RTOs use a series of ceramic heat exchangers to capture and reuse heat generated during the oxidation process. This makes them highly energy-efficient. The process begins with the contaminated air entering the oxidizer, where it is preheated by the ceramic media. The air then moves to a combustion chamber, where it is heated further to the required temperature for oxidation. The clean, heated air then passes through another set of ceramic media, transferring its heat before being released into the atmosphere.
