Traditional diesel polishing relies on disposable filter elements and coalescers that load up, blind, and get thrown away. The CIS rigid composite polymer membrane is regenerated through the designed backwash procedure — so the operating cost shifts from consumables to a little electricity.
Every claim here is traceable to the published datasheet (DS-FUEL-EN, Rev.01). Figures describe the Jingyuan skid-mounted lineup, 5–60 m³/h.
| Dimension | Traditional cartridge / coalescer | Jingyuan CIS membrane |
|---|---|---|
| Particle capture | Strong when fresh; degrades as the element loads | ≥98% @ ≥5 µm, stable via regeneration |
| Free-water removal | Needs a separate coalescer stage; element-dependent | ≥95% free water, no separate stage |
| Sludge / microbial load | Blinds elements quickly → frequent change-outs | Gas-pulse clears the surface; no blind-up |
| Consumables | Recurring cartridge purchases | No disposable cartridges |
| Regeneration | Manual element swap — labor and downtime | 30-second gas-pulse, automatic |
| Service life | Per change-out (weeks–months) | Membrane core 2–3 years |
| Hazardous waste | Spent cartridges (oily waste stream) | Minimal — no element disposal |
| Operating cost profile | Consumable-dominated, scales with use | Energy-dominated, low and predictable |
| Explosion-proof option | Varies by build | Explosion-proof configuration available (JY-Q325 and JY-DX40 standard) |
Stored fuel is the hardest duty for a consumable element — here is what actually happens in the field.
Buy, install, load, blind, discard — a recurring consumable loop with labor and disposal cost.
Contaminants are separated at the rigid membrane; a gas pulse restores flux in 30 seconds.
Over 2–3 years the membrane core replaces dozens of cartridge change-outs.
A mid-size tank farm illustration — 500 m³ processed / month, 12 cartridge changes / year. Event counts illustrate the structure; your own numbers come from the lifecycle assessment.
| Cost Line | Traditional — 3 yr | Jingyuan — 3 yr |
|---|---|---|
| Consumables | 36 change-outs × cartridge sets | No cartridges |
| Labor & downtime | 36 change-out events | None — automatic 30 s regeneration |
| Hazardous disposal | 36 oily waste element sets | Minimal |
| Energy | Comparable pumping duty (omitted) | Membrane regeneration electricity |
| Membrane refresh | — | 1 core at 2–3 yr design life |
| Cost structure | Consumable-dominated — grows with contamination load | Not consumable-dominated — refresh quoted per project |
We deliberately do not publish a generic dollar total or savings percentage — those depend on your local cartridge prices, labor rates and disposal costs. Assess your own duty in the Lifecycle Cost Assessment or request a project-specific figure. The structural point stands: a cartridge program's cost scales with contamination load; a membrane system's does not.
We manufacture membrane systems — and we still tell you where a consumable approach is the reasonable choice.
The membrane elements have a designed service life of 2–3 years. Within that life they are regenerated in place by gas pulse rather than replaced at every clog like a cartridge; at end of service life the membrane core is replaced — a planned, infrequent maintenance event rather than a recurring consumable stream.
A short pulse of clean compressed air (external 0.5–0.7 MPa source) clears the membrane surface — no hot water, chemicals or solvents.
Yes. There is no element to stock, ship to a remote site, or fit under time pressure — a meaningful advantage for mining and marine duty.
Capex is typically higher than a bare cartridge housing; the payback comes from eliminating the consumable, labor and disposal stream. Most duty cycles recover the difference within the first membrane service life — assess yours in the Lifecycle Cost Assessment.
In most migrations, yes. Skid interfaces follow standard flange sizes (e.g. DN100 PN16 on the DL60), and much of the existing pump and piping is retained — the skid drops into the tank circulation loop.
Media boundary: diesel with flash point ≥38 °C — gasoline is strictly prohibited (DX5 additionally handles kerosene, hydraulic and turbine oil). Dissolved water is not removed; free and emulsified water (≥95%) is the design target.
