EMMIE 2

Separator system for cost-effective cleaning of oil

Using high-speed centrifugal separation makes it possible to increase the reliability of the oil system and extend the service life of your oil. Alfa Laval’s disc-stack separators provide fast, efficient, simultaneous three-phase separation of water and particles.

Emmie.2 removes more than 99 percent of all solid particles between 2 and 5 μm from the oil, and virtually all of the water but none of the additives. It effectively separates airborne dust and undesirable particles from wear on paint, metal, plastic or rubber components from the oil. It also
removes water that causes additives to oxidise and decompose, too.

Emmie.2 removes contaminations from many different types of oils whether hydraulic or lubricating oil, compressor or gear oil, cutting or diesel oil. The result is lower costs due to prolonged service life of the oil and less disposal of filters and oil.

Emmie.2 is a complete compact system, including separator, feed pump and control system. The control panel makes it easy to operate. The unit is installed in a bypass system and operates continuously.

How it works

In a centrifugal separator, the gravity that causes separation in traditional settling tanks is replaced with a centrifugal force that can be more than 5,000 times stronger. Naturally, this makes separation significantly faster and more efficient.

If buffer plates are added to a settling tank, the sinking of any particles stops sooner, and there is a greater surface area onto which they will fall, helping speed up the separation process. In a centrifugal separator, the same basic principle can be applied, and a corresponding increase in effectiveness achieved, by a stack of special discs.

The centrifugal force presses any heavy particles present in the oil outwards against the walls of the separator, whereas any lighter particles tend to follow the liquid phase towards the centre. The disc stack prevents them from doing so, however, making the lighter particles change direction and end up with the heavy particles close to the outer wall.

This makes centrifugal separators an extremely effective way to remove solid particles many different types of service oil, as well as separating out different liquid components.
