Protect your cooling towers against corrosion, scaling and bacterial growth



Spring is a critical time for cooling towers; those that have been operating throughout the winter need to be cleaned and disinfected before the hot season, just like seasonal towers that restart for the summer season. Our laboratory observations show that 25% of towers that have not undergone spring disinfection are at risk of having high counts of Legionella pneumophila bacteria (legionella) during the season. Warmer temperatures can lead to an increase in water demand for cooling. If the water used is not properly treated, it can cause damage to internal components of the tower, such as cooling fins and heat exchangers. That's why it's essential to ensure that the water in cooling towers is properly treated before restarting.


Water treatment for a tower aims to protect systems against corrosion, scaling, and bacterial proliferation such as legionella. This bacterium, transmitted through contaminated water droplets, can be deadly in some cases. In Quebec and some US states, the cooling tower maintenance program must include these steps to minimize its proliferation:


  1. Cleaning

  2. Disinfection

  3. Protection program

  4. Monitoring and documentation


At Magnus, our program, which includes several steps such as filtration, neutralization, and disinfection, helps reduce potentially harmful impurities and contaminants to enable optimal cooling system operation and prolong the lifespan of its components.


As a recognized leader in water treatment for cooling towers, Magnus offers reliable, effective, environmentally low-impact solutions that bring significant water reductions. With in-depth expertise and advanced technology, Magnus is a smart choice for managers and owners concerned with protecting their investment while ensuring the safety of the water used.
