The characteristics of the Solar Collector, produced
and distributed by
PÉTER IMPEX Ltd.
· The
solar collector designed and released by PÉTER IMPEX Ltd. is protected
by the number 000838586-0001 / 000838586-0002 / 000838586-0003 community
design patent statement, and number U 06 00268 utility model patent,
furthermore the P 07 00564 number patent was applied, therefore is a
product protected by law. This collector is a flat collector, and its most
important characteristic, which is absolutely different as compared to the
general types, is its technical solution, where the heat-absorbing surface is
the same with the heat-transferring surface, thus ensuring an extreme heat
performance and the highest achievable efficacy.

· There
is no mediatory element between the absorber heat transferring surface and the
heating medium, therefore there is no galvanic rusting, which would work as an
insulation, there is no bad pressing, bad assembling, which would result in
lowering the efficacy of the system.
The main element
of the collector is the special alloyed aluminum plate profile, which is
pressed in warm conditions just for this reason, and in which a small depth of
liquid channel is made through plating. The panels are fixed parallel at a
distance from each other, the endings are fixed into the distributing and
collecting pipe area, this way ensuring an ideal 1,7 l of cubic capacity, and the two inputs and two outputs.
· Our
product’s other important characteristic is a homogenous and exclusive alloyed
aluminum material, made and used especially for this purpose, which possesses a
very good heat conducting capacity (235 W/m°C), is long lasting, resistant to
corrosion, its mass is small (less than 2,8 kg/dm3), it is
easy to work with, easy to assemble, and it is relatively cheap.
· The
third, and other important characteristic of our product is the surface
treatment of the solar collector, different from other products.
The surface
treatment of the alloyed aluminum plate, used by us is unpolished black elox,
which can absorb the Sun’s rays at a relatively high amount (approximately
85%), and its specific heat emission capacity compared to its temperature is
relatively low (15%).
The elox coating
is taken up through electro-chemistry way, making its surface more endurable,
since on the surface a 10-18 micron thick solid metallic oxid-layer is shaped
up. This solid layer is insulating electrically, therefore it rules out the
possibility of galvanic rust, on the other hand is aesthetic, its heat
insulation is insignificant, its efficiency is very high.
· The
collector house is a very important element of the collector, which usually is
made of aluminum panels. Its task is the covering and heat insulation, keeping
the absorber in a closed unit, closing down the collector, and preventing the
humidity entering the collector. Making the collector house was an important
aspect of our company, therefore we used a specially alloyed aluminum panel
profile. Its advantage is thanks to its size that the collector is aesthetic and
its mass is lowered, its thickness is only 6,1 cm, its outer size is 2,0 x 1,0 m, its mass 38,6 kg. The bottom of the collector house is an
alloyed aluminum panel rolled in a cold manner.
· The
other important element of the collector is the closing glass panel. Its task
is to let the sun pass through and also hold it back through its good quality
transparency panel (in our case: 1,94 x 0,94 m), and with its heat insulation capacity reduce the convective heat waste of the absorber panel.
Usually high
purity, content low in iron, tempered anti-reflexion solar glass is used, and
this is applied to our product, as well.
The tempering and
thickness of the glass (4 mm) ensures that it does not get broken during the
transportation and installation, and resists the snow layer and the heavy hail.
· In
order to rise the efficiency of the solar collectors, normally heat insulation
is used, which is generally mineral cotton. Our company is using polystyrene together
with heat reflecting foil, or a combined mineral cotton – polystyrene heat
insulation.
· In
the case of the collector an important element was to be dismountable, its
parts to be exchangeable, and also the inner capacity’s vapor can be abandoned.
