Induced Draft Cooling Towers

Induced Draft Cooling Towers

Induced draft cooling tower is also known as mechanical draft cooling tower that use one or more fans to drive or draw air through flowed water. Incoming water is injected throughout the tower with a spray distribution header which is directed downwards in order to maximize the contact of water and air. Since the airflow is counter to the water flow, the coolest water is found at the bottom is in contact with the driest air while the warmest water found near the top of the tower in contact with moist air, resulting in increased heat transfer efficiency.
