Eminox provides aftertreatment systems and integration solutions that help to improve air quality by reducing harmful emissions from diesel engines. Our expertise includes technologies for the reduction of particulate matter (PM) hydrocarbons (HC) carbon monoxide (CO) oxides of nitrogen (NOx) and how to combine them to meet the emissions requirements of Stage and Tier legislation.

We can provide a complete system integration solution for your Stage IIIB aftertreatment system, including pipework and silencers, to meet the space envelope of your equipment. We can support engine manufacturers and equipment manufacturers in the design and manufacture of emissions systems and components required for Stage IIIA, Stage IIIB and Stage IV legislation in Europe and Tier 3, Tier 4i and Tier 4f legislation in the US.


We also design and manufacture retrofit emissions systems to meet local air quality requirements.
We are a proven supplier of exhaust systems, incorporating mufflers and or spark arrestors, for non road original equipment (OE) manufacturers, including Caterpillar; Terex-Demag and Liebherr. Our engineers design the complete exhaust system to meet manufacturer's and legislative requirements in configurations to suit a wide range of vehicles from cranes to articulated trucks, to quarrying vehicles and heavy duty excavators. The durable stainless steel construction makes them ideal for the demanding non road environment which can subject vehicles to continual physical stress. More information on delivering a complete project can be found in the Doosan Moxy case study.
Our packaging and integration expertise is supported by our proven experience of emissions technologies including:
We use a range of techniques as part of our system integration and component design process, allowing us to predict air flow, back pressure, acoustics and noise attenuation. Our practical injection and mixing technology experience is supported by CFD analysis.
Combined with our rapid prototyping and testing capabilities, we can deliver a complete project from concept to supply.
