A large multinational enterprise in West Africa deployed six JY-DX5 compact purification units — one per branch — building a "terminal purification barrier" between storage tanks and 200+ vehicles and 50+ generator sets. Customer maintenance records report injector failures down 70% and fuel-related unplanned downtime down 85%.
A large multinational enterprise in West Africa deployed six JY-DX5 compact purification units — one per branch — protecting 200+ heavy trucks and 50+ generator sets. Customer maintenance records report injector failures down 70%, fuel-related unplanned downtime down 85%, onboard filter element life extended from roughly 3 months to 7.5 months, and annual consumables cost down approximately 60%.
A large multinational enterprise in West Africa — active in energy, transport and communications — operates six branch companies across different provinces, running a fleet of 200+ heavy trucks and engineering vehicles and 50+ large diesel generator sets, each branch with its own storage tanks.
The company imported six JY-DX5 compact diesel purification units, one per branch, to build a "terminal purification barrier" — storage-tank circulation polishing plus pre-fueling filtration — so that every drop of diesel entering an engine or generator meets one standard, regardless of which of the ten-plus local suppliers it came from.

| Core Element | Jingyuan rigid composite polymer membrane (micron-scale) |
| Result Source | Customer branch maintenance records |
The company is managed centrally from headquarters but operated locally by each branch. Because the branches sit in remote regions, each independently procures diesel — from more than ten different suppliers, with wildly varying quality.
For headquarters, this created a systemic management blind spot: no unified fuel-quality standard, no common purification procedure, and no way to monitor the real cleanliness of fuel at each branch. Vehicle and generator reliability varied site by site — and nobody at headquarters could see why.
One fuel-quality standard across all six branches — protecting 200+ vehicles and 50+ generators with equipment that local staff can operate themselves.
Six JY-DX5 units — one per branch — establishing a clean-fuel barrier between each branch's storage tanks and its end equipment.
Each unit performs storage-tank circulation polishing on the branch's tank inventory and pre-fueling filtration at the point of dispensing — two layers of defence at each site.

After the distributed deployment, the enterprise unified its energy-quality standard group-wide. Figures below are drawn from the customer's branch maintenance records.
| Indicator | Before (Typical) | After (Reported) | Change |
|---|---|---|---|
| Mechanical debris | Visible impurities, heavy particulate | Eliminated | Reported 100% removed |
| Free water | Trace free water present | Removed | Reported 100% removed |
| Fuel appearance | Cloudy, visible suspended matter | Clear and bright | Significantly improved |
| Injector failures | Frequent — several per month | Markedly reduced | Failure rate ↓70% |
| Generator downtime (fuel-related) | Occasional unplanned stops | Near-eliminated | Stops ↓85% |
| Onboard filter element life | ~3-month replacement cycle | ~7.5-month cycle | Life ×2.5 |
| Annual consumables cost | Baseline | Reduced | Cost ↓~60% |
Data note: values on this page are drawn from the customer's branch maintenance records for this project (Case DS17, updated 2025) and are presented as reported. They describe this deployment and are not a general performance guarantee — actual results depend on fuel condition, contamination load and site configuration.
"We used to spend our time chasing mechanical failures across regional branches — then we found the root cause was diesel quality. The JY-DX5 is a very practical solution — moderate footprint, reliable performance. After equipping all six branches, fuel-related downtime complaints dropped sharply, and management became far easier."
— Director of Asset & Equipment Management, large enterprise, West Africa
The value of this project is a group-level transformation: fuel quality moved from an unmonitored variable to a managed, standardised asset.
JY-DX5 — every drop of diesel entering an engine passes a standardised purification step, wherever the branch, whatever the supplier.
