At Hengst, development does not end in the laboratory. To ensure the maximum reliability of our filtration solutions, we have established a process that goes far beyond industry standards. We accompany every product from the first digital sketch to the final application in the vehicle under real operating conditions.
Phase 1: Simulation and design: We use state-of-the-art simulation tools right from the design stage to digitally optimize the flow behaviour and filtration efficiency.
Phase 2: Laboratory benchmarks according to ISO standards: We test efficiency and dust holding capacity according to ISO 19438 and Water separator according to ISO 16332. These laboratory tests form the basis, but often do not adequately cover fluctuating fuel qualities in the field.
Phase 3: The Hengst "Real Life" test:
- Vibration and pulsation resistance: in the real world, mechanical loads act on the filter. While standard filters achieve a beta value of 1,000 at 4 µm in the laboratory, this value can collapse to a beta value of just 5 in the field due to vibrations. Our media are designed to remain stable even under pulsation.
- Real contamination: We carry out time-lapse tests with real dusting on our own refueling test stands to better reflect the actual loading behavior than with standardized test dusts (ISO 12103).
Phase 4: Float tests and findings: The final proof is provided by extensive real-world tests on the road with entire vehicle fleets. After use, we examine the filters with regard to their real remaining service life and the actual Water separator at the end of the service interval.
You receive a system whose performance not only exists on paper, but which has been proven to work under the toughest conditions in the field.
