Filtration technology
Our diesel cleaning machines are unique.
At Fuel-service AS, we are developers of diesel cleaning machines. We are currently at the forefront of diesel purification technology worldwide and are supported by the Research Council. To date, no one is more advanced than us. We have the knowledge, we have the technology, we have the experience.
Water affects the performance of diesel, leading to increased degradation and microbial contamination. The introduction of biodiesel has exacerbated this issue, but traditional EN590 diesel has not been spared; in fact, it has become more environmentally friendly, which in turn has made it more hygroscopic, similar to biodiesel. Traditional coalescing filters have therefore become much less effective. Based on these challenges, we offer filters that can absorb water to a far greater extent—300% better than other filter types available today. In addition to this immense water absorption capacity, our filters are designed for high flow rates. They can reduce water content from several thousand ppm to well below 50 ppm. This has been demonstrated and verified by Equinor with assistance on one of their platforms before startup. There is currently no other product that can match this performance for both fossil and bio-based diesel types; we are world leaders in this field. It is no coincidence that the largest data centers in Scandinavia exclusively use our filters, as well as installations in emergency services and restricted access areas.

Unbeatable super features of our filters:
- In 30 minutes, our filter cleaned 700 liters of diesel from 835 ppm to below 80 ppm.
- Our filters deliver unbeatable results, guaranteeing 100% water-free diesel and 99.9% removal of emulsified water.
- All tests were conducted with a Size 2 filter.
- Up to 3 times more water absorption than the nearest competitor.
- Impressive flow rate, up to 1000 liters per minute, with a mesh density of under 1 micron.
- Most circular economy-friendly solution – no landfill.
- Designed for both biodiesel and fossil diesel.
- Thoroughly tested by external laboratories.
