Regenerative Thermal Oxidizers (RTO)

RCOs offer greater fuel economy, while recuperative units may be best for high VOC concentration airstreams (or an RTO can be considered). Contact KKI for guidance in choosing the right oxidizer for your application.

Using a bake-out feature can help prevent and remove organic compound buildup in the ceramic media, reducing the risk of plugging and maintaining efficient operation. A preheater or recirculatioin loop are also possible mitigation methods.

RTOs typically operate at 1500^o – 1600^o Fahrenheit depending upon the VOC characteristics. Thermocouples inside the chamber monitor temperature and adjust gas burner firing as needed. Adequate temperature is essential to ensure VOC destruction efficiency. In most cases a data log of chamber temperature is required for air quality compliance.

TOX typically have a 0.5 second to 1.0 second dwell time for most applications.

Yes, RTOs can be designed to match your specific exhaust airstream characteristics. They are typically optimized for airstreams with solvent concentrations in the 0–10% Lower Explosive Limit (LEL) range. For higher concentrations up to 25% LEL, additional features such as hot gas bypass systems may be needed to ensure safe and efficient operation.
