Regenerative Thermal Oxidizers (RTO)

Hotspots typically result from damaged or missing insulation or compromised metal surfaces that allow heat to escape. KKI has experienced fabricators and insulators who can repair your oxidizer. This may involve replacing damaged metal to provide a secure base for reattaching insulation modules and restoring proper thermal protection.

A regenerative thermal oxidizer captures industrial exhaust streams containing VOCs and HAPs, then heats the air to a high enough temperature to oxidize those pollutants into carbon dioxide and water vapor. Like other thermal oxidizer systems, effective RTO performance depends on the right combination of time, temperature, and turbulence.

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.

In most cases, yes. But proper evaluation is recommended to establish that no potential catalyst poisons or masking agents are present in your airstream.

Yes, most RTO systems are equipped with a VFD on the main fan. VFDs are important for efficient operation, allowing for volume turn-down, improved energy savings, and idle-mode operation when full airflow isn’t needed.
