Water Conservation: The biggest advantage of a dry cooler is that it does not use water to dissipate heat, so it has significant environmental advantages in water-stressed areas. In contrast, wet-cooling systems rely on large amounts of water to cool the genset by evaporating the water, and therefore consume more water, which can be a constraint, especially in arid regions.

Lower efficiency: The cooling efficiency of a dry cooler is dependent on the air temperature and is therefore significantly lower than that of a wet cooling system in high temperature environments. Wet cooling systems can quickly remove heat through the evaporation effect of water, even in high-temperature environments can maintain a high cooling efficiency.
