2018 hot sales 58mm*1800mm solar evacuated vacuum tube

BTE Solar successfully developed the innovative advanced solar selective coatings in commercial scale, which achieve the highest thermal efficiency and good thermal stability, Solar selective coatings absorb more solar radiation while simultaneously suppressing the thermal emittance loss from coating surfaces. They vary mainly in their optical property and thermal stability. High level vacuum operation under cold weather.

2018 hot sales 58mm*1800mm solar evacuated vacuum tube

Voordelen::

1.Vacuum degree of interlayer is 5.2×10-4 which effectively reduced the heat loss and guarantee heat loss rate of 0.04-0.06, and ensure more 15 years service life.

2.Great transmission property (increase 5% transmission rate), possess self-cleaning function.

3.Apply metallic copper as bottom metal layer, which is super strong in absorbing and possess extra low heat loss, the heat loss rate is 50% lower than ordinary vacuum tubes, it can reach ULT≤0.5W/(m2·℃)

4.Full automatic evacuated tube production line and advanced and strict testing process guarantee the entire quality stability.

5.The stainless steel aluminum nitride in the absorbing layer has high thermal stability, even the glass was melted, the coating will not fall off; using stainless steel ion to substitute aluminum, which make it has great withstanding performance of high temperature, aging, weakening and stagnation.

6.Patent technology developed by Himin autonomously has break the limitation of graded coating, and enable its working temperature from -400to 400.

BTE Solar Co.,Ltd (BTE) is one of the leading manufacturer of solar hot water systems and photovoltaic system in China and around the world. With many years’ experiences and Research, BTE team has developed different kinds of solar collectors for different working temperature and circumstance. The solar thermal products including Vacuum tubes, Flat panel collector(High /low temperature), U pipe and Heat pipe collector, Linear concentrating collector, Steam Collector, Solar Water Heater and commercial system. The solar photovoltaic products including solar panels, solar lamps, power generating system and solar pumps. BTE automatic production line and strict quality management system can supply you high quality & long working life products.

The board of chairman Mr. Rongtao,Han is one totally technical guy, he has been do the research of solar key technology from year 2000,With his good technical background and ten years research, BTE founded in 2009.

Nu,BTE and Aoxin Holdings cooperated developed innovative industry integrated model and successfully build Hebei Aochang Industrial Park, Henan Xuchang Industrial Park, Shandong Jining Industrial Park, Total investment more than USD 20,000,000. The Second production base of BTE which located in Hebei Aochang Industrial Park has been finished. On the base of professional technology experiences and cooperation with researching institutes and universities, BTE has developed high weather-proof selective absorbing film from full-automatic magnetron sputtering production line. Averagely 1.5min/p can delivery your order in short time. The quick measuring instrument from Germany can do function test on production line which ensure each absorber plate meet our high quality requirements.

In 2014, BTE successfully developed the new flat panel collector with “Bonding” technologie. Its efficiency is 10% higher than normal blue film collector.

In addition, BTE is the core member of Solar Cooling Equipment Joint Research Center and supply heat collecting design for solar cooling system.

Nu, BTE not only supply energy saving products to global market, we also supply different energy saving solutions to realize your “Micro-Emission” vereisten.
