Whats the difference between a forced draught and an induced draught cooling tower?

In forced draught design the fan is at low level, takes in ambient air and “pushes” it through the cooling tower. With induced draught design the fan handles saturated air, pulling through the tower and exhausting to atmosphere. The forced draught design offers better access to the fan set (as it is at low level) and to tower internals (clear access via the top of the tower). The fan set is outwith the saturated atmosphere with reduced risk of down time due to motor failure. Direct sunlight entering the basetank can lead to biological growth. The basetank of the forced draught tower is enclosed, preventing the entry of direct sunlight that can lead to biological growth.
