Modernizing Tower Airflow

Retrofit Fan Systems for Existing Cooling Towers

Cooling towers depend on consistent airflow to reject heat effectively. When a tower's original fan system ages, requires excessive maintenance, or no longer suits current operating needs, a modular fan retrofit can restore reliable airflow generation within the existing tower structure.

Fan systems for cooling tower applications are engineered around the physical constraints of the tower, the airflow requirements of the site, and the facility's control and redundancy goals.

Design Considerations

Benefits to Evaluate in a Modular Fan Retrofit

The right configuration depends on the tower design and project goals. Considerations commonly evaluated include:

Modular Installation

Multiple smaller fans can be installed within the existing tower footprint in place of a single large fan assembly.

Multiple-Fan Configurations

Distributing airflow generation across several fans rather than relying on one unit for the entire tower cell.

Improved Serviceability

Depending on design, individual fans may be accessible for maintenance without taking the full tower cell offline.

Control Flexibility

Fan systems can be configured with controls supporting coordinated operation across the tower.

Redundancy Options

Where specified, multi-fan configurations can be designed with redundancy considerations appropriate to the application.

Retrofit Flexibility

Configurations can be developed to match the mechanical and structural constraints of the existing tower.

Variable-Speed Operation

Where supported by the selected equipment, variable-speed control can adjust fan output to match cooling demand.
