Solvivo

1. Absorber

The absorber consists of copper fins ultrasonically welded to copper ducts which provide optimum heat transference between fin and duct, which ensures high efficiency.

2. Covering of the Absorber

The copper fins are covered either with selective treatment through electro-deposition or with black chrome paint. Both allow for a highly efficient receiver surface.

3. Insulation

Foam of rigid polyurethane, of 30mm, which complies with US and Europe regulations, is located below and around the receiver surface area. A 20mm coat of mineral wool protects the polyurethane, thereby providing an additional insulation to maintain the heat in the receiver.

4. Solar glass

A single panel of solar glass, 3,2mm thick, designed to reduce the reflection and tempered to increase resistance and duration. Its low content in iron oxide (0.03%) allows a high solar transmission of 91%.

5. Casing

• Aluminium: the frame is constructed in extruded aluminium with slots which allows easy installation.
  

• Stainless steel: the stainless steel frame provides maximum protection against corrosion, which is particularly important in coastal areas with high percentage of salinity in the air.
  

• Galvanized steel: the galvanized steel frame comes with polyester epoxy finish.

6. Rubber draught excluder

The rubber EPDM draught excluder which surrounds the glass is highly resistant to variations in temperature and UV radiation. It absorbs the differential expansion of the frames and the glass pane.

7. Piping Network

Copper pipes of 12mm welded to the main ducts of 22mm with optimum flow distribution.

8. Connection of Piping

Four female B.S.P. bronze connectors

9. Back

The back is made of a sheet of black polypropylene.

10. Aluminium Sheet

Adhering to the insulation, the sheet acts as a protective barrier.
