Anti legionella system

Our Story

With this new approcah we can save:
– time needed to check every pipe periodically
– large quantities of drinking water.

Basic and most ecological weapon to fight against legionella is the heat. We have to consider the following temperatures:

  • 60 to 70 °C (140 to 158 °F) to 80 °C (176 °F) – Disinfection range
  • 66 °C (151 °F) – Legionella dies within 2 minutes
  • 60 °C (140 °F) – Legionella dies within 32 minutes
  • 55 °C (131 °F) – Legionella dies within 5 to 6 hours

Keeping the water temperature outside the ideal range for legionella is an effective control measure for both hot and cold-water systems (Figure 3.3 shows the effects of temperature on survival and growth of Legionella).
Water systems should:
• avoid water temperatures between 25°C and 45°C to prevent Legionella colonization
• maintain cold water below 20°C
• maintain hot water above 50°C.

The majority of conventional anti-legionella systems are focused on water temperature as a way of controlling bacterial growth; by ensuring that water is regularly heated to 60°C you will kill all bacteria lurking in the plumbing (over 90% of Legionella are killed in less then 10 minutes at 60°C and in about one hour at 55°C).

The first step is to make sure that your water reaches this temperature at least once a day, so we advise doing a temperature check (you can find out how to do it here). If you find that water temperatures in your system fluctuate, or you want to be sure that the necessary level is reached each day, there are various systems available to help.

Water can be monitored in real-time with sensors.

We are providing an effective and economic system for preventive solution to Legionnaire disease for Health Establishments (Hospital Centers, Senior Housing) and Public Institutions (Health Centers, Schools…), where regulations demand controling both hot and cold water line at the pipe, we can provide this kind of solution as well.

In the United States, reported cases of Legionnaires’ disease have
increased by nearly four and a half times since 2000.
