Proper maintenance is key to keeping your ozone destruct unit functioning at peak performance. Over time, even the best equipment can see a decline in efficiency due to contaminant buildup. The CDU-300 Rebuild Kit offers a simple, effective solution to restore your CDU Ozone Destruct Unit to full operational condition—ensuring reliable ozone destruction for years to come.
Why Rebuild?
The catalyst material inside your CDU-300 ozone destruct unit—Carulite 200—plays a critical role in breaking down ozone gas safely. As your unit ages, this catalyst can become fouled by dust, NOx, hydrocarbons, and other airborne contaminants. This degradation reduces destruction efficiency and can compromise system performance in sensitive applications.
We recommend annual replacement of catalyst material in critical installations to maintain high-efficiency ozone destruction and avoid costly downtime.
What’s Included in the CDU-300 Rebuild Kit?
Our rebuild kit contains everything required to perform a full catalyst replacement quickly and easily:
- Carulite 200 Catalyst – 5 lbs
Sufficient to replace all the catalyst in a single CDU-300 unit. - 2 Replacement Screens
Ensures proper flow distribution and prevents catalyst dust escape. - 1 Gasket
Custom-fit viton gasket for a reliable and leak-free seal.
With all components included, you can complete the rebuild in under 30 minutes.
Step-by-Step: CDU Gasket Replacement Guide
- Position the Gasket:
Place the square viton gasket on the round CDU-300 lid, aligning holes. - Insert Bolts:
Slide bolts through the lid and gasket (bolt heads on the lid side). - Align and Attach:
Flip the lid/gasket assembly, align with the destruct cylinder holes. - Secure Fasteners:
Add lock washers and nuts, finger-tighten all before final tightening. - Tighten Evenly:
Use a cross-pattern (e.g., 8-4-7-5) to tighten all bolts securely. - Trim Excess Gasket:
Use a box cutter or knife to remove excess gasket material for a clean finish.
Frequently Asked Questions
Q: How long does the catalyst last?
A: It depends on exposure and use. For optimal performance, replace annually in critical applications.
Q: What shortens catalyst life?
A: Common catalyst poisons include water condensation, hydrocarbons, sulfur and halogenated compounds, NOx, heavy metals, and silica. Protect your unit with heaters and water traps when used in moist environments.
Q: Can the catalyst be stored long term?
A: Yes, Carulite 200 has no shelf life if stored in a cool, dry area in a sealed container.
Q: Is spent catalyst hazardous?
A: Not typically. However, wear gloves and eye protection when handling. Dispose in landfill only after confirming it is free from hazardous contaminants.
Q: Do you offer kits for other destruct units?
A: Absolutely! We provide Carulite 200, gaskets, screens, heaters, and more for many brands. Contact us to find the right parts for your system.
