Article:【Purging Light doesn't produce ozone by way of UV irradiation
Date:2013/07/26

 

Purging Light is use of UV germicidal lamp wavelength which is 253.7nm--The range is still a short-wavelength, so the probability of UV penetrating quartz glass tube is not far from wavelengh 185nm.

Due to the usage of UV lamp on the market quite extensive, so ozone isn't necessarily applied to all uses.
Therefore, add to "titanium" elements in the quartz glass, above the 200nm UV quartz glass isolated inside, making the most of the ozone is blocked inside the tube.

But illumination of UV can still penetrate quartz glass tube, which reached sterilization effect. It does not produce ozone problem.
