Construction
Fuel filtration for excavators, loaders, graders, cranes, compressors and temporary site fueling systems.
Cleaner DieselRemoves water, solids and contaminants before fuel reaches engines.
Heavy-Duty UseBuilt for construction, mining, rail, fleet and industrial fuel systems.
Lower DowntimeProtects pumps, injectors, filters and downstream components.
Custom VesselsConfigured around flow rate, pressure, fuel quality target and site layout.
Clean fuel for demanding applications.
Stored diesel can collect dirt, free water, emulsified water and biological growth over time. Lemico filtration vessels help remove contamination before it reaches engines, helping equipment run reliably in harsh operating conditions.
Built around your fuel system.
Systems can be reviewed for bulk storage tanks, day tanks, transfer skids, fueling stations, mobile service units and industrial diesel supply packages.
Clean Diesel
Three ways to protect stored diesel
Lemico supports clean diesel systems with equipment selected around how contamination is controlled in the field, not just how it is filtered once damage has already started.
- Particulate filtration housings and skids: filtration for dirt, rust, tank debris and fine solids in storage, transfer and fueling systems.
- Particulate and water removal fuel conditioning: filtration and conditioning packages for removing solids and water before fuel reaches engines or day tanks.
- Particulate and water prevention fuel monitoring: monitoring and maintenance support to help identify contamination issues early and keep stored diesel in better condition.
Industries Served
Diesel filtration packages are useful anywhere stored fuel quality affects uptime, service cost and equipment life.
Mining
Heavy-duty filtration for haul trucks, drills, generators, crushers and remote fuel storage applications.
Rail
Diesel filtration support for rail fueling yards, storage tanks, transfer points and locomotive service operations.
Industrial Fleets
Fuel quality systems for truck fleets, municipal yards, ports, terminals and maintenance facilities.
Power Generation
Stored fuel filtration for standby generators, prime power packages and mission-critical diesel systems.
Bulk Fuel Storage
Filtration vessels for tank farms, transfer skids and diesel polishing systems.
Contaminants Removed
Diesel filtration systems can be configured to address the contamination risks most likely to damage equipment.
Particulate
Fine solids, rust, dirt and tank debris that can damage pumps, injectors and metering equipment.
Free Water
Water removal helps reduce corrosion, microbial activity and downstream filter plugging.
Emulsified Water
Coalescing options can help separate small water droplets where fuel condition requires it.
Microbial Contamination
Fuel polishing and filtration can help reduce sludge and biological contamination created by water in storage tanks.
Sludge & Sediment
Filtration can help remove settled contamination disturbed during transfer, recirculation or tank cleaning.
Fuel Quality Drift
Recirculation and polishing systems help maintain stored diesel quality between deliveries and equipment use.
Why Stored Diesel Needs Filtration
Contamination often enters diesel before it ever reaches the machine: during transport, tank storage, transfer or dispensing.
Modern Fuel Systems
Tight-tolerance injectors and pumps are sensitive to fine particles and trace water that can reduce pressure, disrupt spray patterns and increase wear.
Fuel-Water Interface
Microbial growth develops where water and diesel meet, creating sludge, acids and biofilm that can plug filters and corrode tanks.
Temperature Swings
Changing temperatures can create condensation in tanks, increasing free water and making microbial growth more likely.
Biodiesel Blends
Some diesel blends can hold more water than conventional diesel, increasing the importance of water control and routine filtration.
Before the Engine
Bulk filtration and polishing condition the fuel before it reaches on-equipment filters, helping reduce emergency filter plugging.
Ongoing Stability
Continuous or scheduled recirculation helps keep stored fuel clean and dry between deliveries and equipment use.
Filtration Vessel Options
Vessel type is selected around diesel condition, required cleanliness, flow rate and maintenance preference.
Particulate Filter Housings
Cartridge or bag filter housings for removing solids from diesel transfer, storage and polishing systems.
Water Separation Housings
Coalescer and separator arrangements for reducing free water and protecting downstream equipment.
Fuel Polishing Packages
Recirculation and filtration packages for maintaining stored diesel in tanks, yards and generator systems.
System Benefits
Clean diesel helps protect equipment uptime and reduce hidden maintenance costs across the fleet.
Protects Engines
Cleaner fuel helps protect injectors, fuel pumps and high-pressure common rail systems.
Extends Component Life
Reducing abrasive particulate and water contamination helps reduce wear on downstream components.
Reduces Filter Plugging
Bulk filtration can reduce the contamination burden on equipment-mounted filters.
Lowers Maintenance Cost
Cleaner fuel can reduce emergency service events, filter change frequency and fuel-system troubleshooting.
Improves Reliability
Consistent fuel quality supports reliable starts, steady operation and fewer contamination-related failures.
Supports Harsh Sites
Systems can be configured for outdoor yards, remote sites, mine environments and high-use industrial facilities.
Accessories & Documentation
Diesel filtration vessels can be supplied with the accessories and submittals needed for a clean installation.
DP Gauges
Differential pressure gauges or indicators for monitoring element loading and maintenance timing.
Vents & Drains
Vent, drain and sump arrangements for service, inspection and water removal.
Relief Valves
Pressure relief valve options based on vessel design pressure and system requirements.
Sampling Points
Sample points can support fuel quality checks before and after filtration.
Spare Elements
Spare cartridge, coalescer, separator or bag filter elements can be included for startup and maintenance.
QC Package
Drawings, calculations, material records, inspection documents and project data books can be supplied where required.
