Versatility and simplicity

We know that choosing the right type of scrubber for your operations is important. That’s why Wärtsilä has developed three kinds of standard scrubber designs to better meet the demands of our customers.

Wärtsilä can offer the conventional venturi scrubber design, as well as the more compact inline scrubber system. Both scrubber designs have benefits and drawbacks dependent on vessel type and layout, which is why our experts work closely with you to recommend what makes sense at a vessel and fleet level.  

Wärtsilä’s exhaust gas treatment systems have superior uptime and some of the best quality of engineering in the market across the globe. Our scrubbers are highly dependable, reliable and safe, providing owners and operators with a high amount of assurance when using these solutions in-operation.

Our exhaust gas treatment systems have been tested and certified according to IMO guidelines, thus ensuring safe operation and compliance.

Most importantly, our systems are simple, and we work with your maintenance and operations teams to ensure that there is minimal impact to their workload.

There is a lot more to exhaust gas technology than Sulphur

Exhaust treatment

The IMO 2020 low Sulphur fuel oil transition has proven that the shipping industry can successfully manage huge changes. The next stage is to tackle the other harmful elements in exhaust gasses.

There is every likelihood that more stringent rules that further limit SOx, nitrogen oxides (NOx), particulate matter (PM) and black carbon will come into force. Wärtsilä has therefore adopted a new way of thinking about scrubbers beyond SOx to solve these future challenges.

By adopting a modular approach, continuous research and development, and prioritizing innovation, we will continue to supply the industry with assured lifecycle solutions that will safeguard assets into the future and generate real progress on sustainability targets.


Wärtsilä Exhaust treatment solutions


Open loop, closed loop, or hybrid

Once the right design has been chosen, we can adapt our scrubbers to serve open loop, closed loop or hybrid applications. We do this by working with our customers to understand their requirements, operating patterns and routes.

 No matter the design or operating mode, our exhaust gas treatment systems can go beyond compliance.

Additionally, we are currently the only scrubber manufacturer that offers these systems to the market with water treatment capabilities, in order to ensure the safest possible discharge back to seawater.
