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.

Typically 1400° F minimum up to 1550° F depending upon the VOC characteristics. Read more in Operating Temperatures of Different Oxidizers.

Some signs of ceramic media plugging include inability to reach and/or maintain the RTO operating temperature, increased pressure pulse from the RTO back to the process, reduced airflow capacity through the RTO, increasing fuel consumption, tripping of pressure switches at the emission source or during poppet valve actuation, and more. Contact our service department to schedule an inspection.

The term “regenerative” in regenerative thermal oxidizer (RTO) is drawn from the type of ceramic media heat exchanger used in these systems. It is unique in that it captures heat from the exhausting, clean airstream during one cycle and releases the heat to the incoming, dirty airstream in the next cycle. The heat is captured (and released) from beds of ceramic media. The RTO incorporates switching valves to cycle the direction of the airflow through the RTO heat exchanger beds to enable regenerative heat recovery.

Feel free to check our RTO Inventory and get in contact with our sales and applications engineers to ensure that the system meets your needs. Quality-built refurbished regenerative thermal oxidizer (RTO) systems 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.
