How it works

Emmie consists of a stainless-steel trolley and a centrifugal separator with two bowl sets – one for purification and one for clarification. All elements are built on the unit so it's easy to move from tank to tank.

The purifier mode is ideal for applications where oil is heavily contaminated with water because it removes water continuously.

Centrifugal force separates solids from the oil and feeds them outwards for easy removal. Water continuously discharges from the bottom of the bowl. If oil only has traces of water, clarifier mode blocks the water outlet. You can switch between modes in minutes.
