Forced Draught Cooler

A forced draught cooler has a mechanical draft tower with a blower type fan at the intake. The fan forces air into the tubes of the cooler, creating high entering and low exiting air velocities. The low exiting velocity is much more susceptible to recirculation. The benefit of the forced draft design is its ability to work with high static pressure. Such setups can be installed in more-confined spaces and even in some indoor situations.
