ozone generators (3559-og)

overview of ozone generators (3559-og)

— ozone generators are used to produce ozone for cleaning air or remove smoke odors in unoccupied rooms. these ozone generators can produce over 3 g of ozone per hour. ozone often forms in nature under conditions where o2 will not react. temperature and humidity play a large role in how much ozone is being produced using traditional generation methods such as corona discharge and ultraviolet light. old generation methods will produce less than 50% its nominal capacity if operated with humid ambient air than when it operates in very dry air. new generators using electrolytic methods can achieve higher purity and dissolution through using water molecules as the source of ozone production. because of the high reactivity of ozone, only a few materials may be used like stainless steel (quality 316l), titanium, aluminium (as long as no moisture is present), glass, polytetrafluorethylene (ptfe - aka teflon®), or polyvinylidene fluoride (pvdf aka kynar®) . viton® may be used with the restriction of constant mechanical forces and absence of humidity (humidity limitations apply depending on the formulation). embrittlement or shrinkage is the common mode of failure of elastomers with exposure to ozone. ozone cracking is the common mode of failure of elastomer seals like o-rings. silicone rubbers are usually adequate for use as gaskets in ozone concentrations below 1 wt%, such as in equipment for accelerated aging of rubber samples.
