Vacuum Tube	Size (mm)	Φ581800 / Φ471500
	Tube (pcs)	40 / 50 / 60
	Glass	A highly efficient vacuum system can be achieved by utilizing a double layer of borosilicate 3.3 glass. This glass is known for its exceptional quality and durability. The incorporation of high vacuum technology ensures that the system operates at optimal levels, providing reliable performance and long-lasting functionality. The double layer design enhances the insulation capabilities, minimizing any heat transfer and reducing energy losses. This innovative solution guarantees a superior vacuum experience, making it an ideal choice for various scientific and industrial applications.
	Coating	The choice between single-target AL/AL-ALN(H) and three-target Cu/SS-ALN greatly depends on the specific requirements and objectives. Single-target AL/AL-ALN(H) is ideal when focusing on a specific target and achieving precise results. It offers a concentrated approach that ensures accurate performance. On the other hand, three-target Cu/SS-ALN provides a broader scope by targeting multiple objectives simultaneously. This approach is advantageous when dealing with complex systems or when multiple targets need to be addressed simultaneously. It is important to carefully consider the desired outcomes and resource availability when making the decision. Both options have their own merits and drawbacks, so a thorough evaluation is necessary to determine which approach aligns best with the project requirements.

Accessories	Silicon seals designed for anti-aging purposes, dustproof seals, and stainless screws are essential components for ensuring the longevity and functionality of various devices. These silicon seals play a crucial role in preventing the effects of aging, such as degradation and wear and tear, thereby maintaining the efficiency and performance of the devices they are applied to. By effectively sealing out dust, these seals also safeguard the internal mechanisms of the equipment from damage caused by contaminants. Furthermore, the use of stainless screws enhances the overall durability and stability of the devices, ensuring a secure and reliable construction. Whether it's in electronic devices, automotive parts, or industrial machinery, the incorporation of these anti-aging silicon seals, dustproof seals, and stainless screws is vital for prolonging the lifespan and effectiveness of the respective products.

Working Principle

The mechanism of a solar vacuum tube is simple. The tubes are directly plugged into the manifold tank, and as the sun's rays heat the cold water in the tubes, the hotter water naturally rises to the manifold tank due to the difference in specific gravity. In turn, the colder water automatically flows down to the glass vacuum tubes. This constant movement ensures that the cold water in the manifold tank is gradually heated.
In an active open-loop solar system, the hotter water in the manifold is pumped into a hot water storage tank, while the colder tank water is circulated back to the manifold collector for solar heating. This continuous circulation guarantees that the cold water in the system is always being heated, while the hot water is stored for later use.
Overall, the use of solar vacuum tubes is an efficient and eco-friendly way to harness the power of the sun for our daily water needs, and the simple mechanism behind it is easy to understand and maintain.
