SSI's latest series of centrifugal oil separators represent the next generation in commercial separation technology.

SSI separators clean oil using centrifugal force 2000 times greater than gravity. They remove contaminants that cause damage to engines and also greatly extend the life of lubricating oil in both engines and gearboxes.

This new product is not only suitable for the marine and offshore industry but also for applications within the power generation, industrial manufacturing, mining and automotive sectors.

  • Why is a Centrifugal Oil Separator so important in
    today’s modern high performance diesel engines?

    The problem

    Nearly all full-flow oil filters are designed to clean the lubricating oil which lubricates the moving parts of engines. They are designed for a certain flow rate and pressure drop.

    However, to get the necessary flow rates and pressure drops required there is a trade-off in performance. Smaller submicron particles pass through the filter media continually.

    These particles build up in the lubricating oil, causing unnecessary wear and damage to the engine, which in turn leads to lower engine performance and increased engine emissions. They also shorten the life of the lubricating oil as the level of contaminants increases.

    With today’s emission controls getting tighter and tighter, it is increasingly important to remove these contaminants before they cause any damage to both the engine and the lubricating oil.


    The solution

    By adding an MP Centrifugal Oil Separator the amount of particles in the lubricant is significantly reduced.

    The centrifuge bypasses only 10% of the dirty oil but by doing so it significantly improves the quality of the lubricant  increasing the life and efficiency of the full flow filter.

    With fewer particles moving around the engine, wear and tear of components is greatly reduced and has the added bonus of reducing man hours due to unnecessary servicing.

    Environmentally, fewer contaminates in the oil also mean lower emissions - a must in today's environmentally sensitive times.

    Only 10% of dirty oil is fed through the MP Centrifugal Oil Separator, however, this provides significant improvements to running times between services and lubricant longevity. It also reduces man hours by eliminating unnecessary servicing.

  • The SSI Centrifugal Oil Separator is impressively effective

    In a standard system with only the full-flow filter, total insolubles (% mass) rise to 3% within 200 hours. After 700 hours with an SSI centrifuge added to the system, the mass insolubles remain below 1.5%.

  • How it works

    The highest performing and only self-monitoring bypass oil filtration spinner-type separators in the world.

    Unique solution

    Oil is introduced into the separator bowl at engine oil pressure through holes drilled in the vertical spindle and via the accelerator channels in the bearing distributor.

    The bowl then fills up and oil overflows into the top turbine where it exits the bowl via the four speed turbine channels and then out via the nozzles. This in turn rotates the bowl, generating the centrifugal force required to remove the contaminants from the oil.

    The contaminants migrate towards the outside of the bowl where they are deposited on a removable oil resistant insert. The cleaned oil migrates towards the centre of the bowl, where it is expelled by the nozzles in the top turbine, thus perpetuating the cycle.

    Increased efficiency

    Unlike conventional centrifugal spinners/separators, SSI separators use bowl discs to increase the efficiency of separation, dramatically reducing the time that contaminants can stay in the oil.

    We have also improved the sealing between the dirty oil inlet and the cleaned oil outlet.  This ensures that there is minimal cross-contamination between the two.

    Save valuable man hours

    SSI Centrifugal Oil Separators also have dirt/sludge monitoring technology, which informs the operator when the separator needs cleaning, saving valuable personnel time on otherwise unnecessary cleaning.

    The system is both MODBUS and CANBUS compatible and can be easily connected to your existing alarm systems.
