China high efficiency solar collector tube/Tubing

outer tube diameter: 58/47mm
inner tube diameter: 47/37mm
length: 1.5-1.8m
absorptance:0.94~0.96
high quality with keenest
Our glass solar collector tube can start up fast and collects solar
energy fully, 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!
Our company currently products mainly for high high-borosilicate glass tube and solar energy vacuumed collecting-heat tubes. Solar energy vacuumed collecting-heat tubes using multiple domestic advanced automatic vacuum film-plating production line and high vacuum automatic exhaust station, and advanced
laser marking anti-counterfeiting technology, leading inspiratory/exhaust technology, it can produce
various specifications of the solar energy vacuumed collecting-heat tubes (ordinary pipe, three tenors vacuum tubes,violet gold vacuum tubes can
meet various climate and environmental conditions heating efficacy) 500 million pieces.
Heat collector tube advantages --
Technology advantage
