We’ve just completed a total rebuild of this cooling tower at a major hospital.
When we opened the access hatch, the first thing we saw was years of biological growth on the drift eliminators (pictured). This is a perfect place for Legionella bacteria to live and breed.
It was apparent that the access hatch hadn’t been removed for a number of years, and therefore the drift eliminators had not been maintained.
The drift eliminators were replaced as part of the cooling tower rebuilding process, but it is important to consider specialised cooling tower servicing on a once-a-year basis to remove, inspect and clean these critical cooling tower components.
