The Components

The body is composed of copper with fins welded onto tubes :

- Ø 8mm for pump circulation installations,
- Ø 12 mm for thermosiphon installations (without pump) and assembled on grids with Ø 22 mm. manifold tubes, ensuring an excellent heat transfer.

Selective coating
- The selective coating of absorbers is carried out by anodisation with black chrome.
- In order to meet the U.E Commission's recommendations to not use chrome, which is highly toxic, Jacques Giordano Industries has designed a new selective coating of the absorbers : the CuMOX. This coating does not use chrome at all (see data)

The CuMOX is optional.
. Absorption factor : α = 0.95 ± 0.01
. Emission factor : β = 0.20 ± 0.01

The C8 selective solar collectors are delivered with all the hydraulic fittings and assembly accessories from 2 to 24 m2 to accommodate any kind of roof or terrace surface
