Name	Photo	Description
Diesel Particulate Filters		Create a chemical reaction with exhaust gases as they pass over the catalyst material. This reaction reduces some of the particulate matter and converts a large portion of carbon monoxide, hydrocarbons and other emissions into carbon dioxide and water. (more)
Emission Applications		Whether it is electric power generation, truck or industrial engines, we will work with you to customize the right emissions control device to get your emissions issues taken care of professionally and promptly. (more)
Oxidation Catalysts		Through chemical reactions, Caterpillar Oxidation Catalysts will help lower engine emissions. (more)
Selective Catalytic Reduction		Effectively reduces emissions of nitrogen oxides (NOx). By injecting urea (a non-hazardous form of ammonia) into the hot exhuast stream, this process reduces most exhaust emissions to harmless nitrogen water vapor. (more)
