Either end will function as the inlet or outlet. The exit of the AOD can be left open to the atmosphere or piped to an outside area, away from personnel. The AOD is designed to have a maximum of 0.01 ppm ozone concentration at its exit when operated at its rated flow or below. Be sure that the ozone flow rate does not exceed the specifications for the unit. If the flow rate is too high, complete ozone destruction will not take place.
In the event that the catalyst becomes wet, such as when process water accidentally flows into the unit or water vapor condenses on the catalyst, the catalyst should be replaced. The ozone destruction efficiency might be reduced due to the possible contamination of the moisture and/ or water.
In the event the desiccant inside of the ozone destruct unit requires replacement, a new desiccant can be purchased from Absolute Ozone. By removing the fitting(s) from one end of the product, the old desiccant can then be poured out and replaced with new media.
