Legionella in your cooling systems: a source of danger

The cooling water used in cooling systems is a breeding ground for bacteria. The temperature of this water at the end of the usage process, is so high that it is ideal for bacterial growth, which is used in cooling process water, and creates an ideal environment for bacteria to grow. In this cooling water, Legionella pneumophila and biofilm are the main concerns. Therefore, effective disinfection is crucial to prevent these problems.

The dangers of Legionella in cooling water

Cooling water is often stored in large tanks, this creates an environment ideal for the growth of Legionella bacteria. The water can become contaminated through the air or during the cooling process, allowing bacteria to grow. Legionella contamination has a number of risks, including:

  • Higher operational costs,
  • Energy and water consumption
  • A shorter lifespan of your machinery
  • Production delays
  • Safety risks

Preventing legionella contamination preventively is extremely important: with correct disinfection, you ensure that the above risks can be avoided. Thus making your production safe.

Risks Biofilm

In cooling systems, biofilm provides an ideal environment for the growth of legionella bacteria. Biofilm is a slimy layer of micro-organisms that can adhere to surfaces, after which these organisms can spread through the system. This can cause infections of various yeasts, fungi and bacteria in the water. Biofilm is very persistent because it attaches to each other with proteins, but removal is very important to maintain clean water.

Desinfection with traditional chemicals

There are a number of problems with traditional chemicals. A product such as hydrogen peroxide is effective for removing microorganisms and biofilm, but can be incorrectly dosed. Underdosing can result in low effectiveness. Overdosage results in unnecessarily high costs and health risks. In addition, conventional disinfectants are a health hazard and there are often strict safety regulations for their use. Unlike these chemicals, Watter's disinfectant is not a CMR substance, so it does not have to comply with strict safety measures during use. In addition, the agent is not included in the hazardous substances list.


The Watter System produces an in-situ disinfectant. As a result, it contributes to reducing CO2 emissions and plastic use. Since the disinfectant is produced on site.

Desinfection with Watter

The Watter system produces a mildly oxidising disinfectant based on electricity, salt and water. This agent is durable, biodegradable and effective in removing various micro-organisms from your water, such as legionella. It is also automatically accurately dosed into your water at a low concentration for effective water disinfection. This means no more constant purchase of expensive chemicals, saving significant costs,
