Regenerative Thermal Oxidizers (RTO)
A regenerative thermal oxidizer (RTO) is an air pollution control device that destroys VOCs and hazardous air pollutants (HAPs) in industrial exhaust air. By using regenerative heat recovery, it achieves high fuel efficiency, often operating with 95% heat recovery.

FAQs
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.
Regenerative thermal oxidizers (RTOs) typically have a 0.5 second to 1.0 second dwell time for most applications.
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.
How often ceramic media needs to be replaced depends on several factors such as whether there are any acids or particulates present in the airstream, VOC (volatile organic compound) concentration, RTO airflow, and the type of media in use. When not exposed to adverse operating conditions, ceramic media beds can have a life of 5-10 years. When adverse conditions are present, the media may need to be replaced more often. Contact our service department to schedule an inspection.
Yes, our RTOs are typically skid-mounted and pre-assembled to minimize field welding and on-site labor. This simplifies installation and helps reduce overall turnkey project costs.
