This is new to us so can you please explain the technology and the process of installing an RTO?

How much time do you have? Lol. If this is entirely new to you it might be best for you to gather the key people on your team and let us invite you to an online webinar to provide you with some knowledge via a presentation we call, 'Oxidizer 101'.

What information do you need from us to begin the selection process?

We'd like a brief description of your process and what we are treating; including the exhaust volume, temperature, the VOC specs, and the amounts in pound per hour.

Please fill out this form.

How long does it take from the time we start until everything is complete?

Typically around six to eight months.

Do you have any idea about how much this is going to cost us?

It really depends on the size of the project, but we typically tell people, "you have at least a half-million dollar problem on your hands". Learn more about regenerative thermal oxidizers, including cost and much more.

How easy are these to maintain? Is there a lot of maintenance?

You get out of it what you put into it.  There are not a tremendous amount of moving parts. Plus, the lifeblood of the system for these is compressed air. You need a dedicated desiccant dryer for the air supply to the RTO with at least a dew point of -40° F.  Kono Kogs offers full preventive maintenance and emergency service in the event you have any apprehension about maintaining the system yourself.

Over 25 years of doing whatever is necessary to keep you running reliably.
