Cooling Tower Cleaning

Cooling towers provide an ideal environment for the growth and incubation of many organisms, including the Legionella bacteria. Periods of non-use (winter lay-up) exacerbate the problem. Although a consistent biocide program can reduce the risks, it is best practice to clean a cooling tower at least twice a year. According to The United States Occupational Safety and Health Administration’s (OSHA) Technical Manual, all cooling towers should be thoroughly disinfected at a minimum of twice per year. “Cooling towers should be cleaned and disinfected at least twice a year.
