WinGD X35-B - Scavenge Air Cooler

5.6.5 Scavenge air cooler
The scavenge air cooler (SAC) decreases the temperature of the hot compressed air from the
turbochargers. This increases the density of the air and thus increases the quantity of air that is
supplied to the cylinders.
The cooling water flows constantly through the tubes of the SAC and flows back to the cooling
water system of the plant.
The SAC has a cover (004, Figure 5-38). For maintenance you can remove the cover.

WinGD recommends to regularly clean the scavenge air coolers, refer to section 9.5 Clean the
scavenge air cooler during operation. This prevents or decreases contamination of the
scavenge air coolers and thus increases the time between overhauls.
