Manufacturers across Colorado 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 Colorado 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 Colorado's air permitting rules, is strongly recommended.
Whether your Colorado project runs through an outside environmental consultant, an in-house EHS group, or your engineering team, CPI works alongside them, offering:

"CPI has scored very highly across the board on our projects — they've had the best combination of everything." — Project Manager, Engineering Design Firm (Food & Beverage)
CPI's aftermarket service is performed by direct CPI employees — not third-party contractors — so Colorado 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 Colorado manufacturers, built on successful implementations throughout Colorado and nationwide.
Yes — CPI oxidizer systems are installed and operating at Colorado facilities, permitted and accepted by CDPHE. That in-state history means Colorado regulators are already familiar with how CPI designs and documents its systems.
Possibly, since it applies specifically to VOC and related pollutant sources located near communities that score above the 80th percentile on Colorado EnviroScreen. Applicants use CDPHE's Environmental Justice Report Tool to check before submitting a permit application. Your permitting consultant, EHS team, or engineering group can confirm whether it 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 Colorado.
