Why Are Open Recirculating Cooling Systems Rethinking Their Legionella Prevention Strategy? Insights from Shanghai ChiMay
The Legionella Challenge in Cooling Towers Open recirculating cooling towers are among the most recognized sources of Legionella pneumophila transmission. The bacterium thrives in warm water—typically between 25°C and 45°C—which makes cooling towers ideal breeding grounds if biological control is inadequate. It colonizes biofilm on heat exchange surfaces, fill media and basin walls, where it…
