A mechanical draft cooling tower, also known as a mechanical draft tower, is a cooling tower ventilated by wind, which is the main equipment of circulating water evaporative cooling. Mechanical draft cooling tower is widely used in petroleum, chemical, metallurgical and other industries.
The mechanical draft cooling tower includes a bottle type cooling tower, square counter flow cooling tower, square cross flow cooling tower and closed circuit cooling tower.

The natural draft cooling tower makes use of the chimney operation of the cooling tower. The air flow is caused by the temperature difference between the air inside and outside the cooling tower. While mechanical draft cooling towers use fans to make air flow.
The advantages of mechanical draft cooling tower are compact structure, small volume, light weight, convenient installation, not affected by external wind, reliable cooling effect; less loss of cooling water blowing, higher cooling efficiency, high water spraying density, less one-time investment.
The mechanical draft cooling tower uses power-driven fan motors to force or draw air through the tower. Induced draft, a mechanical draft tower with a fan at the discharge at the top, can pull air up through the tower. The fan enables to induce hot moist air out the discharge.
