Products against legionella

Legionella is a group of bacteria that can cause Legionnaires’ disease. Legionnaires’ disease is an infectious disease that is similar to pneumonia but is a Pontiac fever. It is transmitted via aerosols by inhalation (drops / water vapor), often from cooling towers, showers, humidifiers, etc. Legionella have the best conditions  between 20 and 50ºC, which means that our lungs provide the best living conditions for further growth. Similar to the temperature in water pipes and the bottom of boilers.

Legionella is found naturally in soil and is therefore a threat everywhere in untreated water. In the consumer network (maine pipeline), there is biofilm that is a breeding ground for bacteria, and even with traditional methods such as hot water rinsing and chlorination of shower heads, you will not get rid of it. TermoRens has since 1994 worked to remove the scale and biofilm the bacteria is living in and eliminate these with Termorens cleaning liquid. The bacteria die after only a short contact with Termorens, but when we use Termorens for remove bacterias we let the liquid stay in the pipes for some hours. This because we then also remove the scale like iron oxide, calcium, biofilm etc. In this way the water pipe also can deliver full pressure again.
