Emmie 2

The Alfa Laval Emmie 2 is a mobile centrifugal separator that makes it easy to remove particles and water from industrial oils. The Emmie 2 helps to increase oil lifetime and reduce equipment wear. Its mobility and ease of connection make it ideal for several tanks and small installations.

Solid-liquid separation centrifuge

Easy, affordable, effective

  • Installed in a bypass flow so no machinery alterations required
  • Plug-and-play operation
  • Requires no supervision once started
  • Disc stack separator provides rapid, simultaneous and continuous three-phase separation of water and particles
The Alfa Laval Emmie 2 is a complete cleaning system including separator, feed pump and controls. It can be supplied with or without a heater. It extends oil lifetime, increases uptime and reduces equipment wear. It removes virtually all water and more than 99% of solid particles 2-5 µm in size (but no additives) from any service oil. Under normal operating conditions, payback time can be less than a year.

How it works

The Alfa Laval disc-stack centrifuge efficiently separates the solid and liquid phases from each other. Traditional settling tanks use gravity to separate phases. Due to the high rotational velocity, the Alfa Laval centrifuge separators speeds up separation by 5,000 times using centrifugal force instead of just gravity.


The force presses heavy particles outwards against the separator walls. The disc stack inside the separator bowl ensures lighter particles follow the heavier ones instead of the liquid, making separation more precise and efficient.
