Manufactured in 2004, this Adwest 25,000 Regenerative Thermal Oxidizer has a 25,000 scfm capacity. Previously treated emissions from a heatset web offset dryer. This RTO was running until June 2020, and it has been idle since. Ready to run, but could use some repairs to cladding/insulation.  The used Adwest Retox 25,000 has a two-can design with random packed ceramic media and a dual poppet (switching) valve configuration.

This RTO is in very good condition internally, though externally it is UV weathered, the insulation and cladding should be replaced, and it could use new paint. 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. The fuel injection feature has been a main-stay for Adwest RTO units, more than any other OEM, with significant fuel savings possible.
