1.Vacuum degree of interlayer is 5.2x10-4 which effectively reduced the heat loss and guarantee heat loss rate of 0.04-0.06, and ensure more 15 years service life.
2.Great transmission property (increase 5% transmission rate), possess self-cleaning function.
3.Apply metallic copper as bottom metal layer, which is super strong in absorbing and possess extra low heat loss, the heat loss rate is 50% lower than ordinary vacuum tubes, it can reach ULT≤0.5W/(m2·ºC)
4.Full automatic evacuated tube production line and advanced and strict testing process guarantee the entire quality stability.
5.The stainless steel aluminum nitride in the absorbing layer has high thermal stability, even the glass was melted, the coating will not fall off; using stainless steel ion to substitute aluminum, which make it has great withstanding performance of high temperature, aging, weakening and stagnation.
