Exhaust aftertreatment and noise control
SCR, DPF, DOC and acoustic enclosures for gas and diesel generator sets, from sizing to commissioning and after-sales.
Figures from Treeing project records.
To be verified before launchEach system is sized to the engine model, exhaust flow and site conditions. Combine them when a project needs both emission and noise control.
Urea-based selective catalytic reduction for gas and diesel gensets, with closed-loop dosing control.
Custom enclosure that combines sound insulation, sound absorption, intake and exhaust attenuation, and cooling.
Wall-flow filter that captures soot from diesel exhaust and is cleaned by regeneration.
Precious-metal oxidation catalyst that converts CO and HC, and supports DPF regeneration.
Performance values depend on engine, fuel and site, and are confirmed for each project in the quotation.
A typical exhaust line on a diesel genset. We size each stage from the engine data sheet and the site emission limit. On gas gensets the line is often SCR only.
Engine data sheet and fuel
CO and HC, supports DPF regeneration
Soot and black smoke
Urea dosing and NOx control
Monitoring port and sampling
| Fuel | Main concern | What we ask for |
|---|---|---|
| Natural gas | Few contaminants. Design is driven by the NOx limit and exhaust temperature. | Engine data sheet, NOx limit and reference O₂ |
| Biogas and landfill gas | H₂S and siloxanes can poison the catalyst without gas pre-treatment. | Gas analysis and pre-treatment details |
| Diesel | Soot in the exhaust. DOC and DPF usually come before the SCR. | Engine data sheet, fuel sulfur content, duty cycle |

14 Jenbacher J320 gensets, 14,000 kW in total
85% NOx reduction
4 Cummins C1540 N5CC gas engines, 6,000 kW in total
92-93% NOx reduction in operation
We size each system from the engine model, exhaust flow, fuel and emission target.
Complete systems, or single units integrated with your existing equipment.
Installation supervision and on-site commissioning until the targets are met.
Long-term after-sales support once the system is in operation.
Our next-generation SCR controller is designed to install without field wiring and to be commissioned remotely, which cuts time on site. It is in field validation now. Our proven SCR systems remain the standard offer.
Send the engine model, fuel and the emission limit for your site. An engineer replies with a first assessment.
