Situated after the charge air cooler, the water mist catcher (WMC) separates water droplets from the cooled air. The droplets naturally condense from humid hot air during the cooling process. It is advantageous to remove this moisture before it enters the engine.
For larger 2 stroke engines the water mist catcher is a separate unit placed in the cooler housing.
On 4 stroke engines some charge air coolers have an integrated water mist catcher.
Vestas produces WMC’s for new engines as an OEM product. The designs remain closely aligned with the standards demanded by MAN Diesel.
Although not often required to be replaced, Vestas also supplies replacement WMC from its aftermarket department
