Filtration system extends oil life

Home Engineering Motors Filtration system extends oil life

SKF’s oil filtration system, which removes nano-sized impurities, is now available in compact form, helping a wider range of users to reap the benefits of cleaner oil.
RecondOil Box is a smaller version of SKF’s industrial scale DST systems, which have previously been applied in large applications in metal working and quenching.

The smaller system is suitable for a broader range of industries and applications, to name a few: general manufacturing pulp and paper production; metal production; metal processing and energy production.

While conventional filters typically only remove particles in the micron range, the RecondOil Box features Double Separation Technology (DST), which can remove particles down to nano-size from an oil. It acts as a mechanical ‘kidney’ in a machine’s oil circulation system, where it regenerates the oil by progressively removing contaminants, and then returning the oil back into circulation. As the oil is in a closed loop, it’s kept at a highly clean state continuously.

By keeping the oil continuously clean, RecondOil Box can signifi-cantly extend oil change intervals.

“When DST-regeneration is combined with lubrication management and condition monitoring, oil can be circulated and re-used for much longer,” says Erik Råwall, Programme Manager at SKF. “Sometimes, it can be circulated indefinitely, allowing a circular use of oil.”

So, as well as reducing the cost of replacing oil, it can also deliver an environmental benefit. A lifecycle analysis performed by IVL Swedish Environmental Research Institute calculated the climate impact of a conventional oil cycle at 3,830 kg CO2 equivalent per m3 of oil – compared to 8.2 kg CO2-eq with RecondOil Box.

The nano-clean oil can also improve machine performance across a range of applications.
