source site A disease can be caused by the bacterium Legionella pneumophila, which is also known as legionnaire’s disease. This disease is a serious pulmonary infection. It multiplies in the water systems with the temperature between 20ºC and 45ºC. Hence, these systems, along with whirl pool and air conditioning are usually contaminated without cooling tower disinfection. The droplets containing this bacterium when inhaled, can possibly cause lethal infection.
http://sodermpc.com/patient-information/scheduling/ Concerning the protection of public from omnipresence of Legionella in surface water disease, cooling tower disinfection has become a necessity.
Therefore, consider Chloramine-T to be your first choice for disinfecting cooling towers against Legionella pneumophil. The solution of chloramine-t is non-corrosive against materials, practised for routine applications and/or emergency treatment and effective to fight bacterium.
