Regenerative Thermal Oxidizer Manufacturer Serving Maryland

Manufacturers across Maryland 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.

Maryland Air Permitting: How CPI Supports Your Compliance Process

CPI designs and builds oxidizer systems — we are not a permitting firm, and every Maryland 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 Maryland'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 Maryland regulators already recognize. CPI oxidizer systems are permitted and operating across Maryland, helping our customers stay in compliance with their permit obligations.

Frequently Asked Questions

Can CPI manufacture a regenerative thermal oxidizer for a Maryland facility?

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

Are there CPI oxidizers already running in Maryland today?

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

Does the D.C.–Baltimore nonattainment area affect my facility's VOC requirements?

Possibly, since it brings stricter RACT-based VOC control obligations across much of the state. Whether — and how — this applies to your facility is best confirmed with your permitting consultant, EHS team, or engineering group.

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 MDE 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 Maryland 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 Maryland.
