System description
Technical characteristics
EGO PRIME
solar collector with integrated storage is used for producing domestic water that is heated by solar power, to temperatures below boiling at atmospheric pressure in places where
ice does not form.
It is not be used for the integration to the heating of buildings, for the heating of swimming pool and process water.
THE SYSTEM IS MADE UP OF TWO INTEGRATED UNITS:
Note on the integrated storage
system
The
EGO PRIME
solar collector with integrated storage
was produced pursuant to the 97/23/EC Directive (PED) for
pressurised equipment, in relation to the fluid and working
conditions to which it is exposed.
It is a container that holds a group 2 (water) fluid, with steam
pressure at the maximum acceptable temperature below 0.5 bar
in addition to the atmospheric pressure (1.033 bar).
As its threshold limits are below those indicated in art. 3.3 of
Directive 97/23/EC:
−“...for fluids in Group 2 with a pressure PS greater than 10 bar
and a product of PS and V greater than 10 000 bar 7L, or with a
pressure PS greater than 1 000 bar (Annex II, table 4)...”;
−“...piping intended for fluids in Group 2 with a PS greater
than 10 bar, a DN greater than 200 and a product of PS and DN
greater than 5 000 bar (Annex II, table 9)...”
this tank is not subject to CE marking, but the producer
guarantees it (as established in the directive) because “designed
and produced following a correct construction procedure”;
the accumulation system does not require CE marking.
A. The solar collector;

The supporting frame of the collectors is made of galvanized steel.

The external protective structure is made of alluminium case
1
, light and resistant.

The transparent cover is of LEXAN®
2
, a 10 mm twin wall polycarbonate sheet that has been an-
ti-UV treated. In comparison with traditional solar glass, the sheet is 80% lighter, it limits heat di-
spersion at night, it guarantees optimal transparency to solar radiation and it increases resistance
to bad weather.

The lower thermal insulation is made of a polyurethane foam panel, 30 mm thick, that is coated with
sheets of aluminium; the lateral insulation is made of 4 sheets of natural fibre polyester, 25 mm thick.
B. The storage
y
y
The domestic water accumulation system is made of a series of high-performing stainless steel cylin-
ders
3
made of a special alloy that resists high pressures and also very corrosive water.

The cylinders are closed at their ends by special caps
4
made of thermoplastic material loaded with
glass fibre, to unite lightness and resistance.

The caps are connected to each other by copper connecting pipes, which allow the water to move from
one cylinder to the next.
The supports for flat roof
