FUEL SEPARATORS
COALESCENCE DEFENSE
Advanced multi-stage coalescence removing free, emulsified and dissolved water from diesel fuel circuits. Anti-corrosion rated to ISO 16332 — the last barrier between contaminated fuel and high-pressure injection systems.
FUEL SEPARATORS — MULTI-STAGE COALESCENCE
Total Water Elimination Before Injection
Water in diesel fuel is not a rare event — it enters through condensation in storage tanks, contaminated deliveries and seal ingress during transport. ELIMFILTERS® fuel separators deploy a three-stage AQUAGUARD™ asset protection system: the first defense layer captures sediment and large contaminants, the second protection stage forces microscopic water droplets to merge and fall into the collection chamber, and the AQUAGUARD™ hydrophobic final barrier blocks any residual water from reaching the injection circuit. ISO 16332 certified — the international standard for diesel fuel water separation performance.

HOW WATER ENTERS THE FUEL CIRCUIT
Entry Points — What ELIMFILTERS® Stops
Tank condensation — temperature cycles cause humid air inside storage tanks to condense directly into the fuel
Contaminated deliveries — bulk diesel transport can introduce water during filling and transfer operations
Biodiesel hygroscopicity — B5 to B20 blends absorb atmospheric moisture more aggressively than pure diesel
Microbial growth — water at the bottom of tanks creates the conditions for diesel bug, generating acid and sludge that clog injectors
Seal ingress — worn tank cap seals and vent lines allow rainwater and wash-down water to enter during vehicle operations
Without Separation — What Happens
Injector tip corrosion — water at high pressure and temperature strips the protective oxide layer from injector nozzles within hours
Injection pump seizure — water breaks the lubricating film between pump plungers and barrels, causing metal-to-metal contact
Cavitation erosion — water vaporizes inside the high-pressure pump, collapsing bubbles that erode pump surfaces
Common rail pressure loss — corroded check valves and seats fail to hold rail pressure, causing misfires and power loss
Cold-weather fuel line freeze — free water freezes in fuel lines at temperatures above the diesel cloud point, blocking fuel flow completely

FREE WATER TO INJECTORS
Hydrophobic final stage blocks residual water from passing into the high-pressure injection circuit
Results verified in heavy transport, marine, power generation and agriculture operations exposed to condensation-prone fuel storage and variable-quality diesel supply.
INDUSTRIAL APPLICATIONS
HEAVY TRANSPORT
Long-haul trucks operating in humid climates and seasonal temperature swings. Eliminates injector corrosion from tank condensation on diesel stored overnight in cold environments.
MARINE
Commercial and fishing vessels. Removes saltwater intrusion and tank condensation from diesel circuits exposed to the highest ambient humidity conditions of any application.
POWER GENERATION
Diesel generator sets with long fuel storage periods. Prevents microbial growth and water accumulation in tanks that sit between infrequent test runs and emergency activation.
MINING
Off-highway haul trucks fueled from remote bulk storage. Guards against water-contaminated fuel from outdoor storage tanks exposed to precipitation and temperature cycling.
AGRICULTURE
Tractors and harvesting equipment fueled from on-farm storage. Protects common rail injection systems from water-contaminated fuel drawn from field tanks after rain events.
CONSTRUCTION
Equipment fueled from portable tanks and on-site bowsers. Intercepts water introduced during fuel transfers and outdoor storage on job sites.
