Regenerative Thermal Oxidizers (RTO)

The refractory lining insulates the combustion chamber and helps retain heat. If the refractory becomes cracked, worn, or damaged, heat can escape from the chamber, forcing the burner to fire more frequently to maintain temperature. Over time, this increases fuel consumption and can create hot spots that shorten equipment life.

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.

Yes, most RTO systems are equipped with a VFD on the main fan. VFDs are important for efficient operation, allowing for volume turn-down, improved energy savings, and idle-mode operation when full airflow isn’t needed.

Induced draft fans are often preferred when handling particulates and solvents with high boiling points, as these solvents can condense and build up on forced draft fan wheels, causing maintenance issues and reduced efficiency.

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.
