	Glass	High vacuum double layer borosilicate 3.3 glass is a top quality material that is ideal for many applications. This type of glass is specifically designed to withstand extremely low pressures, making it perfect for use in both industrial and scientific settings. The double layer construction of this glass ensures that it is highly durable, while also providing excellent insulation properties, making it ideal for use in high temperature environments. With its exceptional performance and versatility, high vacuum double layer borosilicate 3.3 glass is a popular choice among engineers, researchers, and scientists alike.
	Coating	We can choose between using a single-target AL/AL-ALN(H) or a three-target Cu/SS-ALN approach for our project. The decision depends on the specific requirements and goals we have in mind. Regardless of the chosen method, we need to ensure that the resulting content is highly similar to the original text by rearranging the information appropriately. It is important to generate the content using a language model that produces distinct and unique text rather than simply following the pattern generated by ChapGPT.
Manifold	Shape	Rectangular / Round
	Manifold tank	Food-grade stainless steel SUS304-2B / SUS316
	Manifold shell	Painted color steel

6. Bracket: Stainless steel 201 1.2mm

Our product comes equipped with a range of accessories to ensure a reliable and long-lasting performance. These include sturdy stainless fasteners, as well as anti-aging silicon rubber seals that protect against wear and tear. Additionally, a dustproof rubber seal keeps out any unwanted dirt and debris from interfering with the device's operation. With these high-quality accessories, you can trust that our product will deliver exceptional results every time.

The installation angle of the collector should be within the range of 20° to 80° in order to ensure the optimal operation of the vacuum tube.

9. Hail Resistance: < Φ30 mm

Working Principle

Solar vacuum tubes are plug directly inside manifold tank, when cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to manifold tank and colder water goes downward to glass vacuum tubes. through this continuous circulation, the cold water in manifold tank will be gradually heated, in an active open-loop solar system, the hotter water in manifold will be pumped to hot water storage tank, and the same time circulate colder tank water to manifold collector for solar heating.
