Regenerative Thermal Oxidizer Manufacturer Serving Iowa

Manufacturers across Iowa 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.

Iowa Air Permitting: How CPI Supports Your Compliance Process

CPI designs and builds oxidizer systems — we are not a permitting firm, and every Iowa 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 Iowa's air permitting rules, is strongly recommended.

Here's how CPI fits into that process:

  1. Technical data your permit application will need. Emission rates, destruction/removal efficiency, stack parameters, fuel usage, and control technology specifications, delivered as part of every proposal.
  2. A design matched to your compliance target. Our applications engineering team coordinates with the parties responsible for your permitting so the oxidizer is sized to meet your permit's destruction efficiency and reporting requirements from day one.
  3. Ongoing support once you're operating. Equipment performance data for emissions reporting or agency inspections, whenever your compliance team needs it.
  4. A track record Iowa regulators already recognize. CPI oxidizer systems are permitted and operating across Iowa, helping our customers stay in compliance with their permit obligations.

Frequently Asked Questions

Can CPI manufacture a regenerative thermal oxidizer for an Iowa facility?

Yes. CPI designs and manufactures custom RTOs, catalytic oxidizers, and thermal oxidizers for Iowa manufacturers, built on successful implementations throughout Iowa and nationwide.

Are there CPI oxidizers already running in Iowa today?

Yes — CPI oxidizer systems are installed and operating at Iowa facilities, permitted and accepted by Iowa DNR. That in-state history means Iowa regulators are already familiar with how CPI designs and documents its systems.

Could my facility qualify for a Permit by Rule instead of a full construction permit?

Possibly, if your source category and emissions fall within Iowa DNR's defined criteria. Your permitting consultant, EHS team, or engineering group can confirm whether that streamlined path applies to your project.

Will CPI service equipment it didn't originally manufacture?

Yes. CPI services most makes and models of regenerative thermal oxidizers, catalytic oxidizers, and thermal oxidizers, not only the systems we built ourselves.

Does CPI manage Iowa DNR permitting on our behalf?

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.

Is CPI a resource for environmental consultants working on Iowa projects?

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 Iowa.
