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 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'.

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.
