Wärtsilä Delta cleaner

Compared to traditional cleaning where the charge air cooler has to be removed from the engine, the Wärtsilä Delta cleaner allows the cooler to be cleaned while still in place, allowing for much more frequent cleaning. This helps to maintain the differential pressure (Delta-P) at an optimal level, leading to lower specific fuel oil consumption (SFOC).

With no need to remove the cooler for cleaning, there is no risk of damage during removal or transportation. The cooler is cleaned by injecting foam generated in the cleaning unit. The foam is fed into the cooler via pipes and hoses, penetrating from the inside out. After passing through the cooler fins, the foam turns into a watery liquid that then drains out of the cooler housing. The process takes approximately one hour per cooler, leading to considerable savings in engine down time and service man hours needed for the cleaning.

    • Reduced downtime; the cleaning is easier and faster because the cooler does not need to be detached from the engine.
    • No risk of damaging the cooler during the cleaning.
    • Reduced SFOC because the differential pressure is kept at an optimal level.
    • The same unit can be used on all Wärtsilä engines charge air coolers which are modified to Wärtsilä Delta cleaner operation.
    • The lifetime of the coolers is increased.
    • Reasonable payback time on the investment.

    The Wärtsilä Delta cleaner is an ideal solution for marine and power plant customers operating with Wärtsilä 26, Wärtsilä 32, Wärtsilä 34, Wärtsilä 38, Wärtsilä 46, Wärtsilä 46F, Wärtsilä 50, and ZA40S engines.
