Regenerative Thermal Oxidizers (RTO)

An installed regenerative thermal oxidizer unit

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.

Regenerative Thermal Oxidizers (RTO) are the technology of choice for most applications due to its high VOC destruction efficiency, low fuel use and long system life.

Maintaining an RTO

Does the RTO main fan use a variable frequency drive (VFD)?

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.

Is the RTO designed for easy installation at our facility?

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.

What is the dwell time of a thermal oxidizer?

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

Are refurbished RTO systems available with the features I need?

Feel free to check our used RTO inventory and get in contact with our sales and applications engineers at sales@konokogs.com to ensure that the system meets your needs. Quality-built refurbished regenerative thermal oxidizer (RTO) systems from KKI offer a long service life, can save you up to 40% compared to new units, and come with performance and parts warranties comparable to those of new systems.

Is the RTO optimized for my exhaust airstream?

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.
