The company AkoTec production mbH was founded in 2008 with headquarters in Angermünde. 
In the absence of good products on the world market the idea, powerful full-vacuum tube collectors was 
to develop the production of thermal energy and produce.

More than 30 years of experience

Dipl. Ing. Reinhold Weiser, AkoTec managing and publicly appointed sworn 
appraiser Solar, could 30 years of experience in the field of solar thermal products and system concepts 
with introduction. 
He was instrumental in developing the full-vacuum tube of the east German company with Narva.

In quality and performance not to exceed

processes, machines and products are self-developed. All collectors are on 
site manufactured in Angermünde. 
The machines and collectors are constantly being developed in order to increase efficiency and 
achieve cost reduction. Only in this way it is possible to continue to provide quality products 
and new applications, such. as solar thermal district heating system or industrial 
process heat to open up. 
The automated processing of the collector elements, such as copper tube, guarantees consistently 
high quality standards. Solder connections are made ​​with the Lichtbogenhartlötverfahren. 
This process loads the material slightly, since the heat is very limited and targeted locally to 
come use. At the same time it guarantees high dimensional stability of copper parts. 
With this technology, high-quality products through mass production competitive for 
made ​​all market segments. We can solar thermal systems for single-family / multi-family houses, 
but also to offer commercial applications such as paint shops, hotels and laundries.

All collector components 100% "Made in Germany"

Thus, we can not offer only the best quality, but still bear effectively to climate and 
environmental protection. Since its founding, our collectors have 4700 tons of CO 2 saved. Because of 
our heating panels is carried out 100% CO 2 free.

Tested and awarded

our full-vacuum tube collectors have been tested by TÜV Rheinland in performance and durability. 
They have been subjected to stringent testing and hailstorms have passed successfully. This test 
call now most insurance. During this stress test 40 mm wide are 
ice balls with an impact velocity of 100 km / h on the panels, in particular 
, shot the tubes. They are also certified Solar Keymark and therefore eligible from the Bafa.

Awarded
in 2008, the tube was honored with the Innovation Award. In 2012 we were awarded the 
German Future Prize awarded Brandenburg. 
All this speaks for the quality and performance of our products

Applications

The sun is at least daytime ubiquitous and is available to any charge. The total on the surface
incident energy amount is more than ten thousand times greater than the energy demand of mankind. The potential is greater
than that of all other renewable energies together.

Why do you do then this energy source does not advantage?

A solar thermal system with highly efficient vacuum insulation can help the cost trap to escape. The
running costs are zero because no raw materials are used. In addition, the heat is generated emission-free.

With a solar thermal system can complete water heating secure and your existing heating
support . In the commercial sector, the solar heat can be used, for example for the production of process heat .
Even a whole village may by means of a solar thermal local heating network are supplied with heat. Here
the solar thermal system is used as a small self-sufficient heating.

The principle of heat recovery in our full vacuum tubes is simple:
water flows in a full vacuum tube through a thin copper tube. In addition, there is a blue colored plate absorber
made ​​of copper, which absorbs the sun's heat. The water in the tube is heated. The vacuum in the tube ensures optimum
insulation and ensures that the total heat is transferred to the memory. The panels have an efficiency
of 80 percent. That is the main difference from the solar panels to generate electricity. These have an efficiency
of 20 percent. Especially with heating support systems or solar houses the effectiveness of the vacuum insulation comes
into play.
