Case Study
Stage 1 · Customer Problem
ð Customer Problem
A Southeast Asian mining company is located in a remote inland mountainous area within a typical tropical rainforest climate zone, with year-round high temperatures, abundant rainfall, and high humidity. The mine operates a large fleet of heavy machinery for ore extraction and transportation. In the deep mountain mining area, fuel management faces unique environmental challenges:
ð§ïļ
Environmental Humidity Impact
Frequent rainfall and high air humidity in the tropical rainforest affect the stability of fuel stored in tanks, promoting condensation and water ingress.
ðĨ
Accelerated Gum Formation
Under high-temperature conditions, diesel oxidation accelerates, generating large quantities of gums and asphaltenes that clog filters and injector nozzles.
ð
Supply Chain Contamination
Fuel transported over long distances to mountainous areas easily picks up sediment and impurities along the way, arriving already contaminated.
ð°
High Remote Repair Costs
Due to the remote location, once an injector nozzle is damaged, procuring spare parts and transporting them over rugged mountain roads is costly, with long downtime waiting periods.
Stage 2 · Fuel Analysis · NEW
ðŽ Fuel Analysis
Fuel sampling from the mining area's core storage tank revealed contamination levels far exceeding engine manufacturer specifications, with tropical climate conditions accelerating oxidation and microbial growth:
| Metric | Before Treatment | After Treatment | Improvement |
|---|
| ISO 4406 Cleanliness | ~24/22/19 | 12/9/6 | 6-7 levels â |
| Free Water (ppm) | ~320 | âĪ50 | 84% â |
| Visual Appearance | Cloudy, brownish with visible sediment and microbial haze | Clear, bright | â |
| TAN (mgKOH/g) | 0.28 | 0.08 | 71% â |
| Particle Composition | Sediment, mineral particles, gums, microbial debris | âĨ99% removed at âĨ3 Ξm | 99% â |
Values are representative based on tropical rainforest mining site conditions (high temperature, high humidity, remote supply chain). The elevated free water and TAN levels reflect accelerated oxidation and microbial growth under year-round hot, humid conditions. Post-treatment ISO 12/9/6 exceeds typical engine manufacturer requirements (ISO 18/16/13).
Stage 3 · Solution
ð ïļ Solution & System Configuration
The customer installed a JY-T100 diesel purification filter unit next to the core storage tank at the mining area, serving as the last line of defense before fuel enters machinery:
Model
JY-T100 diesel purification filter unit
Membrane
Polymer Rigid Composite, 3 Ξm nominal
Îē Value
âĨ200 at rated pore size
Deployment
Next to core storage tank at mining area
Water Removal
Oleophilic-hydrophobic synergistic separation
Regeneration
Gas-pulse regeneration (brief 5-15 min safety pause)
Function
Gum/sludge interception + particulate + water removal
Monitoring
Differential pressure monitoring
Key design decisions: The JY-T100 was specifically configured with gum-removal filter cartridges to address the fine soft particles generated by high-temperature oxidation in the tropical climate. The large-capacity design reduces the frequency of filter cartridge replacement in the remote region, while the tank-side deployment ensures all diesel dispensed into excavators and trucks passes through purification treatment.

Injector Seizure Reduction
| Metric | Before | After | Improvement |
|---|
| ISO 4406 Cleanliness | ~24/22/19 | 12/9/6 | 6-7 levels â |
| Injector Nozzle Seizure | Frequent occurrences | Substantially reduced | ~75% â |
| Engine Black Smoke | Frequent | Significantly reduced | â |
| Fuel System Failure Rate | High, frequent downtime | Noticeable decrease | â |
| Spare Parts Logistics Cost | Very high (remote mountains) | Significantly reduced | â |
The deployment of the JY-T100 significantly improved the operational condition of the mining area fleet. The previously frequent occurrences of "injector nozzle seizure" and "engine black smoke" were substantially reduced. Maintenance data shows a noticeable decrease in the fuel system failure rate of construction machinery. Clean fuel ensured power output under harsh operating conditions and saved the mining area considerable spare parts logistics costs and downtime losses.
Stage 5 · Lessons Learned · NEW
ðĄ Lessons Learned
â
Key Success Factor
The gum-removal filter cartridge configuration was the critical decision for tropical climates. High temperatures accelerate diesel oxidation, generating gums and asphaltenes that standard filters cannot effectively intercept. The tank-side deployment provides the last line of defense before fuel enters machinery, and the large-capacity design minimizes replacement frequency in the remote mountainous region where logistics are challenging.
â ïļ
Common Pitfall
Tropical rainforest climates accelerate both oxidation and microbial growth in stored diesel. Standard filtration approaches ignore the biological contamination and gum formation that clog filters and cause injector needle valve seizure. Relying on OEM filters alone fails rapidly â they overload with soft gum particles and biological debris, requiring frequent replacement that is extremely costly in remote mountainous locations with weeks-long logistics lead times.
ð
Replication Advice
Directly applicable to all tropical and high-humidity mining operations with remote supply chains. Deploy at the core storage tank for last-line-of-defense protection. The large-capacity configuration is especially valuable where filter cartridge replacement is logistically difficult. For operations with multiple storage tanks, deploy one JY-T100 per tank. The gas-pulse regeneration eliminates consumable dependency entirely.

Customer feedback
Operating in the rainforest means battling high temperatures and impurities. Our diesel used to frequently become cloudy and sticky, causing frequent injector nozzle damage. The JY-T100 effectively solved this problem. It removes gums and impurities, allowing our machinery to run smoothly even deep in the jungle.
