat absorption units; these are U shaped copper ducts provided with heat deflectors in sheet aluminium, which transfer the heat from the glass tubes to the U shaped tubes through which the vector liquid flows. The hot liquid flows through the tubes and reaches the heat exchange unit for the production of hot water for domestic use or to supplement the central heating system.

The vacuum collectors are supplied completely pre-assembled and therefore they are fast and easy to install. They are a reference point for the solar market thanks to their physical resistance, energy performance and exclusive design. The exclusive hydraulics of the X-RAY R collectors with a built-in third tube allow for connecting up to 6 solar panels in cascade mode, with the extraordinary advantage that an external return line is not required. This drastically reduces the installation cost and time, and guarantees a hydraulically balanced system with a clean and elegant line. Installation is possible thanks to the anchorage system which allows for installation on any type of surface. The third lateral connection allows for integrated hydraulic connection, with parallel hydraulic distribution which improves the energy performance compared with normal panels connected in series.
