1.23 TECHNICAL CHARACTERISTICS
SOLARSMART solar collector with integrated storage
is used for producing domestic water that is heated by
solar power, to temperatures below boiling at atmo-
spheric 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:
A. The solar collector
- The supporting frame of the collectors is made of aluminium
profiles.
- The external protective structure is made of a light heat-sealed
PVC frame
1
, that resists UV rays.
- The transparent cover is of LEXAN®
2
, a 10 mm twin wall
polycarbonate sheet that has been anti-UV treated. In compari-
son with traditional solar glass, the sheet is 80% lighter, it limits
heat dispersion at night, it guarantees optimal transparency to
solar radiation and it increases resistance to bad weather.
- The upper frame is made of heat-sealed PVC
3
, that can be re-
moved to access the accumulation tank. Light and UV-resistant,
its design makes it suitable for any architectural context.
- 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
- The domestic water accumulation system is made of a series of
high-performing stainless steel cylinders
4
made of a special
alloy that resists high pressures and also very corrosive water.
- The cylinders are closed at their ends by special caps
5
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
6
available in the following model:
– BASIC SUPPORT: pair of galvanised sheet supports (supplied
standard);
Note on the integrated storage system
The SOLARSMART solar collector with integrated sto-
rage 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.
