Regenerative Thermal Oxidizers (RTO)

An installed regenerative thermal oxidizer unit

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.

Regenerative Thermal Oxidizers (RTO) are the technology of choice for most applications due to its high VOC destruction efficiency, low fuel use and long system life.
We are buying a new piece of process equipment. Do we have capacity in our existing oxidizer or can we make changes to achieve the needed capacity?

We can evaluate the existing oxidizer capacity and the requirements of the new process and determine the best approach to upgrade the oxidizer. This could include new heat exchanger media, a larger fan or possibly both. We would also evaluate things like the burner system and combustion chamber size to verify it can provide the required destruction levels. Some applications would be a good match for a VOC concentrator that can significantly concentrate (>10:1) airstreams currently exhausting to the oxidizer.

What does regenerative mean?

The term “regenerative” in regenerative thermal oxidizer is drawn from the type of ceramic media heat exchanger used in these systems. It is unique in that it captures heat from the exhausting, clean airstream during one cycle and releases the heat to the incoming, dirty airstream in the next cycle. The heat is captured (and released) from beds of ceramic media. The RTO incorporates switching valves to cycle the direction of the airflow through the RTO heat exchanger beds to enable regenerative heat recovery.

What is the operating temperature of a thermal oxidizer?

Typically 1400 F minimum up to 1550 F depending upon the VOC characteristics.

We are considering a refurbished regenerative thermal oxidizer (RTO) to reduce the capital investment for an planned expansion. What warranty is available for the equipment and individual parts, and also what system performance is available?

This is a common concern.  Will the buyer be left with only promises, or will Kono Kogs provide robust support after the purchase and commissioning of the oxidizer? We have never failed to meet our warranty in either parts or oxidizer performance. We have references that will attest to this in every business size- from start-up bootstrapping companies, to growing small and mid-size companies, to Fortune 500 companies. Our experienced staff can handle any technical or maintenance issue, both on-site, and via KONOConnect to ensure a successful project, now and into the future with our long-life refurbished oxidizers.

Our warranty rivals that of new equipment OEMs and we can even extend the period, if desired. How do we do that?  We offer only the best built systems from the best names in the industry. We also perform extensive sub-system and parts checkouts and replace faulty or questionable parts, many times with upgraded parts. Our goal is a flawless project- achieved with collaborative planning with our staff’s extensive oxidizer experience. We are honored that our customers are our best advocates. They affirm that we deliver what we promise- which has been true since day one of Kono Kogs.

Would an induced draft fan be a better choice than a forced draft fan?
