The CMM Group has customized, manufactured, and implemented Regenerative Thermal Oxidizers (RTO) for companies around the world who need of efficient, effective and affordable pollution control and volatile organic compound (VOC) abatement. RTOs from The CMM Group are built to give you the highest destruction efficiency at the lowest cost.

We manufacture each regenerative thermal oxidizer to your unique needs, exhaust streams, and design requirements. Further, we will discover, recommend, and implement energy recovery solutions if needed to drive down operating costs and increase efficiency.

What is a Regenerative Thermal Oxidizer?

Regenerative Thermal Oxidizers are manufactured to destroy volatile organic compounds and air pollutants present in exhaust streams. Operating at temperatures ranging from 815°C (1,500 F) to 980°C (1,800 F), RTOs combine VOC-laden air with oxygen, breaking down the VOCs into three outputs: Carbon Dioxide (CO2­­), Water (H2O) and Heat.

The CMM Group manufactures RTOs ranging from 2,500 Square Cubic Feet Per Minute (SCFM) to over 100,000 SCFM, and customized to handle various exhaust streams.

How Does a Regenerative Thermal Oxidizer Work?

In operation, the process exhaust fumes are pushed or pulled into the Regenerative Thermal Oxidizer inlet manifold using a high-pressure supply fan. From here, the exhaust is directed to an energy recovery chamber, before being directed to a ceramic canister, where the pollutant laden air adsorbs heat.

After passing through the ceramic media, the pollutant-laden air heads to the combustion chamber, where it is held at the necessary temperature for destruction. After oxidation, the hot air is directed through a second energy recovery canister, in which the air is cooled and then routed to the exhaust manifold. Throughout the process, the airflow is switched so that one ceramic chamber heats the air and the other cools it.

Typical Regenerative Thermal Oxidizer Applications

As RTOs destroy VOCs and other pollutants at highly elevated temperatures, they are best suited for the following industries and applications:

While the chemical processing, coatings, and paint industries are unique and have unique needs, companies in these industries often find the RTO as the most effective option to control VOC emissions.

Chemical processing companies are among the most stringently regulated, requiring a 98% VOC destruction efficiency in order to remain compliant with national industry standards. An RTO is often the most effective solution for chemical processing, due to the 99%+ destruction efficiency, thermal efficiency, and ability to be customized.

The CMM Group is a proven leader in the manufacturing of RTOs for each of these industries, and has the results to back it up:

Another top industrial application for which RTOs are a good fit: Packaging and Printing. As companies in these industries need to reduce not only their VOC emissions, but minimize odor as well, RTOs are well suited and can be customized to handle the unique needs of printers and packaging manufacturers.
The CMM Group has built RTOs for many such organizations in these industries, reducing emissions generated during the printing process, including the following:

In Fiberglass-Reinforced Plastics (FRP) manufacturing, the manufacturing process generates a wide variety of VOCs including styrene and methyl methacrylate, and the RTO serves as an effective, efficient, and scalable option to destroy these pollutants.

How is a Regenerative Thermal Oxidizer Manufactured?

The manufacturing process of a regenerative thermal oxidizer begins with a discussion with The CMM Group team, who will take into consideration the production process, documenting the following:

  • Potential installation locations
  • Operation times (hours/day, days/week)
  • Number of emissions points to be controlled
  • Exhaust rate of each emissions point
  • Temperature of each emission point
  • Potential fuel sources

Regenerative Thermal Oxidizer Parts and Components

As an RTO is completely customized for your processes and exhaust streams, there are many different parts that go into the design and manufacture of the RTO:

  • Process Exhaust Inlet and Supply Fan
  • Heat Exchange/Ceramic Media
  • Combustion Components
  • Fuel Source/Burner
  • Outlet Valve
  • Airflow Switching Valves
  • Enclosure/External Shell
  • Programmable Logic Controllers/Technology
