How Often Should Cooling Towers be Cleaned?

Cooling towers should be cleaned regularly; any time they have been in a low-use state, such as during the winter, they should be thoroughly cleaned and maintained before starting up again. Additionally, towers that continue to struggle with microbial growth should be cleaned more often.

We recommend cleaning at least twice a year, with particular attention to spring cleaning after the long winter lapse in usage.

However, for the safest operation, many businesses and facilities opt to have their cooling towers cleaned every quarter to ensure that potentially fatal illnesses resulting from Legionella do not arise.

The cost of more frequent cleanings is offset by the monetary savings in energy bills and the lack of any need to replace the cooling tower equipment due to preventable failure.
