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

"CPI is best in the world at making RTOs that last a long time and are of good quality." — Senior Consultant, Air Quality Consulting Firm
CPI's aftermarket service is performed by direct CPI employees — not third-party contractors — so Tennessee 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 Tennessee manufacturers, built on successful implementations throughout Tennessee and nationwide.
Yes — CPI oxidizer systems are installed and operating at Tennessee facilities, permitted and accepted by the applicable agency. That in-state history means Tennessee regulators are already familiar with how CPI designs and documents its systems.
It depends on location. Most of Tennessee applies through TDEC's Division of Air Pollution Control, but facilities in Davidson (Nashville), Hamilton (Chattanooga), Knox (Knoxville), or Shelby (Memphis) County go through those counties' own air programs instead. Your permitting consultant, EHS team, or engineering group can confirm which authority applies to your site.
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 Tennessee.
