With many different suppliers and brands available on the market, it can be hard to choose the right supplier for your exhaust after treatment system. XEAMOS provides bespoke systems, which have been created in-house by our own experts. This makes that in our production process, we aren't dependent on other parties, but we are able to focus on your requirements entirely. Diesel particulate filters and noise reduction solutions combined with the latest technology create systems which will fit your specific situation. Up-to-date information about emission regulations is automatically taken into account when designing a solution so that we can provide you with an efficient and durable product.
The choice of sytems can seem overwhelming. To make a well-considered choice, there are a few specifications which can help to guide you in the right direction. Below are listed a few of these specifications which are crucial when considering buying a new system.
Spare part costs
All systems need maintenance. The costst of this will depend on the materials that are used and the frequency of replacement. XEAMOS designs systems with durable and cost-effective parts, ensuring that the maintenance costst will stay as low as possible.
Space is often limited in vessels or in industrial machines. This also has consequences for the used systems; smaller models generally are less efficient when it comes to the noise reduction as well as the needed maintenance. Furthermore, more compact engines also have a higher back pressure.
The load profile of the engine is another important variable. Not all filter systems are particularily suitable for a longer duration with lower engine loads.
Systems are built based on several parts. These parts are originally destined to be used in either mobile equipment machinery or industrial applications. The original destination of these parts is also decisive for the lifespan of the parts and the system as a whole. We design our systems so that the lifespan of the used parts equals the lifespan of the system.
When nitrogen(N2), which is always present in the air, is burnt or oxidized, the result is nitrogen oxides. At high temperatures, nitrogen reacts with oxygen (O2) which results in both nitrogen monoxide (NO) and nitrogen dioxide (NO2). The combination of these substances is called NOx. Together with other molecules such as hydrocarbons, oxygen and ozone, NO2 causes smog. Combined with water, this will lead to acid rain and when inhaled, human airways will suffer damage. Knowing that NOx forms in every combustion engine, it is no suprise that many national and international governmental bodies have developed strict regulations for the emission of NOx.
In the Netherlands for example, the legislation for NOx emissions is based on the recommendations of the World Health Organisation. Combined with regulations for other types of emission, these rules are bound to be tightened even more in the nearby future.
Soot, or particulates, is residue from carbon particles, ash and other wear particles from the engine. These particles are so small that they will access lungs when breathed in; even smaller particles can even enter our bloodstream. The smaller the particle is, the bigger the hazard is for our health.
These specific particles, which form a risk, are named PM10. The number in this name refers to the size of the partcile, which is 10 micrometres. In the nearby future, it is very likely that there will be set limits for the particle quantity of inland navigation engines exhausts.
Catalytic converters as well as diesel particulate filters already have a rather high noise reduction. This reduction mostly takes place in the upper frequency areas as a result of the design of the reactor housing. However, to also achieve noise reduction in the lower frequencies, it inevitably also means that there is more volume needed.
Smaller systems which have a lower noise reduction can therefore combined with, for example, a post silencer or a wet exhaust system. By cleverly combining sytems where noise reduction is also achieved you'll have a compact and efficient sytem which also reduces the noise up to 40dB(A).
