With our high efficient solar collector you will increase your solar yields to the maximum with
perfect price-performance ratio.
We have optimized our SUNSET-Primus. Now, due to the new connection method, the
mounting is even faster and easier as well as the handling because of the light weight.
The Absorber
The water-bearing copper tubes are laserwelded to the absorber and hence ensure
a max. heat transfer.
The innovative absorber connection via
elastic spacing strips guarantees a precise
and solid stabilisation of the absorber. The
defined distance between absorber and
the glass enables a constant efficiency
during operation. By this a contact between glass and frame can be excluded.
The coating
Another highlight of the SUNblue® series
is the high efficient and environmentfriendly coating. The absorption rate of the
solar-radiation is 95%, with only 5% emissions.
For comparison: a common blackchrome
coated collector has an absorption rate of
approx. 90%, with 10% emissions.
During the production process only a minimum of energy is required and no pollutants or harmful substances are produced..
The casing
The self-supporting collector casing is
made of molded aluminium and is silver
powder-coated. The back board is protected against mechanical damages
trough structured aluminium plates.

Glass
The front glass is a 3.2 mm thick solar
safety glass. Due to its low iron content of
0,03% it has a high light transmission of
92%. The prismatic inside prevents losses
of efficiency trough reflection of the heat
radiation. To ensure a high breakproofness and steadiness, the glass is
heat tempered and protected against
wind speeds up to 250 km/h.

The collector can be mounted on-roof or
roof-integrated on sloped roofs, as well
as elevated on flat roofs.
Isolation
The isolation is made of a 50 mm thick
environment-friendly mineral wool. The
edges are completely isolated and free of
thermal bridges.
