Specification:

Suunny common gathering warm vacuum tube diameter 47mm, 58mm, 70mm. In length is 1.2 m/ 1.5m/ 1.6m/ 1.7m/ 1.8m/ 2.0m multiple graded AI-N/ AI specifications selective coating the entire structure of the coaxial double glass vacuum tube solar collector, three-cavity, the three executives interference coating. We look forward to solar industry colleagues to inspect and guide negotiations, and create a glorious industries.

1. Not bombing tube ( super antifreeze)
Because of using auto-annealing kiln system, the stress is less than 100 nm. Due to high temperature absorbs heat pipe technology , the tube has greatly enhanced the efficiency of the products.In rare sunlight layer coating material was quickly activated, within moments to create a large vacuum tube with water temperature, hot and cold water, rapid cycleMeanwhile vacuum tube directly from sunlight-absorbing surface and the reflected light-temperature dropped significantly, the formation cycle so as to further enhance the anti-freezing winter cold vacuum tube in the north.

2. High decalescence , low heat loss, this is particularly suitable for cold areas ( super-insulation)
Ceramic production techniques were gradually high temperature ceramic membrane selective absorption - using electron beam evaporation techniques suitable for high-temperature applications ( for the domestic solar water heater do a job with skill and ease Improved coating layer structure, the vacuum tube can bear temperature reaches 300 Celsius degree . A vacuum tube avoid long-term exposure to the film and aging, discoloration, attenuation performance, and long life. Compared with ordinary vacuum tube products with the high-temperature, high-efficiency, low-loss advantages of the same remarkable results in a frigid environment collector.

3 .Corrosion resistance and long service life ( long life)
Groove high standard borosilicate glass, linear expansion coefficient 3.3* 10-6 Celsius degree , in line with international ISO1776 anti-acid level, ISO695 alkali A2 level, excellent mechanical properties, hardness -- Mok' s 7.2.

4. Efficient all endothermic ( super-heat absorbing)
Germany OPT monitoring process monitoring, quality of the only solar-absorption more than.945, µ more than 0.05 hemisphere than fired. Mainly absorb solar light wavelength 0.35 um. In the same heat gain more water flow conditions; The other using the vacuum tube Diameter 58, the cross-section perimeter further heating, heating units larger.

5 . Hail resistance capacity
25mm diameter hail impacts damaged voltage 1Mpa, excellent mechanical properties
