Durr MEGTEC Systems MILLENNIUM 8000 Used Regenerative Thermal Oxidizer (RTO)


Regenerative Thermal Oxidizer (RTO) with a maximum capacity of 8,000 scfm (2,000 scfm minimum).  Built in 1998. Rebuilt by Kono Kogs in 2008.  In very good condition.  Previously treated emissions from a heat-set printing press until January 2018.  The unit has a puff capture feature (VOC entrapment) to eliminate visible emissions and provide a high VOC DRE. Also includes a hot side bypass system for high VOC concentration airstreams.

This MEGTEC 8,000 Regenerative Thermal Oxidizer was refurbished by Kono Kogs in 2008, and has since operated at very easy, low flow conditions. The RTO is an older model, but is in very good condition inside and out.

Ceramic media needs re-packing/replacement which is included in the as-is and refurbished option.
