All-glass evacuated solar collector tubes

for 15 years warranty
OEM is welcomed
glass material: high borosilicate 3.3 glass
high quality with high efficiency


Our solar collector 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!

Equipment advantage
Advanced technology inseparable from the advanced equipment, we know that effective
technical carrier craft and technology that can give full play to the best level, therefore,
we pay a huge sum of money to introduce the domestic and international advanced equipment,
and the largest domestic investment built automatic production line, this is definitely the best
quality pursuit of our examples.
Without the forming pull sealing machine, automatic coating machine, automatic sealer, online
continuous annealing line and continuous fine cut roast mouth. Specialized production
equipment such mechanization
Exclusive adopt touch no switch programmable automation control system, which can effectively
control process parameters, improve the vacuum, effectively control the membrane layer of
quality.
Coating tube production automatic detection monitoring system, exhaust microcomputer remote
communication automatic monitoring, to achieve a truly product quality microcomputer control
digitalization.
The world's advanced Optosol - Alpameter detector, can not only accurate measurement of tube absorbing coatings to attract
rate and emissivity measurement result, and may, according to the data processing, through
computer simulated sunlight, make the sun do anti-aging test the quality of absorbing coatings to continuous improvement, to optimize and
improve.
