FAQ`s
How Does it Work
The exilator system is a combination of 3 technologies:
1. A silencer.
2. ExiBlock™, with licensed coating developed by NASA.
3. A special NOx catalyst.
In operation the exilator ignites and burns black soot (regeneration), when the exhaust gas temperature is above 325°C. The relative low soot ignition temperature is caused by the special coated ceramics.
The method is described as a "Passive Filtration System" and is less complicated than diesel pre-burners in terms of installation, operation and servicing.
The Exilator system combines a number of patented technologies:
Exiblock ™ coated ceramic internal honeycomb.
Servicing & Lifespan
Yearly servicing is recommended. During operation it is good working practice to periodically monitor back pressure, to ensure good working performance. Installation includes pressure gauges to easily monitor the condition of the filter(s).
- Maintenance/Cleaning can be carried out on board or in cooperation with Exilator’s local Partners.
- The maintenance/Cleaning intervals depend strongly on fuel type, age of engine, brand and use of additives.
- When running without fuel additives and fuel type with max 0.01% Sulphur (100 ppm, low sulphur diesel) the system can be expected to have long cleaning intervals and very long lifetime:
1. The normal service intervals are based on annual visit.
2. The expected cleaning interval is betwen 2.0000 and 5.000 running hours – but it is recommended to do annual cleaning irrespective of running hours.
3. The Round Filter Section and ExiBlockTM’s of the system are expected to withstand up to 10 times cleaning before the Filters/Filter Section must be replaced.
4. Cleaning and lifetime will be reduced significantly, when using fuel with higher sulphur content, using fuel - If using additives or “dirty fuel” the consequences can be:
1. Cleaning interval can be reduced by a factor 10-20%
2. The expected lifetime can be reduced by a factor 10 and the consequence can be that the filterblock(s) must be replaced.
3. For engines, with more than 2,500 running hours per year, the service visit should be carried out in connection with cleaning.
