C0 Oxidation Catalysts

Maxim Silencers CO Oxidation Catalysts oxidizes Carbon Monoxide (CO), Hydrocarbons (HCs), Volatile Organic Compounds (VOCs), and Hazardous Air Pollutants (HAPs) from lean burn internal combustion engines. The technique of maximizing surface exposure of the precious metals on the substrate results in a high activity catalyst that is both durable and efficient.

Maxim Silencers can provide standard catalysts; Available in round, rectangular, oblong and octagonal configuration. No engine is too big or too small. Let us design and build a catalyst for your IC engines and run with the confidence of guaranteed compliance. Replacement elements can be made to fit any existing housing in all shapes & sizes including brand name replacements. Maxim Silencer catalysts are proudly made in the USA.
