vacuum tube production

After the Group's new vacuum tube titanium coating has proven itself on the Chinese market for the past year, Linuo Solar Thermal is thinking about introducing the product also on international markets. One of the biggest manufacturers of vacuum tubes in China has so far used an aluminium-based coating for all its products. The new coating of the Sunrain group - presented at the company´s 10-year anniversary in December 2010 – is said to be based on titanium as well.

Gujarat Borosil is the only solar glass manufacturing company in India with a furnace to manufacture end-to-end low iron patterned solar glass. In 2008, the company was to launch the first vacuum tube collector with glass tubes from its own production, to be sold under the brand name Borosolar (see news: http://www.solarthermalworld.org/node/276).  However, after being questioned about the issue, Borosil has now confirmed that it has never really started the serial production of its glass tubes for vacuum tube collectors. The company rather imported some tubes and sold collectors under its brand.
