Manufacturers across South Dakota rely on CPI for regenerative thermal oxidizers (RTOs), catalytic oxidizers, and thermal oxidizers engineered for VOC compliance. Since 1969, CPI has designed and implemented oxidizer systems nationwide with thermal efficiencies above 97% and destruction removal efficiencies above 99%, backed by aftermarket support performed entirely by CPI's own team.
CPI designs and builds oxidizer systems — we are not a permitting firm, and every South Dakota facility's permit obligations depend on details specific to that site. Engaging an air permitting professional who is familiar not just with federal requirements, but with South Dakota's air permitting rules, is strongly recommended.
Here's how CPI fits into that process:
Whether your South Dakota project runs through an outside environmental consultant, an in-house EHS group, or your engineering team, CPI works alongside them, offering:

"The thing that always impresses me is they stand behind what they do and do the best they can — the systems they sell, the service they offer, the follow-up with the customer." — Director, Air Emissions Testing Firm
CPI's aftermarket service is performed by direct CPI employees — not third-party contractors — so South Dakota facilities get factory-trained technicians who know CPI equipment inside and out.

Yes. CPI designs and manufactures custom RTOs, catalytic oxidizers, and thermal oxidizers for South Dakota manufacturers, built on successful implementations throughout South Dakota and nationwide.
Yes — CPI oxidizer systems are installed and operating at South Dakota facilities, permitted and accepted by DANR. That in-state history means South Dakota regulators are already familiar with how CPI designs and documents its systems.
Most South Dakota facilities need a Permit to Construct; major sources also need a Title V Air Quality Operating Permit. Your permitting consultant, EHS team, or engineering group can confirm which applies to your project.
Yes. CPI services most makes and models of regenerative thermal oxidizers, catalytic oxidizers, and thermal oxidizers, not only the systems we built ourselves.
No. CPI is not a permitting firm. We recommend confirming your specific requirements with an environmental consultant, EHS resource, or engineering team - CPI's role is supplying the oxidizer information that process depends on.
Yes. CPI works closely with environmental consultants on BACT/MACT analysis and project support, backed by a proven track record of oxidizers already operating in South Dakota.
