Fuel Filtration

Benefits

• Maximum wear resistance: Our high-end media achieve efficiencies of 99.99 % (Beta 10,000) to protect state-of-the-art common rail systems from even the smallest abrasive particles from 4 µm.
• Optimum service life: Thanks to innovative filter media, we offer up to three times the dust holding capacity (approx. 180 g/dm³) of the competition, enabling identical or longer service intervals despite critical fuel qualities.
• Long-term operational reliability: Highly efficient Water separator over the entire service life prevents corrosion and the formation of diesel pest.
• Sustainability and waste reduction: With the Blue.on [Link https://www.hengst.com/de/produkte/produktgruppen/43-kraftstofffiltration/1383-nachhaltiges-filtrationskonzept-blueon] concept, you reduce the amount of waste generated during maintenance by 90 % and the component weight by 25 %.

Challenge: Alternative fuels and material integrity

The use of biofuels (such as FAME or HVO), synthetic e-fuels and hydrogen is the key to reducing emissions, but presents filtration technology with completely new physical and chemical hurdles. Biofuels (biodiesel) in particular have a high ageing potential:

• Acid formation: Aging produces aggressive acids that can attack conventional filter media, housing and gaskets.
• Water absorption & diesel pest: A higher water absorption capacity favors microbial growth (fungi and bacteria) and leads to corrosion in the injection system.
• Particle ingress & flocculation: Paraffinic fuels such as HVO can flocculate at low temperatures, while contaminants from the global logistics chain (refineries, pipelines) endanger highly sensitive common rail systems.

Our answer: Technological safety through expertise At Hengst, we no longer just develop filtration solutions for standardized diesel, but for the global drive mix of the future. Using state-of-the-art testing methods in our Tech Center Filtration, we simulate artificial fuel aging far beyond industry standards to ensure the durability of our materials worldwide.

Tailor-made robustness for every challenge

Hengst Filtration not only offers standard products, but solutions that are precisely tailored to the extreme requirements of each industry. We understand that failure during harvest time or on the high seas is not an option.

On-highway: efficiency on the long haul

Off-highway: use under extreme conditions

Navy: Reliability on the high seas

Power Generation: Constant power for stationary systems

New Mobility: Filtration for hydrogen drives

On-highway: efficiency on the long haul

In long-distance transport, maximum mileage and minimum total cost of ownership (TCO) count. Modern common-rail systems in heavy trucks are optimized to the technical load limits and are highly sensitive to particles.

Our filters guarantee a first-class filtration effect over extremely long replacement intervals. This protects the injection system from wear, maintains the high engine efficiency and ensures the constant availability of your fleet.

Off-highway: use under extreme conditions

This is where highly sensitive motors encounter the harshest environmental conditions such as massive dust loads and extreme vibrations. Laboratory values often lose their validity in the field. Vibrations and pulsations in real operation can lead to particles that were safely filtrated in the laboratory suddenly reaching the clean side after all.

We test beyond industry standards on special vibration test benches and in real fleets. A Hengst filter that achieves a beta value of 1000 at 4µm in the laboratory maintains this performance even under massive mechanical stress in the field. This guarantees operational reliability even during the critical harvesting season or in tough construction site use.

Navy: Reliability on the high seas

In maritime applications, the focus is on ensuring operational safety in the face of highly fluctuating fuel qualities worldwide and efficient waste management. As ships bunker in different regions of the world, our systems prevent corrosion and diesel pest in the tank through highly efficient Water separator. Sustainable concepts also reduce logistics on board: a massive reduction in maintenance waste simplifies the disposal of hazardous waste, while a reduction in weight increases system efficiency

Power Generation: Constant power for stationary systems

Stationary engines and microturbines often have to start immediately and reliably after long downtimes. During long downtimes, biofuels (FAME) age particularly quickly and form aggressive acids that attack gaskets and media.

Thanks to our expertise in material integrity, we use materials that are proven to be resistant to these acids. Our modular systems (e.g. Blue.maxx) can also be equipped with integrated heaters to reliably prevent the fuel from flocculating in cold conditions.

New Mobility: Filtration for hydrogen drives

We offer a holistic protection concept for decarbonization.

• Fuel cell: Multi-stage cathode intake air filters (Blue.netic) protect the membrane from harmful gases in the ppb range through adsorption, while ion exchangers (Blue.iox) prevent impermissible conductivity in the Coolant.
• H2 combustion engine: An innovative active ventilation system minimizes the hydrogen concentration in the crankcase and thus effectively prevents the formation of explosive mixtures
