In industrial fuel management—whether at a high-volume terminal, a remote mining site, or a hyperscale data center—diesel contamination is not an isolated event. It is a cumulative process. Particles are introduced during bulk transfer, while free water and oxidation gums develop during static storage. Relying on a single filtration checkpoint is insufficient for modern high-pressure common rail (HPCR) engines.
To address the full lifecycle of diesel handling, JINGYUAN engineers recommend a two-tier architecture: integrating the JY-DX40 Skid-Mounted System for bulk transfer and the JY-DX5 Modular Unit for continuous tank polishing.
Tier 1: The Gatekeeper (JY-DX40) for Bulk Transfer
When receiving or dispatching fuel, flow rate is critical. Traditional depth filters often cause bottlenecks or succumb to high-pressure bypass, allowing contaminants to pass.
The JY-DX40 is engineered for standard loading arms, operating at a steady 40 m³/h. Instead of disposable fibreglass, it utilizes a Rigid Polymer Composite Membrane.
- Asymmetric Gradient Pores: This structure provides mechanical sieving (down to 2-25µm) alongside surface energy adsorption, capturing soft, oxidized gums that deform and slip through standard media.
- Gas Pulse Regeneration: Operating at low pressure (0.2-0.35 MPa), the system relies on an automated nitrogen or air pulse backwash. This instantly dislodges accumulated dirt, restoring flux without consumable replacements, reducing the Total Cost of Ownership (TCO) by approximately 60%.
Tier 2: The Guardian (JY-DX5) for Static Storage
Once fuel is stored, daily temperature fluctuations inevitably introduce condensation. Micro-water acts as a catalyst for microbial growth and fuel degradation.
The JY-DX5 addresses this through active fuel polishing (tank circulation) at a rate of 5 m³/h (5000 L/h).
- Ambient Temperature Phase Separation: Unlike centrifuges or vacuum dehydrators that require heating—which can thermally degrade diesel—the JY-DX5 utilizes the oleophilic and hydrophobic properties of the rigid membrane. It intercepts free water droplets based on Young-Laplace capillary pressure, achieving ≥99% water removal efficiency at room temperature.
- NAS 6 Cleanliness: Continuous bypass circulation ensures that stored diesel maintains a stable NAS 6 cleanliness level, mitigating the risk of emulsification and injector corrosion.
The Synergy: Comprehensive Fluid Quality Control
By deploying the JY-DX40 at transfer points and the JY-DX5 at storage tanks, operators construct an impenetrable barrier against contamination. This dual approach ensures that fuel is rapidly purified upon entry and continuously maintained during storage. The result is a highly reliable supply chain, reduced hazardous waste (zero disposable cartridges), and optimized performance for sensitive heavy-duty engines.
