A large energy distribution company deployed three JY-DX40 systems across its core-city depot network — inline filtration at the loading pumps, one unified outbound fuel-quality standard. Customer site records report ISO cleanliness improving from 24/22/19 to within 15/13/10.
A large energy distribution company deployed three JY-DX40 systems across its core-city depot network in West Africa — one per depot, installed inline at the loading-pump discharge at 40 m³/h per unit. Customer site monitoring records report ISO cleanliness improving from 24/22/19 to within 15/13/10, with the flowmeter calibration interval extended from quarterly to annually.
A large energy distribution company in West Africa operates multiple core depots across the country's main cities, moving diesel by barge, road tanker and storage transfer. To solve chronic cross-site fuel-quality variation, the company deployed three JY-DX40 high-flow purification systems — one per depot — installed inline at the loading-pump discharge, so that every outbound tanker is filled through the filtration system.
Each unit operates at 40 m³/h, matching single-truck loading peak demand without waiting time. The project objective was strategic as much as technical: "source purification, unified quality across the network" — turning three independent depots into one consistent fuel-quality standard.

The customer distributes diesel nationwide across a long supply chain — barge transfer, road-tanker haulage and repeated tank handling between receipt and dispatch. In such a chain, fuel is exposed to secondary contamination at every stage, and by the time it reaches a depot, its cleanliness depends heavily on which route it travelled.
The country's hot, humid climate compounds the problem: accelerated microbial growth in storage tanks, steadily accumulating particulate and gum. The result was a fuel brand whose quality varied by site — the opposite of what a distribution network promises its customers.
Deploy professional purification equipment simultaneously at three core-city distribution sites — "source purification, unified quality across the entire network."
One JY-DX40 high-flow purification system was installed at each of the three depots, connected inline in series at the loading-pump discharge. Every loading operation now passes fuel through the filtration system before it enters the road tanker — outbound fuel is deep-filtered before it ever leaves the site.
Each unit runs at 40 m³/h — sized to the peak demand of single-truck loading, so purification adds no waiting time to dispatch operations.
The units also operate in dual mode: fixed inline for continuous outbound purification, or temporarily connected to a specific tank for circulation polishing when a problem tank needs recovery treatment — flexible response to sudden quality deviations.
Installing filtration upstream of the flowmeter also protects the metering equipment from particulate wear — addressing pain point 03 at the same time.
The requirement was simultaneously about flow, filtration depth and flexibility — at three separate sites with the same standard.
See the JY-DX40 product page for full technical specifications.
The JY-DX40 uses Jingyuan's rigid composite polymer membrane. The membrane material is inherently oleophilic and hydrophobic — it efficiently intercepts particulate contamination while co-removing trace free water, achieving solid-liquid dual removal in a single pass and keeping outbound fuel clear and bright.
Unlike disposable cartridge media, the membrane is designed for repeated gas-pulse regeneration — restored in place instead of replaced at every clog, with a designed service life of 2–3 years. For a three-site network, this means no continuous cartridge logistics chain between depots.
The membrane filter elements in these three systems have not been replaced since commissioning in 2025 — the units have remained in continuous normal operation on the original membrane sets, maintained through gas-pulse regeneration.
After commissioning, outbound fuel cleanliness was standardised across all three depots. The figures below are drawn from the customer's site monitoring records.
| Indicator | Before (Typical) | After (Reported) | Change |
|---|---|---|---|
| ISO cleanliness code | 24/22/19 | Within 15/13/10 | Far better than industry recommended levels |
| Mechanical debris | Visible rust, hard particles | None | Eliminated |
| Fuel appearance | Cloudy, visible suspended matter | Clear and bright | Significantly improved |
| Flowmeter calibration cycle | Quarterly | Annually | Interval extended 3× |
| Pump & valve failures | Frequent | Markedly reduced | Spare-part cycle extended |

"Deploying the JY-DX40 across our sites was one of the best decisions we made this year. It not only protected our precision pumps and valves — more importantly, it gave our end customers consistently stable fuel quality. Today, our stations are widely recognised locally as the benchmark for high-quality diesel."
— Regional Logistics Manager, large energy distribution company, West Africa
The value of this project is not three separate filters — it is a distributed purification network that turns a quality promise into a verifiable, site-independent standard.
For multi-depot energy enterprises, distributed deployment of JY-DX40 addresses each site's cleanliness problem locally — while delivering network-level value: unified regional quality, lower maintenance cost and higher customer satisfaction.
