The quartz tube's 99.9% of composition is silica, so its advantages are: strong rigidity, high heating proof, low expansion coefficient, thermal shock resistance, stability of chemical, and electrical insulation; High efficiency: adopt narrow gap discharge which is 0.5mm,so it has high rate of ozone convertibility with low noise; Low power consumption: The power consumption is 6-10kw.h.kgO3 due to adopt high voltage and frequency discharge; High voltage proof: Reaction tube working voltage only is 1/5 of its breakdown voltage, so it has high dielectric constant; Excellent quality: Dielectric material adopt high purity silica quartz and formed by high temperature, so it has high accurate and discharge flatness,316L stainless steel for internal electrode and fixings, Teflon for gas nozzles, sealing by anti corrosion high purity fluorine rubber ,external adopts latest sun halo heating dissipation technology which has effectively heating dissipation, and ozone reduced less than <1/10 for long time operating, and also it has long service life which will be 12000 hours.
