Alfa Laval PureNOx has long been the choice for water treatment in Exhaust Gas Recirculation (EGR), a leading technology for Tier III NOx compliance. Today it’s available in an even more streamlined solution – PureNOx LS (Low Sulphur) – that supports both Tier III NOx compliance and Tier II fuel savings. PureNOx LS is optimized for EGR engines that operate on low-sulphur fuel. Upon request, solutions for use with high-sulphur fuel can also be tailored using PureNOx technology.
Optimization makes the difference
Developed in close cooperation with MAN Energy Solutions
Technology proven in thousands of hours of PureNOx operation
Streamlined design, optimized for EGR engines using low-sulphur fuel
50% smaller centrifugal separator module
More cost-efficient EGR
PureNOx LS reflects the global sulphur cap, which will lead to far more vessels sailing with low-sulphur fuel. Based on the latest engine maker guidelines, the system is optimized specifically to clean EGR bleed-off water in a setup similar to that of a bilge water system. The result is a smaller EGR water treatment system than ever before, but with the same reliable PureNOx technology. In turn, that means a more cost-efficient EGR solution. In addition, PureNOx LS has a unique strength compared to other systems on the market. It supports Tier II fuel savings with Eco EGR – and is the only water treatment solution that can.
How it works
PureNOx LS is designed for use with EGR engines that operate on low-sulphur fuel. In the EGR process, water is used to remove soot particles from the exhaust gas that is recirculated into the engine. This creates a certain amount of condensate
