Product Description

Product Description

The vacuum tubes absorb solar radiation and transfer into heat, pass to the fin by the tube wall, and then transfer to the U pipe by the fin, U pipe absorbs heat then transfer to medium,cold medium continuously flow into inlet and heated by U pipe, then flow out from the outlet, so that obtain the heat of solar energy heating water.

1. Twin-glass vacuum tubes: reliable, efficient, high temperature resistant, anti-freezing.2. There is no water in the vacuum tube, the system will still work even the tube broken.3. U pipe, most efficient.4. Aluminum alloy manifold and bracket, corrosion resistance, easy to install. It's suitable for flat and sloping roof.5.Flexible Installation, installation angle from 0°to9o°,roof and wall hanging installation.6. High temperature resistant rock wool glass wool, high density, good thermal insulation properties.7. High quality copper manifold, its testing pressure is 1MPa.8. Eco and economical, improves the environment and save your fuel cost.


The solar radiation passes through the glass envelope of the vacuum tube and is projected onto the inner glass tube, and the glass inner tube is in close contact with the aluminum wing.

Company Profile

Since its establishment in 2002, Shandong Longguang Tianxu Solar Energy (hereinafter referred to as "Tianxu") has always engaged itself in the R&D, production, sales and service of high borosilicate glass tubes and new energy products including solar water heaters, solar vacuum tubes, solar heat collecting project, air source heat pump, photovoltaic products, etc. Tianxu has 10 sets of electric furnaces, 70 sets of solar vacuum tube production line and 3 sets of solar water heater production lines. The annual output has reached one million tons of high borosilicate glass, over 16 million solar vacuum tubes makes Tianxu the largest manufacturing base of high borosilicate glass tubes and solar vacuum tubes. In 2015, Tianxu established a joint venture company with Beijing Tsinghua Solar - the solar vacuum tube technology initiator in the world. The newly established company has the world's most advanced solar vacuum tube production lines.
