Six benefits of using nanolubricants

An extended lubricant lifespan

The process by which a protective layer forms between the lubricant and the friction surface, also results in a lower lubricant temperature. The layer furthermore reduces shear stress on the lubricant and limits contamination with wear particles.

The overall result is that our lubricants last up to 10 times longer than traditional products. For example, a customer who previously had to change oil every 250 working hours, found that after 1,900 hours our lubricant was still in excellent condition.

Higher fuel efficiency

The extra layer that forms between our lubricant and the surface considerably reduces friction. Less friction means a higher power output, which increases the engine’s fuel efficiency and helps lower CO2 emissions.

Test results show that our nanolubricants reduce zero load losses by more than 20%. In a real-life situation, reduced friction was found to reduce energy consumption by 28 kWh, representing annual cost savings of thousands of euros.

Lower oil temperature and thermal load

Less friction means lower peak temperatures. In our real-life test facilities, it was confirmed that our nanolubricants result in a considerably lower thermal load. When used in a reverse gear belonging to one of our customers, temperature reductions of 9 °C were confirmed.

When peak temperatures drop below the critical threshold for NOx, considerable reductions of emissions are possible. Using one of our nanolubricants in a 12-cilinder car engine, for example, resulted in an 80% drop in NOx emissions.

Lower maintenance cost

The highly elastic and robust protective layer formed by our nanolubricants enables both an extremely high load-carrying capacity and an extraordinarily low wear rate. For example, when tested for use in a wind turbine gearbox, one of our lubricants easily reached the highest load stage available (>14), while wear was extremely low.

Our nanolubricants can also be used to regenerate used sliding/friction contact areas, by removing residues and by forming a new wear protection layer.

Smooth and stable operation

The highly stable protective layer reduces the mixed friction ratio. This results in a significant reduction of noise and vibrations, and improves the smooth running of engines and other rotating equipment.

In the case of one gearbox, installed in a fishing vessel, replacing the existing lubricant with a Dex product was enough to make a persistent hammering sound disappear. The same effect can be achieved in a wide range of applications. For example, in order to minimise vibrations in delicate production processes.

Better cold-start performance

The friction-reducing effect of our nanolubricants considerably improves cold-start performance in very cold conditions. The lubricant can be pumped around much more easily, resulting in lower wear, higher efficiency and improved yield stress.

Tests show that at a temperature of -30 °C Dex lubricants perform much better than traditional products, and the difference will be even more marked for lower temperatures.
