Retrofit Solutions

Retrofit is a practical and cost effective solution, upgrading older diesel vehicles to the latest emissions standards at a fraction of the cost of new vehicles.

SCRT System

15 buses can be upgraded for the cost of 1 new bus
Particulate Matter   Particulate Number   Nitrogen Oxides   Nitrogen Dioxide
The Eminox SCRT® System can upgrade vehicles to emissions levels equivalent to Euro VI as well as reducing nitrogen dioxide (NO2). Emissions of nitrogen oxides (NOx), particulate matter (PM), hydrocarbons (HC) and carbon monoxide (CO) can be reduced by more than 95% [Details]

Standalone Selective Catalytic Reduction (SCR) Systems are also available [Details]

Eminox CRT® System - Continuously Regenerating Trap

Particulate Matter   Particulate Number
The Eminox Continuously Regenerating Trap (CRT®) is a market leading diesel particulate filter, it reduces particulate matter by mass and number as well as hydrocarbons and carbon monoxide. The passive regeneration capability makes this a simple and effective way to reduce emissions without additives. [Details]


Our retrofit systems are specifically designed to work in challenging urban environments, where pollution and population exposure is highest. Emission reductions are verified by independent testing and backed by real world in use data.
Our extensive applications engineering expertise enables us to design our systems to meet specific vehicles requirements, including challenging space constraints.
Our systems are approved for Low Emission Zones and E-Zones throughout Europe and have been used extensively in programmes to improve air quality. We meet the most challenging standards, such as the new London Ultra Low Emission Zone standard and Clean Air Zone requirements
