Regenerative Thermal Oxidizers (RTOs)

Regenerative Thermal Oxidizers (RTOs) are advanced air pollution control systems designed to destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and industrial odors generated during manufacturing processes. Widely recognized for their high thermal efficiency and reliability, RTOs help facilities meet strict environmental regulations while minimizing fuel consumption and operating costs.

​

How RTOs Work

​

RTO systems use high temperatures—typically between 1,400°F and 1,800°F—to oxidize airborne contaminants and convert them into harmless byproducts such as carbon dioxide and water vapor. The system captures and reuses heat through ceramic media beds, allowing incoming process air to be preheated before entering the combustion chamber. This regenerative heat recovery process significantly improves energy efficiency and reduces natural gas usage compared to other thermal oxidation technologies.

Most RTOs operate using multiple chambers that alternate airflow direction in cycles, ensuring continuous operation and optimal heat transfer. Depending on the application, RTOs can achieve destruction efficiencies greater than 99%.

​

Industries Served

​

RTO technology is used across a wide range of industries where VOC emissions, solvent vapors, or process odors must be controlled, including:

• Chemical processing

• Paint and coating operations

• Printing and packaging

• Automotive manufacturing

• Pharmaceutical production

• Food and beverage processing

• Oil and gas operations

• Wood products and furniture manufacturing

• Semiconductor and electronics manufacturing

• Cannabis and hemp processing facilities

RTO systems are highly customizable and can be engineered to handle varying airflow volumes, contaminant concentrations, and process conditions, making them a proven solution for industrial emissions control applications.
