Catalytic Thermal Oxidizer CATOX


Catalytic oxidation of VOCs at a lower temperature, with fewer emissions and lower energy consumption.

These installations are used to reduce industrial gas flows that are contaminated with volatile organic compounds (VOCs). Also known as CO, CATOX, CTO, RCO or CRO, a catalytic oxidizer works by increasing the temperature of the exhaust stream to the point where the chemical bonds that hold the VOC molecules together are broken (oxidized). The VOCs from the process exhaust stream are converted into carbon dioxide (CO2), water (H2O) and thermal energy. In a catalytic oxidizer, the operating temperature is significantly lower than with direct thermal oxidation, and the system is often virtually self-sufficient, requiring minimal auxiliary fuel to support the process.

If you are looking for this system, Electron will of course help you with information and advice and we will look at which application best suits your specifications.


Due to the lower operating temperatures, a Catalytic Oxidizer generally consumes less energy

Lower operating temperature results in less NOx

Requires less space than other installations

Lower amount of emissions

Yield up to 99.99%

Best commissioning times in the industry

Eliminates as much or more than 99% of hazardous gases, meeting all EPA requirements for MACT, RACT, BACT and LAER

A catalyst is a substance that speeds up the rate of a chemical reaction without being consumed in the process. The process of catalytic oxidation not only consumes less fuel, but also operates at a lower temperature, minimizing the formation of NOx. The reduction of CO and minimization of NOx formation are very important, as both compounds are regulated as strictly as VOCs by the Environmental Protection Agency (EPA).

A catalytic oxidizer has a relatively short warm-up time and can operate in shorter periods (non-24-hour continuous cycles) without adversely affecting the overall life of the equipment and associated components. In addition, the use of catalytic systems, with a relatively low VOC load, can reduce the total annual operating costs compared to direct fired thermal oxidation, regenerative thermal oxidation, or thermally recuperative oxidation.
