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
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.
We can evaluate your current oxidizer’s capacity alongside the new process requirements to recommend the best upgrade approach. Options may include adding new heat exchanger media, installing a larger fan, or modifying the burner and combustion chamber to meet destruction needs. For some cases, using a VOC concentrator to reduce pollutant levels before the oxidizer can be an effective solution. Please note that existing equipment may not be sufficient, even with changes or upgrades.
Kono Kogs stands behind every refurbished RTO with warranties that match or exceed those of new equipment OEMs. We have a proven track record of meeting warranty commitments for parts and system performance across a wide range of customers from startups to Fortune 500 companies. Our experienced team provides ongoing technical and maintenance support both on-site, and remotely via KONOConnect to ensure your system operates reliably over the long term.
To ensure quality, we use only top-tier components, conduct thorough inspections, and upgrade parts as needed. Our collaborative planning and extensive oxidizer expertise help deliver flawless projects that our customers trust and recommend.
RTOs typically operate at 1500o – 1600o 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.
Inspection frequency varies by system and operating conditions, but periodic inspection is important to detect refractory damage, burner issues, or thermal problems before they lead to system failure. We’re oxidizer experts so you don’t have to be - reach out to our team for guidance based on your specific process conditions.
