RETOX Regenerative Thermal Oxidizer (RTO) System: Tower-Type

CECO Adwest has installed over 200 multi-tower regenerative thermal oxidation systems worldwide since 1997. We have provided tower RTO thermal oxidizer solutions with low cost and high benefit for ethanol, wood products, paint finishing, flavors & fragrances, food processing, building products, petrochemical and pharmaceutical applications. Our multi-tower technology can provide up to 99%+ emission reductions of volatile organic compounds (VOCs), acid and malodorous process streams.

Operating flow control of a tower-type RTO Thermal Oxidizer – Inlet/Outlet/Purge

The VOC laden air is directed by the flow control (poppet/butterfly) valve mechanism to flow through up to 9 beds into the combustion chamber where the VOCs are purified. These RTO ceramic media beds are designed to provide up to 97% primary heat recovery and produce very high rates of heat transfer. This results in the air being preheated very close to the required oxidation temperature (1500 to 1700 degrees/f) by the time it reaches the combustion chamber requiring minimal auxiliary fuel input to the RTO system.

The clean air then exits the combustion chamber through an outlet bed or beds that have been previously cooled. As the air passes through these beds it is cooled by the same heat transfer process. After passing through the outlet beds the air exits the RTO system at a temperature only slightly higher than the inlet temperature.

After several minutes the first set of inlet beds becomes depleted of heat while the second set of beds (outlet) becomes preheated with the heat liberated from the combustion process. At this point the flow of air through the beds is switched with the previous inlet beds acting as the outlet beds and the former outlet beds acting as the purge bed. The purged bed becomes the inlet bed. In this way each bed periodically extracts heat from the clean gas stream exiting the combustion chamber then releases this heat into the polluted gas entering the combustion chamber. A dedicated purge bed is utilized with tower RTOs to assure 100% capture of the VOCs and treatment on the inlet bed side. This method is thermal regeneration. The combination of thermal oxidation and regenerative heat recovery allows the RTO Thermal Oxidizer system to efficiently destroy VOC laden air with minimal operating costs.

Typical Thermal Oxidizer Applications:

  • Petrochemical and Refineries
  • Wood Processing & MDF/OSB Mills
  • Paint Spraying and Finishing
  • Rubber Processing
  • Packaging/Printing
  • Food Processing/Flavor & Fragrances
  • Pharmaceutical
  • Biodiesel/Ethanol Processing
  • Semiconductor
  • Wastewater/Municipal Odor Control
  • Coal Bed Methane VAM Abatement

Wound Polypropylene Depth Filter Cartridges – Sethco


Wound Polypropylene Depth Filter Cartridges

Our CECO Sethco filter tubes are fabricated of natural or synthetic fiber wound over a perforated plastic or metal core. The precision winding pattern covers the entire depth of the filter tube with hundreds of funnel shaped tunnels which become gradually finer from the outer surface to the center of the tube and trap progressively finer particles as the fluid travels to the center. This allows much greater solids retention capacity than is associated with surface filter media of the same dimensions.


CECO Sethco is a leading manufacturer of premier pumps and filters for use in a variety of industries. Industry professionals know that Sethco products are dependable, safe, and efficient from day one when dealing with the corrosive and hazardous chemicals found in the electronics and metal finishing processes. When it comes to dependability, Sethco sets the standard for the industry. 

Sethco is global leader in providing products with an exceptional reputation. Our Wound Polypropylene Depth Filter Cartridges deliver superior filtration for trapping and retaining particulate contaminants. That is why petrochemical, metal finishing, wastewater treatment, desalination, and aquarium businesses all over the world trust Sethco filter cartridges.
