SKF RecondOil Box
The SKF RecondOil Box is a high-performance oil treatment system designed in a compact and robust package. It continuously removes nanoparticles, varnish, and moisture from the oil, significantly extending its service life and reducing or even eliminating the need for oil changes. In many cases, the regenerated oil is cleaner than new—resulting in improved machine performance and transforming oil from a consumable into a sustainable, reusable asset.
The Lifetime of Oil is Influenced by Contamination
Nanoparticles
Microparticles that most often can be removed from oils with conventional filters make up for about just 20% of the total surface area of all particles in an oil. At the same time, nano particles that normally slip through conventional filters constitute the remaining 80%of the surface area. The nanoparticles cause severe harm – and they are a catalyst for oxidation in the oil. Oxidation accelerates the oil’s aging process.
Varnish
The growing popularity of the highly-refined Group II and Group III base oil composition has played a role in the increasing prevalence of varnish-related issues in oil – these base stock oils have lower solubility for varnish-forming materials.
And while there are several causes for varnish formation in an oil, oxidation by-products are seen as the primary source.
Varnish causes machine wear and thermal stress as well as accelerates the oil’s degradation process.
Water
For most oils, water ingression can compromise nearly every beneficial property. The presence of water in a system can cause corrosion and reduce component life. Water also affects the oil’s viscosity and deteriorates its lubricating properties.
One System – Three Functions

We can get rid of the nanoparticles – and all other particles as well, for that matter. This means we can stop the oxidation process from even beginning and create a potentially endless oil life

With its DST filter, the RecondOil Box also removes both soluble and insoluble varnish, thereby avoiding clogged sys tems. Varnish removal also offers cooler operational temperature and longer component and oil life

In addition, the RecondOil Box is also efficient at water removal, and can remove dissolved, emulsified and free water out of an oil
