KLEENFUEL ELAIS

CASE STUDY ELAIS FUEL CLEANING AT DARRINGTON QUARRIES

BACKGROUND

Darrington Quarries operates heavy machinery, including a CAT Loader, under tough quarry conditions. Contaminated diesel fuel is a frequent issue in such environments due to bulk storage, dust ingress, and tank ageing. This contamination leads to: Higher particulate levels in fuel. Water contamination , promoting corrosion and microbial growth. Increased engine wear and unplanned downtime. Shortened life of exhaust after-treatment systems such as EGR, SCR, and DPF. To address these challenges, Kleenoil deployed its KleenFuel ELAIS system on the CAT Loader to continuously polish diesel fuel and achieve ISO cleanliness targets.

THE CHALLENGE

Diesel fuel supplied and stored on site was found at ISO 21/20/18 – significantly dirtier than OEM requirements. High particle counts:

o 4 μm = 16,040 o 6 μm = 7,390 o 14 μm = 1,376.

Dissolved water content = 41 ppm, increasing risk of injector damage & microbial contamination. Clean fuel needed to meet or exceed ISO 18/16/13, the standard for protecting highpressure common-rail engines.
