NARVA - Vacuum tubes for the Solar thermal

Expertise in the fields of glass production, vacuum technology and coatin technology as well as awareness of sustainability and the environment led NARVA to the area of solar thermal applications. Know-how in the technically highly similar processes has subsequently reduced the development time of NARVA vacuum tubes to just two years.

2007 saw the first vacuum tubes with direct flow leave the fully-automated pruduction line. NARVA works continuosly to increase the efficiency of the vacuum tubes. The result is multiple trademarks and a high-performance heat pipe with a particularly high level of efficiency. This especially attractive for the yields of process heat.
NARVA delivers tubes to collectors manufacturer.
