CECO Thermal Abatement Solutions, comprised of Adwest and EIS, is a global leader in thermal and catalytic oxidizer design, manufacturing and installation to reduce volatile organic compounds (VOCs), with over 2400 Regenerative Thermal Oxidizers (RTOs) and VOC abatement systems installed across the globe over three decades.


Regenerative Thermal Oxidizers (RTOs) abate Volatile Organic Compounds (VOCs), CO, odor and hazardous air pollutants (HAP) that are created through chemical processes, and industrial exhaust streams by combusting or oxidizing them into carbon dioxide (CO2) and water (H2O) using extremely high temperatures. 

This type of oxidizer uses extremely high heat, about 1500°F, to clean the exhaust of dangerous pollutants and compounds. Developed for emissions with large volumes, and low VOC concentration applications, RTO technology uses ceramic media as heat exchangers, and switching values. In this configuration, among other distinctions, the outgoing clean process stream of the secondary heat exchanger process is routed to another part of the plant for its use or back to the process itself.

TRUSTED Technology

Not all air abatement products are created equal. Our Regenerative Thermal Oxidizers (RTOs) have been developed to minimize the environmental impact of emission remediation by providing high destruction rate efficiency (DRE), solvent and heat recovery. 

RTOs are a safe and effective method of abatement with the following key attributes:

High DRE rates in large volume streams

Reduce fossil
fuel usage with heat recovery

Multi-canister designs available to treat all size applications

Long and reliable life-span of eqiupment with regular maintenance

The 3 T’s of Fume Incineration & Thermal Oxidation Design Success




Adwest RTO
>1500 F is recommended for thermal oxidation reaction without auxiliary VOC catalyst (catalysts typically light off many VOCs at 550- 800 F )—temp provided by burner (nat gas, propane, oil fired) or electric heat elements.
Adwest RTO
VOCs spend >0.5 s to up to 2.0 s RT at high-temperature retention time (RT) to ensure complete oxidation of longer chain hydrocarbons, ketones and aldehyde compounds. 
Adequate mixing of O2 with VOCs is required inside the oxidizer; each VOC molecule needs an equal proportion of O2, otherwise, no reaction (typically requires 16 mole % O2 in process for proper combustion). 







Founded in 1988, Adwest began providing compact, skid-mounted and cost-effective VOC air abatement solutions to a wide range of industries. A leader in thermal and catalytic VOC abatement solutions, Adwest custom designs and manufactures highly efficient thermal abatement solutions. We were a pioneer in compact electric RTOs with flameless NGI operation, which provided NOx-free operation – an industry first.

EIS provides cost-effective solutions for industrial customers faced with air pollution control issues. Our approach includes tailored design and technology packages and a “whole of life” analysis, part of the unique qualities that our customers have come to expect. We manufacture systems that target reducing odor, abating VOCs, and recovering solvent or removing acid gas.
