Winning the War Against Water

Combination of Causes

Maintaining dry fuel has become more important – and more challenging – in recent years due to an untimely convergence of factors:

• Ultra-low-sulfer diesel (ULSD) requires additives to meet lubricity specifications which make it harder to remove water from the fuel
• Many states require increased use of biodiesel blends which can hold up to 10-25x more water than traditional diesel fuel
• The injectors in today’s complex high-pressure common-rail systems (HPCR) are more susceptible to premature wear and damage from water

Water has been shown to cause up to 30% of HPCR system failures. And when combined with the variability of fuel sources and the high levels of ambient water diesel fuel is regularly exposed to, it has quickly become a major problem for equipment manufacturers, owners, and fleet managers.

Countering with Coalescing

To help address these challenges, Donaldson created Synteq™ DRY, an advanced, multi-stage coalescing technology that delivers industry-leading fuel water separation for greater protection.

Specifically designed to work with today’s ULSD and biodiesel blends, Synteq DRY:

• Removes 80-90% more water from fuel over the life of the filter – significantly more than standard filters and other coalescing filters in the market
• Is highly resistant to degradation from contaminants even when fouled
• Retains its performance and efficiency throughout the life of the filter — even in the most challenging operating conditions

With a typical injector repair costing around US $1,200 and a pump repair around US $2,200, industry-leading water removal efficiency is a sound investment. Drier fuel can help extend the life of your equipment, keep your operation running, and save you money.
