Regenerative Thermal Oxidizers (RTO)

We can evaluate your current oxidizer’s capacity alongside the new process requirements to recommend the best upgrade approach. Options may include adding new heat exchanger media, installing a larger fan, or modifying the burner and combustion chamber to meet destruction needs. For some cases, using a VOC concentrator to reduce pollutant levels before the oxidizer can be an effective solution. Please note that existing equipment may not be sufficient, even with changes or upgrades.

TOX typically have a 0.5 second to 1.0 second dwell time for most applications.

An RTO is a type of thermal oxidizer that uses ceramic media beds to recover and reuse heat. Conventional direct-fired and recuperative thermal oxidizers use no primary heat exchanger or a metallic heat exchanger instead. Learn more about thermal oxidizers vs. RTOs.

Clean process airstreams with high air flow and low VOC content (<10% LFL) are ideal applications. Higher VOC concentrations can be tolerated, as well as organic/inorganic particulates with proper planning and design, and possibly filters. See our case studies for a sample of possible applications.

There are two main types of ceramic media. Structured ceramic media is typically block-shaped, with ceramic materials configured in a geometric design. It is often placed in several layers. The other type of ceramic media is random-packed ceramic saddles. These smaller, U-shaped (also called saddle-shaped) ceramic pieces are also availiable in different sizes and are spread and leveled evenly across the media bed. Kono Kogs also offers custom media configurations, such as a hybrid media bed, to best fit the heat transfer and particulate requirements of each process and unit.
