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

"They do a good job keeping the focus on the customer. From that respect, they're world class as far as operations go." — Director, Air Emissions Testing Firm
CPI's aftermarket service is performed by direct CPI employees — not third-party contractors — so Wisconsin 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 Wisconsin manufacturers, built on successful implementations throughout Wisconsin and nationwide.
Yes — CPI oxidizer systems are installed and operating at Wisconsin facilities, permitted and accepted by the DNR. That in-state history means Wisconsin regulators are already familiar with how CPI designs and documents its systems.
Possibly. Wisconsin offers a Registration Permit for lower-emitting facilities and industry-specific General Permits for certain source types, as streamlined alternatives to a full source-specific construction and operation permit. Whether your facility qualifies depends on site-specific factors your permitting consultant, EHS team, or engineering group can evaluate.
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 Wisconsin.
