Caterpillar - Diesel Oxidation Catalyst / (Gas) Oxidation Catalyst

A flow through substrate coated with a high performance catalyst and housed within a stainless steel canister. Optional silencing available. Applicable to diesel engines and gas engines. Designed to selectively reduce NOx but can be combined with DOC or DPF technology to reduce multiple pollutants in a single package. System consists of SCR catalyst, static mixer, reactor housing, and dosing control system. Applicable to natural gas or diesel engines. Dosing control system injects Diesel Exhaust Fluid (DEF) into the exhaust upstream of the SCR catalyst. The DEF decomposes to ammonia (NH3), then passes through a static mixer and enters the SCR catalyst where NOx are reduced to nitrogen (N2).
