Fuels and oils are transported from the refinery to the storage depots by tanker trucks, ships or pipelines. From there it is loaded into another tanker truck and delivered to your site. Every time fuels & oils are transferred from one tank to another, it not only transfers the fuel & oil but also the contaminants present that are deadly to today’s engines.
Many people assume they are buying quality fuel that meets the required specifications; diesel fuel cleanliness is rarely questioned. But higher fuel systems operating pressures, lower system tolerances and tighter filtration have pushed fuel cleanliness into the maintenance spotlight.
Water gets into fuels and oils by adsorption, condensation and human negligence. Dirt and water act as catalysts for the breakdown of fuel via oxidation and by supporting bacterial growth. Although water in fuel or lubricants is often hidden from the naked eye and its inert properties supposedly render it “harmless”, it can be extremely detrimental to most systems.
Fuels typically leave refineries clean, but contamination levels increase throughout the shipment and distribution process. Many contaminated fuel systems are a result of poor handling practices, substandard filtration and aged or inappropriate infrastructures.
