What Is a Regenerative Thermal Oxidizer (RTO)?
A Regenerative Thermal Oxidizer is a core component in modern waste gas treatment equipment, designed to eliminate volatile organic compounds (VOCs) and odorous gases through high-temperature oxidation (800–1000 °C).
By recovering heat via ceramic media, the RTO achieves > 95 % thermal efficiency while destroying up to 99 % of VOCs — making it one of the most cost-effective air pollution control equipment options available.

How an RTO Works
- Preheating Stage – Contaminated air enters a ceramic heat-exchange bed that recovers heat from the previous cycle.
- Combustion Stage – The air is heated in the oxidation chamber, converting VOCs into CO₂ and H₂O.
- Heat Recovery Stage – Clean, hot air passes through another bed to store energy for the next cycle.
- Flow Reversal – Automatic valves switch airflow to maintain temperature balance and maximize thermal efficiency.
