Where diesel retrofit creates operational value
We apply retrofit and emission-control solutions in sectors where diesel particulate, NOx exposure, ventilation limits, asset life and operational continuity all matter at the same time. That is especially true in underground mining, tunnels, rail maintenance operations and demanding heavy-equipment duty cycles.
Sector overview
Retrofit is most valuable where the machine still delivers operational value but must adapt to new environmental, occupational or procurement requirements.
Mining, tunnels, rail and heavy machinery share a common need: control diesel particulates and NOx without the cost, downtime and engineering burden of replacing the entire platform when that is not necessary.
Mining and tunnels
Aftertreatment systems for underground diesel equipment where occupational exposure, ventilation capacity and compliance obligations directly affect production and safety.
- Control of diesel particulates and NOx in confined spaces
- Retrofitting of existing mining and tunnel equipment
- Engineering response to air quality, safety and operation requirements
Rail
DOC, DPF and SCR integration on rail maintenance equipment to reduce emissions in tunnels, depots and high-demand operating environments.
- Dresinas, tampers and profiling machines
- Engineering driven by packaging, temperature and duty cycle
- Reliability-oriented integration approach
Heavy machinery
Retrofit of heavy equipment to reduce emissions and extend asset life without unnecessary redesign or fleet-wide replacement.
- Construction, civil works and industrial machinery
- Mining support equipment and specialised diesel platforms
- Project-by-project engineering approach
Stationary engines
Emission control design and aftertreatment integration for stationary engines and industrial power systems.
- Industrial installations and generator sets
- Application-based engineering design
- Maintenance and long-term system follow-up

Experience in critical applications
Filter Solutions sector content is based on practical integration work in industrial environments where compliance, diesel exposure and real operating constraints cannot be separated from engineering decisions.
