Product Description

FAQ:

1. Unique technology and production in the world?
Breaking through the prevalent issue of Ø137mm solar vacuum tube fractures, our product stands resilient where others falter. By conquering this notorious challenge, we deliver unmatched reliability and set a new standard of quality excellence in Ø137mm and Ø125mm solar vacuum tubes.

2. How about the performance of Ø137mm solar vacuum tube?
Our rigorous testing on an eight-story rooftop reveals impressive results: starting with 15°C water at 9 AM, it achieves a transformation to 55°C-69°C by 17:00 PM. By the next morning at 17:00 PM, the temperature escalates to a remarkable 85-95°C, showcasing our tubes' superior heat retention and efficiency.

3. How about the quality of Ø137mm solar vacuum tube?
Robust construction defines our tubes: a 3mm thick glass, fortified with silicone gaskets and metal brackets, safeguards against vibrations and transit challenges. Subjected to stringent tests, they withstand a free-falling steel ball of 30mm from 1.3 meters and support loads exceeding 100kg without cracking, ensuring unparalleled durability.
Additionally, we are participating in the settlement of national standards for large caliber vacuum tubes over Ø100mm

4. Are there any sales in national and international market for Ø137mm solar vacuum tube?
