How to prevent Legionella (Legionella pneumophila) formation is a major concern in evaporative cooling systems. In this article, we will explore how to prevent the formation of this dangerous bacteria to human health, providing practical tips and effective solutions to ensure safety and health. Learn how to avoid water stagnation and protect your health with these key strategies.

What is Legionella and why it is dangerous to humans

Legionella is a bacterium that can cause a disease known as Legionnaires’ disease or West Nile fever. This bacterium is transmitted to humans through inhalation of contaminated water droplets, such as those produced by evaporative cooling systems. Legionnaires’ disease can cause pneumonia-like symptoms, such as high fever, dry cough, headache and muscle aches. In more severe forms, the disease can be life-threatening, especially for people who are elderly or have weak immune systems. For this reason, it is important to prevent Legionella buildup in evaporative systems and ensure that they are kept clean and sanitized on a regular basis.

How to Avoid Water Stagnation in Evaporative Systems

To maintain a sanitized and healthy evaporative system, some basic practices must be followed:

  1. Ensure that water in evaporative systems is always moving and does not pool anywhere.
  2. Use an efficient drainage system to remove standing water regularly.
  3. Install a water circulation system that keeps water moving and prevents stagnant areas from forming.
  4. Use a proper filtration system to remove impurities and bacteria from the water.
  5. Keep the evaporative system clean and disinfected regularly

How to prevent Legionella by monitoring water in evaporative systems

To monitor water in evaporative systems, it is important to use appropriate technologies and methods to ensure that it is kept clean and safe. One of the most effective ways to monitor water in evaporative systems is to use a water quality control system that regularly tests for the presence of bacteria and impurities. In addition, level and flow sensors can be used to monitor water movement and ensure that there are no stagnant areas. In addition, it is important to maintain a regular cleaning and disinfection routine to prevent bacterial growth and ensure water safety.

W-CARE the water treatment from W-tech

To effectively prevent scaling or bacterial contamination, W-Tech has developed W-CARE: a broad-spectrum treatment system that acts as both an antiscale and biocide (antialgae and antibacterial).


Trattamento acqua W-tech

We have developed the BASIC, ADVANCED and ADVANCED PLUS systems with which we are able to dose totally organic products that can prevent scale formation and the initiation of corrosive phenomena. They also prevent the occurrence and proliferation of algae and bacteria, which cause silt and mucilage, so as to ensure a sanitized environment, indoor and outdoor.

To complete the range of water treatment systems W-tech also offers W-Purge, a system that automatically manages the purging of the unit ensuring the correct number of cycles of concentration.
