Introduction

The long term shutdown of a cooling water tower involves measures to preserve the structure itself, electrical systems and mechanical components.  The tower will be exposed to extremes of the environment and unless these components are protected there may be problems when it comes to re-commission a cooling tower which can result in delays and unexpected costs.

Tower Structure

Mechanical Components

Mechanical components should be protected from internal moisture, rust and corrosion.  Consideration should be given to off-tower storage of mechanical components in a building to protect them from exposure to the outside environment.   Re-installation should be delayed as long as possible.  The following actions should be considered to protect mechanical components:
