Our production lines are as follows:
Nosta standard
Standardised parts for a power-transmission on the shaft-hub connection. Components for fixing and mounting.
Nosta connect
Optimal connecting elements in standard areas of DIN 508 in order to receive a perfect realisation of your individual ideas.
Nosta tailor made
In our tailor-made production we combine basic advantages by using tailored, complex, precise and individual compoments according to customers drawing.
Nosta rail
Due to our high quality standards and our reliability we are in the position to provide the railway supply industry with different mounting components during the last years.

AkoTec was founded in 2008 and is based in Angermunde, 80 km from Berlin.
From the absence of good products in the global market, there arose the idea to develop
and produce high performance, high vacuum tube collectors to produce thermal energy.
And AkoTec took birth.
More than 30 years of experience
Dipl.Ing (Engineer) Reinhold Weiser, General Manager of AkoTec and well known expert
of solar thermal systems has accumulated experience of 30 years in Solar thermal
products and system concepts.
He has played a significant role in the development of the NARVA vacuum tube.
Not to be beaten in Quality and Performance!
Process, products and complete collector assemblies are developed by AkoTec. All collectors
are manufactured in Angermünde.
The systems and collectors undergo continuous developments/ improvements to achieve
increased efficiency and cost reduction. Only then can we produce high end products
and cater to new applications like district heating plants and industrial process heat.
The automated processing of the collector elements, i.e. copper pipes ensure stable, high quality standards. Brazed connections are produced with the electric arc brazing process.
This procedure has very little burden/stress on the material, because the heat is very localized and deployed in targeted space. This ensures high size accuracy of copper parts.
With this technology, high quality products through mass production become competitive for all market segments. We can not only offer solar thermal systems for single- / multi-family-houses, but also for industrial applications like paint shops, hotels and laundry service.
All collector components 100% „Made in Germany“
This way we can ensure the best quality and logistics. Since the foundation of the
Co we have saved 4700 ton CO2 since our heating is 100% Carbon free.
Tested and Certified
Our full vacuum tube collectors are tested by TÜV institute for performance and hail impact resistance. The collectors have successfully undergone the intensified impact-from-hail test. Many insurance companies require this test. During this endurance test, 40 mm ice balls were shot with an impact speed of 100 km/h onto the collectors and especially the tubes. Furthermore the collectors are certified with the Solar Keymark.
Awarded
In the year 2008 the tube was awarded with the Innovation Prize. In 2012 we were honored
with the Future Award of Brandenburg.
All of this guarantees high quality and performance of our products.

SolarWorld AG has developed in just a few years from a trading company to a solar concern with integrated solar value chain process - from raw materials to the solar wafer, the solar cell, the solar module right up to ready, high-quality solar power plants.
Today, the company profits from the fact that it was early to set up the entire solar value chain: It has modern factories at all production levels to serve the solar market comprehensively. In addition, the company controls the development of solar power technology at all levels under its own roof.
The company employs more than 2,700 staff members in its locations in Germany, Spain, South Africa, Asia and USA - and this number is growing.
