Our vacuum Solar collector tube can start up fast and collects solar energy fully, there is no need to wait and the water is available immediately, high level vacuum ensure operation under cold weather, and the unique super copper surface allowing lower reflection and minimal heat loss, the current products mainly include: diameter: 47/58mm, and the length is 1800mm, but we can also provide products as your request. Long time warranty for 15 years.
We are looking forward to establish business relationship with you!
Evacuated solar collector tubes introduction
We are a large enterprises specialized in the production of high borosilicate glass tube,rod and
solar energy vacuumed collecting-heat tubes. At present, our company has two set of high borosilicate whole electric furnaces ,
ten solar energy vacuumed collecting-heat tubes full automatic production line. It can produce high borosilicate solar glass tube of
20,800 tons ,glass rods of 20500MT and solar energy evacuated collecting-heat tubes 500 million pieces.
We had passed through the ISO9001:2000 international quality system authentication in 2009.
Specialization ensure us super quality
