Regenerative Thermal Oxidizers (RTO)

regenerative thermal oxidizer supplier offering new and refurbished equipment
New RTO Project?
Help With An Existing RTO?

A regenerative thermal oxidizer (RTO) is an air pollution control device that destroys VOCs and hazardous air pollutants (HAPs) in industrial exhaust air. By using regenerative heat recovery, it achieves high fuel efficiency, often operating with 95% heat recovery. As an RTO supplier, Kono Kogs helps facilities evaluate new custom-built and refurbished systems to find the right fit for their needs.

Are refurbished RTO systems available with the features I need?

Feel free to check our used RTO inventory and get in contact with our sales and applications engineers at sales@konokogs.com to ensure that the system meets your needs. Quality-built refurbished regenerative thermal oxidizer (RTO) systems from KKI offer a long service life, can save you up to 40% compared to new units, and come with performance and parts warranties comparable to those of new systems.

How often should combustion chambers be inspected?

Inspection frequency varies by system and operating conditions, but periodic inspection is important to detect refractory damage, burner issues, or thermal problems before they lead to system failure. We’re oxidizer experts so you don’t have to be - reach out to our team for guidance based on your specific process conditions.

What warranties and performance guarantees come with refurbished regenerative thermal oxidizers (RTOs) from Kono Kogs?

Kono Kogs stands behind every refurbished RTO with warranties that match or exceed those of new equipment OEMs. We have a proven track record of meeting warranty commitments for parts and system performance across a wide range of customers from startups to Fortune 500 companies. Our experienced team provides ongoing technical and maintenance support both on-site, and remotely via KONOConnect to ensure your system operates reliably over the long term.

To ensure quality, we use only top-tier components, conduct thorough inspections, and upgrade parts as needed. Our collaborative planning and extensive oxidizer expertise help deliver flawless projects that our customers trust and recommend.

What's the difference between a thermal oxidizer and an RTO?

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.

What are sources of inorganic plugging in an RTO?

Sources of plugging in ceramic media in an RTO can come from inorganic or organics contaminants including oils, fats, greases, paint solids, semi-conductor fabrication (hexamethyl disilzane; HMDS), VOCs containing silica or silicones, and siloxanes.
