Engineering Principle
Staged separation, droplet coalescence, gravity collection, and a hydrophobic barrier remove water while supporting particulate control.
Water contamination in fuel systems operates across three phases: free water that settles and can be drained, emulsified water suspended in micro-droplets that conventional filters cannot intercept, and dissolved water that forms free phase when temperature changes. Each phase causes a different failure mode - microbial growth, injector corrosion, and cavitation erosion respectively.
HYDROCORE™ hydrophobic technology addresses all three phases through a sequenced interception architecture where each protection layer is engineered for a specific water contamination state. The result is 99.8% water separation efficiency - validated across the full operating temperature and fuel flow range.
Water in the fuel system does not cause a single catastrophic failure - it degrades the injection circuit progressively. Microbial colonies form at the water-fuel interface, producing acids and biomass that contaminate the entire fuel supply. Injector corrosion from water contact is cumulative. Each hour of operation with water present removes service life that cannot be recovered.

HYDROCORE™ - WATER SEPARATION PROTECTION TECHNOLOGY
“Water intrusion was destroying our injection pumps on a predictable seasonal cycle. HYDROCORE™ hydrophobic separation eliminated that cycle entirely - our last two maintenance inspections showed dry sumps across every test unit.”
HYDROCORE™ water separation technology protects any fuel system where water ingress threatens injection system integrity.
Long-haul diesel drawn from shared depot storage tanks accumulates water from condensation cycles across the supply chain. Diesel stored below 15 deg C can hold water in solution that precipitates as visible free water only after the fuel warms up inside the vehicle tank - arriving at the injectors in a condition that visual inspection at the depot would not have detected.
A 10,000-litre genset fuel tank exposed to seasonal temperature cycling accumulates significant free water at the bottom draw point over a winter storage period. When the genset starts under emergency load, the first fuel drawn carries the accumulated contamination from months of static storage - the worst-case fuel quality event delivered at the worst-case timing.
On-farm diesel tanks in above-ground installations undergo diurnal temperature swings through growing seasons. Each cooling cycle draws humid ambient air through tank breathers, depositing condensation on tank walls. This water collects at the bottom draw point and concentrates progressively through the season without any external indication.
Marine fuel tanks breathe salt-laden humid air with every sea temperature cycle. Condensation from this air carries dissolved salt that does not evaporate when water settles - creating a brine layer at the tank bottom that is more corrosive to injection components than fresh water contamination from land-based storage.
Bulk fuel deliveries to remote sites arrive after long-distance road transport. Vibration during transit re-emulsifies settled water back into suspension, delivering fine water droplets uniformly dispersed through the fuel - the condition least visible on inspection and most damaging to injection system tolerances.
Mobile refueling bowsers on active sites are exposed to rain and humidity during every fueling operation. Water enters through loose filler caps, outdoor drum transfers and bowser condensation. On sites where multiple bowsers and operators share refueling duties, there is no consistent quality control over the condition of the fuel reaching each machine.
