Regenerative Thermal Oxidation

Supplier: Clean TeQ Limited

Regenerative Thermal Oxidation is designed for applications where combustible volatile organics or odours are present in the gas stream.


Clean TeQ partners with Adwest, USA for the design, manufacture and installation of the RETOX® range of RTO’s for our region. The RETOX® unit consists of two ceramic catalyst beds.

An independent gas train with a burner is used for pre-heating the bed or to inject gas into the process gas stream to maintain the temperature within the combustion beds.
