Regenerative Thermal Oxidizers (RTO)

The burner provides the heat required to raise the gas stream to the oxidation temperature needed to destroy VOCs.

Catalyst utilized in a regenerative catalytic oxidizer (RCO) allows chemical reactions to occur at lower temperatures (700-800F) than they occur in a thermal oxidizer (typical 1400-1450F) or an RTO (typical 1600F).

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, 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.

Clean process airstreams with high air flow and low VOC content (<10% LFL) are ideal applications. Higher VOC concentrations can be tolerated, as well as organic/inorganic particulates with proper planning and design, and possibly filters. See our case studies for a sample of possible applications.
