Extend the life of your current RTO with increased reliability and performance!

Regenerative thermal oxidizers typically have a heat recovery efficiency of 95%. This technology has the lowest operating cost of all thermal oxidizer systems – not to mention the longest service life and highest reliability.
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 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 remote monitoring 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 proper planning and 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.

We have hot spots on the outside of our RTO. Can you fix this?

Yes we have a team of experienced fabricators and insulators we can bring in to repair your oxidizer. Damaged metal may have to be replaced to ensure a secure surface is available to weld the insulation modules to.

Can we install catalyst in our RTO?

In most cases, yes. But proper evaluation is recommended to establish that no potential catalyst poisons or masking agents are present in your airstream.

We changed our process to be more water based and less solvent based and now my oxidizer is burning a lot more gas. Is there anything we can do to reduce the amount of gas used?

Yes, we can evaluate the heat exchanger whether it be metal (recuperative) or ceramic media (regenerative) and determine whether it can be upgraded to a more efficient type. Or maybe catalyst could be added in this case. In some cases it may be better to replace the current oxidizer with something more efficient. In that case we can look at our inventory and determine whether we have something that will provide better gas efficiency. If not, we can provide a custom system designed specifically for your needs.

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.
