A condenser is a heat exchanger used to remove heat from refrigerant vapor and convert it into liquid.
Water cooled condensers use water to absorb this heat — examples include double tube, shell and coil, and shell and tube condensers.
An evaporative condenser is different because it combines air and water for cooling.
In an evaporative condenser, the refrigerant is cooled by evaporating water and the airflow — not just by circulating water.
Therefore, an evaporative condenser is not purely water cooled, so it is the correct answer.
