tri-element vacuum tube
Feature:
Kaidun Vacuum tubes assimilate the advanced 12 layers of spattering deposition Of trivalent element technology, high borosilicate glass, gradual change of ALN/AIN-SS/CU selective complex absorptive coating. And these make vacuum tubes have high performance of absorption and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380°C of idle sunning, performing a strong heating ability.
Specification:
1). Structure: all glass concentric dual tube geometer
2). Glass material: borosilicate glass
3). Absorption: >0.92
4). Emittance: <0.08 (80°C)
5). vacuum: <5*10-3 Pa
6). Stagnation >230 m2.°C/KW
7) average heat loss: <0.8w/ m2.°C
8). Lifetime >15years
