Deoxidization anti-rusting. Corrosion can be inhibited by reducing dissolved oxygen. The amount of oxygen dissolved in the water depends on the temperature and the partial pressure of oxygen in the air contacting with the water. Cooling water usually contains dissolved oxygen with the concentration close to saturation even in a closed system.
