ozone destructor


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 destructor device uses Carulite 200. It is not consumed by the ozone and is a safe material that is not considered hazardous waste.

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. 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.

  • AOD 1500D
  • AOD 2001D
  • AOD 2002D
  • AOD 2003D

These are inexpensive ozone destruct units, made for removing high concentrations of ozone efficiently. The stainless steel construction ensures it can covert any concentration of ozone into harmless oxygen.

  • 99.9% Efficient
  • Stainless Steel Construction
  • Low-pressure drop (up to 0.02 bar)
  • O2 & minimal heat is the only by-products
  • Quick & easy hook-up

The AOD destructors are compact ozone destruct devices compatible with moisture-saturated ozone gas streams (except AOD2002).  A heater band is used in conjunction with piping configurations, in order to keep water vapors from condensing on the destruct media. The device must be mounted in the upright position to maintain efficient operation and moisture removal. For very wet air (contact tank off-gas), we recommend using a water trap to remove bulk moisture.
