Catalytic oxidizers are devices used to reduce harmful emissions from industrial processes. They work by promoting a chemical reaction that converts volatile organic compounds (VOCs) and other pollutants into less harmful substances, primarily carbon dioxide and water. This process occurs at lower temperatures compared to traditional thermal oxidizers, making it more energy-efficient. These systems utilize a catalyst, often made from materials like platinum or palladium, to accelerate the oxidation reaction. Catalytic oxidizers are commonly used in industries such as automotive, chemical manufacturing, and printing, helping to meet environmental regulations and improve air quality.
