CDU Rebuild Kit

Rebuild kit for CDU Ozone Destruct Units.  Kit includes replacement catalyst material, screens, and new gasket.


Rebuild kit for our CDU Ozone Destruct Unit. 

As your destruct unit ages the catalyst material will become contaminated with dust, hydrocarbons, NOx, and other potential contaminates.  This will cause lower ozone destruction efficiency over time.  We suggest replacing the catalyst material annually in critical applications to ensure continuous and reliable ozone destruction. 

Rebuild kit includes:

  • Sufficient catalyst material (Carulite 200) to replace all the catalyst in your CDU destruct unit 1 time

  • Replacement screens for the cap of the CDU destruct unit

  • Replacement gasket for the cap of the CDU destruct unit

Everything required for catalyst replacement is included.

Total time for catalyst replacement should be less than 30 minutes.



How long does the catalyst last?

  • Catalyst life will be dependent upon contaminates and overall use. We recommend replacing catalyst annually to ensure continuous and reliable ozone destruction.


What shortens the catalyst life?

  • Water condensing on the catalyst will damage the catalyst that water condenses on. This is why heaters and water traps are recommended on all applications where ozone is destroyed in moist air or ozone off-gas applications

  • Hydrocarbons, VOC’s, Sulfer compounds, Halogenated compounds, Heavy metals, Nox, and Silica will all poison the catalyst and shorten the life.

Is there a shelf life for the catalyst? Can we buy a rebuild kit and keep it on the shelf?

  • There is no shelf life for the catalyst. It will last indefinitely on the shelf. Store in cool, dry area in a closed container. Segregate from easy oxidizable materials.

Is the spent catalyst considered a hazardous material?

  • The catalyst is not a hazardous substance, however it should be handled with care. Protective equipment in handling including, safety glasses, and gloves should be used.

  • Disposal of the catalyst in a standard landfill is approved after verifying that it is not contaminated with hazardous substances through usage.


Do you offer repair/rebuild kits for other brands of destruct units?

  • Yes we do. The Carulite 200 material used for catalyst material is the same in most all catalytic ozone destruct units. We can provide this catalyst, screens, gaskets, heaters, water traps and every part you might need. Contact us for details.
