If your cooling tower is dirty, 1) you are literally paying the price for lack of maintenance – the dirt affects your system performance and increases energy consumption, and 2) you are risking the building occupants’ health.
Spring is coming, and sooner than later you will have to start up your cooling tower again. If you have worked on a season lay-up or storage inhibitors, your job will be easier. But most of us get so involved in cleaning, repairing or replacing chillers that forget about the importance of maintaining the cooling tower in the cold season. If that is the case, your startup process will need more attention.
