Product Description

FAQ:

1. Unique technology and production in the world?
The fragility and breakage of Ø137mm solar vacuum tubes have been a critical obstacle that many manufacturers shy away from, hindering their production of both Ø137mm and Ø125mm sizes. However, our innovative solutions not only conquer these challenges but also excel in meeting the apex of quality standards.

2. How about the performance of Ø137mm solar vacuum tube?
In our thorough rooftop trials on an eight-story building, with diurnal temperatures peaking at 12°C and nocturnal dips to 5°C, we injected water at 15°C by 9 AM. By 17:00 PM, the water temperature impressively varied between 55°C and 69°C. Astonishingly, the following morning at 17:00 PM, the hot water temperature soared to a remarkable 85-95°C.

3. How about the quality of Ø137mm solar vacuum tube?
Crafted with precision, each glass layer measures a robust 3mm in thickness, reinforced by silicone gaskets and metal brackets to safeguard against vibrations and the rigors of long-distance transit. Our tubes withstand the impact of a 30mm steel ball dropping from 1.3 meters unscathed and endure over 100kg of load without breakage.
Additionally, we are at the forefront of establishing national standards for large caliber vacuum tubes exceeding Ø100mm

4. Are there any sales in national and international market for Ø137mm solar vacuum tube?
Our solar vacuum tubes have garnered international acclaim for their superior quality. Over 10,000 units of Ø137mm and Ø125mm large-caliber vacuum tubes have been exported worldwide via sea and air, with meticulous packaging ensuring zero breakage. Our European shipments continue to arrive safely, reinforcing our commitment to excellence.
Since the advent of their extensive application in China since 2019, we have distributed over 100,000 Ø137mm and Ø125mm solar vacuum tubes to a broad spectrum of residential and commercial users across diverse Chinese territories. Presently, more than 25,000 users are relishing the luxuriant availability of solar-heated water.

5. What is capacity for one piece of Ø137mm solar vacuum tube?
It boasts a remarkable capacity of 19 liters of water per tube. In contrast, the common market diameter of 58mm solar tubes holds less than 3 liters each, showcasing the superior capacity of our product.

6. Please introduce the technology and technique?
The Ø137mm and Ø125mm tube thickness of 3mm demands cutting-edge technology and exceptional manufacturing expertise. The glass purity is paramount, ensuring optimal performance. Its expansive absorption area guarantees the highest hot water output efficiency.
