Ozone Destruct Units Overview: Volume 1
Ozone destruct units are often an overlooked part of many systems, receiving attention only when issues arise. Below are some common questions and recommended practices to help ensure your ozone destruct units operate effectively and avoid unexpected failures.
Q: How frequently should I replace the destruct media?
A common question in our industry, yet it lacks a straightforward answer. Destruct media replacement typically becomes necessary when ozone breakthrough is detected. However, in many systems, the off-gas is vented to a remote location, which often goes unchecked. As a result, when breakthrough does occur, it can quickly compromise the destruct blower, leading to premature failure.
Recommended Monitoring Practices:
- Locate and Monitor Discharge Points: Identify where the destructs discharge and conduct daily checks to ensure there is no ozone breakthrough.
- Install an Ambient Ozone Monitor: Position an ozone monitor at the discharge point and connect it to your alarm system for immediate alerts.
Q: When should I inspect the destruct media, and why is this necessary?
The gas passing through a destruct bed can carry deposits, particularly in saltwater applications, where salt-laden air may cause buildup. In down-flow units, salt buildup typically occurs at the top of the media bed, whereas in up-flow units, it collects in the bottom screen. Over time, these deposits can obstruct airflow and lead to gas discharge through the moisture trap overflow.
Maintenance Note:
Routine inspection of your destruct media can help prevent operational disruptions and maintain system integrity. If you are experiencing issues with your ozone destruct units or other components, please reach out with any questions.
