FAQ
1. Unique technology and production in the world?The breakage of Ø137mm solar vacuum tubes is a significant problem faced by many manufacturers and is one of the main reasons for their reluctance in producing Ø137mm and Ø125mm. our products not only overcome this challenge but also meet the highest quality standards.
2. How about the performance of Ø137mm solar vacuum tube?
Based on our experiments on the rooftop of an eight-story building, with daytime temperatures reaching 12°C and night temperatures dropping to 5°C, it is observed that when 15°C water was injected at 9 AM, the water temperature ranged from 55°C to 69°C at 17:00 PM. The following morning at 17:00 PM, the temperature of the hot water reached 85-95°C.
3. How about the quality of Ø137mm solar vacuum tube?
Each layer of glass is 3mm thickness, and there are silicone gaskets and metal brackets between inner and outer tube to prevent any damage due to vibrations or long distance transportation. Our tubes can withstand a steel ball with a diameter of 30mm falling freely from a height of 1.3 meters without any damage. Furthermore, the tubes can bear a load of over 100kg without any breakage.
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?
we take great pride in the quality of our solar vacuum tubes, Over 10,000 pieces of Ø137mm and Ø125mm large-caliber vacuum tubes have been exported worldwide by sea and by air safely. And we have shipped numerous times to Europe with careful packaging and zero instances of breakage.
Since its widespread application in 2019 in China, we have supplied over 100,000 Ø137mm and Ø125mm solar vacuum tubes to residential and commercial users in numerous areas across China. Over 25,000 users are currently enjoying an abundant supply of solar heated water
5. What is capacity for one piece of Ø137mm solar vacuum tube?
Capacity 19 liters of water. the diameter of the solar tube on the market is generally 58mm, each tube can hold less than 3 liters of water.
6. Please introduce the technology and technique?
The thickness of Ø137mm and Ø125mm tube is 3mm, which requests very high technology and manufacturing ability. And the purity of the glass also needs very high. Because of its large absorption area, the hot water output effect is the largest.
