General Oxidizer Information


Regenerative Thermal Oxidizer (RTO). 35,000 scfm capacity (32,000 scfm capacity at 150F; upgradeable to 40,000 scfm).   Manufactured in 2000 and treated emissions from a paint spray booth. It was run for less than 2 years and has been idle since. Two-chamber design with random packed ceramic media and a dual poppet (switching) valve configuration.  In very good to excellent condition internally. Externally is UV weathered, and mechanical components will need a full refurbishing due to lack of use. Located at Kono Kogs facility and available for inspection.


Adwest Retox RTO systems are designed to provide one of the lowest utility costs (fuel & electric) of any leading oxidizer system. It is a simple RTO with over-sized beds to reduce pressure drop; evidenced by the 150 hp main fan motor for 35,000 scfm capacity. The fuel injection feature has been a main-stay for Adwest RTO units, more than any other OEM, with significant fuel savings possible.
