IN USA reduces ozone to safe levels (Product Showcase)
The reactivity and oxidative power of ozone has resulted in a wide variety of industrial applications such as semiconductor wafer manufacturing and ultra-pure water treatment. However, excess ozone generated in these applications can reach concentrations of 20% by weight (120 000 ppmv). To counter this dangerous build-up, IN USA has introduced the O3-CAT range of ozone catalysis systems to decompose the highly reactive molecule to oxygen at safer levels (i.e. below 0.1 ppmv). The O3-CAT system uses chemical adsorption at the solid surface of a catalyst bed, which decomposes ozone in an exothermic reaction to form oxygen. The O3-CAT design takes into account the temperature, flow and humidity levels of the sample (see ).
