Regenerative Catalytic Oxidizers

Extensive catalyst application experience allows our engineers to select the best catalyst type, and pair it with an optimized ceramic media mix for long life, and for low fuel and electric use.

An RCO is essentially an RTO with a catalyst layer added. (See What is an RTO?).

Your operating permit will define a time (typically every 5 years), but a wise maintenance practice is to test annually as part of a preventive maintenance inspection.

Chemical, pharmaceutical, OSB (oriented strand board) press, particle board dryer, MDF (medium density fiberboard) dryer, plywood, paint spray booths;  and any application under 2% LFL is a good candidate.

Typical applications for catalytic oxidizers can range from ambient to very high process temperatures, mildly corrosive exhaust streams, and particulate free or well filtered airstreams with no catalyst-masking chemicals.

RCOs offer greater fuel economy, while recuperative units may be best for high VOC concentration airstreams (or an RTO can be considered). Contact KKI for guidance in choosing the right oxidizer for your application.

Up to 99% VOC destruction efficiency; and up to 97+% thermal efficiency.

Catalyst utilized in a regenerative catalytic oxidizer (RCO) allows chemical reactions to occur at lower temperatures (700-800F) than they occur in a thermal oxidizer (typical 1400-1450F) or an RTO (typical 1600F).

Perhaps. The retrofit typically involves catalyst somewhere in the media bed, allowing the unit to operate as Regenerative Catalytic Oxidizer (RCO).The result is reduced operating temperatures and energy savings. However, the conversion may be more complex or not possible if the unit is older, heavily customized, or in poor condition. Please contact KKI for a detailed review of the process.
