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.

A Greslar está localizada na zona centro do País, em Boialvo, próximo da cidade de Anadia.
A laborar desde os anos 80, desde muito cedo iniciou a produção de cerâmica rústica. Presentemente a Greslar tem duas áreas de negócios, uma de produtos para o fabrico de lareiras, fornos e churrasqueiras, complementada com a comercialização de barro refractário, argamassa refractária e cimento refractário e outra para decoração de lareiras e de interiores (Construção) com toque rústico. Também estamos habilitados a fabricar produtos cerâmicos específicos de acordo com a solicitação do cliente.
Vendemos para todo o país, continente e ilhas, e exportamos para alguns países do espaço Europeu e Norte de África. Os armazenistas de materiais de construção e empreiteiros/construtor civil são os nossos principais clientes.

Wir haben derzeit ca.
40 Mitarbeiter, fertigen und montieren unsere Produkte mit eigenem
Personal. Unser Hauptgebiet liegt in der Planung, Herstellung und
Montage von Leichtmetallglasfassaden, Aluminiumfenstern und Türen,
Brandschutztüren in Stahl oder Aluminium, sämtliche Fenster und
Türarbeiten (auch für Innentrennwände) Blechkantteile und Fassaden.
Wir sind in der Lage, Aufträge von einzelnen
Fenstern bis zu größeren Objekten mit Auftragssummen von bis zu 2 Mio
Euro, termingerecht und qualitativ hochwertig, zu attraktiven Preisen
abzuwickeln.
Zur Planung stehen uns drei CAD-Anlagen (2D+3D) zur
Verfügung. Ein modernst eingerichteter Maschinenpark in einer neuen
Halle helfen uns, Aufträge sauber und einwandfrei abzuwickeln.
