SKF RecondOil Box – Sustainable Oil Regeneration System for Industrial Applications
Don’t change oil. Change to circular use of oil.
The SKF RecondOil Box transforms how industrial plants manage lubrication oil. Instead of regularly changing and disposing of contaminated oil, this system regenerates oil in-line, keeping it cleaner than new—and usable indefinitely.
With patented Double Separation Technology (DST), the RecondOil Box removes contaminants down to nano-size particles, including varnish, water, and oxidation by-products, which conventional filters can’t touch. The result is ultra-clean oil that delivers longer machine life, reduced downtime, and significant cost savings—all while cutting up to 99% of CO₂ emissions compared to traditional oil replacement cycles.
Whether you’re in mining, pulp & paper, cement, steel, marine, energy or automotive manufacturing, the RecondOil Box offers a sustainable, performance-enhancing solution that pays for itself.

How It Works
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 systems. 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

RecondOil Box Overview
FAQs
Do I still need to change the oil periodically?
No. With the RecondOil Box, oil is continuously regenerated. In many applications, oil life becomes indefinite.
What types of contaminants does it remove?
Nanoparticles, varnish (soluble and insoluble), water (dissolved, emulsified and free), and oxidation by-products.
What is DST (Double Separation Technology)?
DST is a patented chemical/mechanical separation process that removes particles far smaller than conventional filters can capture.
How long is the payback period?
Many customers experience a payback in less than a year through reduced oil purchases, maintenance, and downtime.
