Vacuum tubes made in Germany
NARVA carried out the step in solar technology in mid 2007.
About a million vacuum tubes can be manufactured here per shift and year with a new plant.
NARVA carried out the step in solar technology in mid 2007.
About a million vacuum tubes can be manufactured here per shift and year with a new plant.
Due to NARVA’s 40-years of experience in the field of glass manufacture and processing, their extensive knowledge about coating and vacuum processes, as well as experience in the field of glass-metal-compounds, they have been able to realize the production and process very quickly.
Especially the patent-protected glass-metal-compound between sheathing and absorber makes the product robust and durable. Through the coating with nano-particles, the transparency of the glass is once again considerably improved and with that, the effectiveness of the tubes.
The certified production in Brand-Erbisdorf includes all the essential production stages. The tube is made at the company’s own glass factory; the prefabrication manufactures the copper absorber units. The assembly of both parts for the finished product takes place at the new plant which was put into operation in 2007.

Innovation award
for NARVA product
At the 18. Symposium Thermal Solar Energy, held from 23rd to 25th April 2008 in Kloster Banz – Bad Staffelstein, NARVA received the award of innovation for its product vacuum tubes.
Decisive for the award to NARVA was an evaluation with regard to:
• Innovation
• Energetic relevance
• Market relevance
• Issued property rights
Prof. Dr. Goetzberger, speaker of the jury, particularly pointed out in his laudatory speech that with the NARVA tubes, a product is available which is excellently suitable for the solar process heat market. This area of application usually needs higher temperatures which are best achieved with the use of collectors with vacuum tubes.
