The Principle and Characteristics of All Glass Vaccum Tube

Patent high-tech and attractive price High heat collection rate Good performance with high sunray absorption Energy saving

All-glass vacuum tube collector structure and characteristics

 Characteristics

1) Use of the nation granted patent invention---the sunlight selective absorption painting technology of magnetron sputtering aluminum gradient nitrogen by National Tsinghua University, with high-efficiency heat collection, low thermal damage,long life span.

2) Vacuum tubes are made of borosilicate glass 3.3 with high light transmittance, hot/cold-resistance, high impact-resistance, sable chemical reaction, and high mechanical strength.

3) The vacuum tube enjoys the structure of double-deck glass, laminated with the gas pressure achieved P ≤ 5X0.01Pa

4) Vacuum tube to be placed in the South, take advantage of tracking the sun by the natural characteristics, with an average thermal efficiency of 50% ..

 5) The seasonal changes effect less, for whenever appears the sun the heat can be collected effectively, and the system will be running perfectly throughout the year.
