Durr MEGTEC Systems Clean Switch 25000 Regenerative Thermal Oxidizer (RTO)


This Regenerative Thermal Oxidizer (RTO) was well maintained and is in very good condition.  Maximum capacity of 25,000 scfm. This MEGTEC RTO was built in 2003 and was used to treat fumes from multiple heatset printing presses. The plant was shut down in early 2018 and the RTO was disassembled and moved from the site. This unit is available for immediate sale.   This unit has VOC entrapment for very high VOC destruction rates and hot-side bypass for high solvent loading applications.

This RTO was well maintained with annual PM inspections. Clean Switch RTOs are well built, highly reliable systems with long life expectancy.
