Protect your yacht with Micfil ultra fine filters to clean oil and diesel from water, bacteria and particles
On modern superyachts, reliability efficiency and absolute operational security are essential. Main engines, generators and sensitive fuel injection systems operate under extreme demands and require fuel and lubricating oil of the highest purity. Even the smallest contaminants – water, bacteria, sludge, or microscopic particles – can lead to performance loss, increased engine wear, or in the worst case, complete engine failure.
In global yachting operations, where fuel is bunkered from different ports and suppliers around the world, consistent fuel quality cannot always be guaranteed. Micfil provides a reliable and long-term solution to this challenge.
Micfil designs and manufactures high-precision filtration systems for diesel, biodiesel and engine oil, specifically developed for demanding applications such as superyachts. With ultra-fine filtration down to 0.5 microns, Micfil technology removes even the smallest particles from the fuel while simultaneously separating water and microorganisms.
One of the most common problems in yacht fuel tanks is microbial contamination, often referred to as diesel bug. Condensation inside the tanks creates the perfect environment for bacteria and microorganisms to grow, forming sludge and deposits that clog filters, damage injection systems and threaten the reliable operation of engines and generators.
Micfil filtration systems eliminate up to 98% of bacteria in a single pass, while also removing water and ultra-fine particles. The result is consistently clean and stable fuel that protects the sensitive components of modern high-performance engines.
In addition to fuel filtration, engine oil purification plays a crucial role in maintaining the reliability and longevity of yacht propulsion systems and onboard generators. Micfil systems continuously clean the lubricating oil, removing soot, metal wear particles and oxidation residues. This keeps the oil significantly cleaner and preserves its lubricating properties for a much longer time.
In many applications, this technology allows operation without regular oil changes. Instead, the condition of the engine oil is monitored through regular oil analysis. As long as the analysis results remain within acceptable limits, the oil can remain in service because it is continuously purified by the Micfil system. For superyachts, this means reduced maintenance, lower operating costs and significantly less environmental impact.
Micfil’s fuel filtration technology can also significantly reduce harmful engine emissions. Measurements indicate that carbon monoxide (CO) emissions dropped by up to 75%, depending on engine speed and load conditions. Total particulate matter (TPM) – a key factor in air pollution – was reduced by up to 70%, while hydrocarbon (HC) emissions were also lowered in most operating modes.
Manufactured from high-grade stainless steel (V4A / 316) or aluminium (seawater proof) and designed for long-term use in harsh marine environments, Micfil filtration systems meet the highest standards of quality and durability. All filters are certified by international classification societies such as RINA and Bureau Veritas and are used worldwide on superyachts, commercial vessels and offshore installations.
Micfil provides clear advantages:
- Operational reliability of the yacht
- Optimal protection for engines and injection systems
- Clean fuel free from water, particles and bacteria
- Extended engine oil lifetime through continuous purification
- Reduced maintenance costs and lower oil consumption
With Micfil, superyachts benefit from cleaner fuel, clean engine oil and reliable engine performance anywhere in the world.
