The purpose of the ozone destruct is to convert ambient ozone gas into harmless oxygen before releasing it into the atmosphere.

The AOD series Ozone Destruct Unit utilizes a thermal-catalytic method to remove excess ozone. The catalyst is a transition metal manganese dioxide/copper oxide material. It is not consumed by the ozone and acts as a true catalyst.

Ozone off-gas can be treated with an ozone destructor, which converts ozone into oxygen rapidly and without emitting any toxic gases, such as carbon monoxide or carbon dioxide. All ozone destructors are complete with catalytic materials and quick coupling.

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. Any of the AOD series can be temporarily recharged by placing the product vertically in an oven or similar for 3 hours at 350 degrees F. 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. Be sure to reseal the removed fitting(s) with Teflon tape with Teflon paste on top of the Teflon tape to prevent any ozone from escaping by the threads when in use.
