Wärtsilä Oil Mist Separator for engine crankcase ventilation

The Wärtsilä Oil Mist Separator for engine crankcase ventilation removes more than 98 percent of the oil mist in the crankcase ventilation gas. The oil mist resembles smoke since the droplets are very small in size, between 0.1 and 2 μm, which is why it has previously been difficult to remove them effectively.

    Technical info
    The key component in the module is an electrically driven separator. The engine crankcase ventilation gas is fed to the separator where the oil particles are centrifuged and collected in a small container. The oil is then fed back via a drain pipe to the engine. A frequency converter boosts the speed of the electric motor to improve separation efficiency. The separator unit is regulated by a throttle valve on its inlet pipe to match the gas flow from the engine or engines.
    Benefits
    • Removes oil particles from the engine crankcase ventilation gas on diesel and gas engines
    • Safe and easy to install
    • Enables cruise and passenger vessels to avoid problems caused by oil mist
