Indonesian Mining Site Multiple 40m³/h High-Flow Diesel Purification Systems

The customer is a large-scale open-pit coal mine operator in a region of Indonesia. The site has hundreds of heavy-duty dump trucks, large excavators, and high-power generator sets, with a large daily diesel consumption.

Before introducing the purification system, the mining area faced fuel quality issues specific to tropical conditions:

Impurity contamination and microbial risk: Indonesia's high air humidity causes storage tanks to easily generate trace free water. Diesel mixed with bio-components is prone to breeding "oil slime," causing frequent cartridge blockage.

Extreme dust environment: The open-pit mining area has severe dust. Fine, hard mineral powder entering the diesel system causes abrasive wear on the precision components of the HPCR system.

High-frequency downtime repairs: Previously, mining trucks frequently experienced insufficient power and injector seizure, with unplanned downtime causing significant output losses.

Contamination indicator exceedance: The original fuel particle count fluctuated around ISO 24/22/19, exceeding the target range.

The customer configured multiple JY-DX40 industrial-grade purification arrays at the mining area's main fuel depot:

Polymer Rigid Composite Membrane: Using Jingyuan® polymer rigid composite membrane, leveraging the oleophilic-hydrophobic properties of the membrane material, it efficiently intercepts particulate impurities while synergistically removing trace free water, ensuring dispatched fuel is clear, transparent, and meets cleanliness standards.

Deep filtration: Specially customized polymer deep filter material performs staged interception of gums and fine mineral powder specific to Indonesian B35 biodiesel.

Continuous monitoring: The system is equipped with real-time particle count monitoring and differential pressure early warning, ensuring the filtered fuel meets the standards required by the engine manufacturer.

By deploying multiple JY-DX40 units, the mining area effectively resolved the fuel quality challenges that had plagued it for years. The purified diesel particle count is stably maintained at ISO 15/13/10. The injector life of heavy-duty trucks has been effectively extended. Due to improved fuel quality, engine combustion is more complete, and per-unit fuel consumption has also been reduced.
