Alfa Laval’s PureSOx removes sulphur oxides from the ship’s exhaust gas by scrubbing it with sea water or fresh water.

The unique hybrid design of Alfa Laval’s PureSOx gives both environmental and economical advantages.

By using PureSOx, shipowners are enabled to continue operating on heavy fuel oil instead of more expensive marine gas oil while still meeting the strict IMO regulations regarding sulphur oxide emissions.
