What is domestic hot water and cooling tower water?<\/strong><\/h2>\n\n\n\n

Domestic Hot Water (DHW)<\/strong> refers to heated water intended for domestic or hygiene use (showers, sinks, washbasins). Due to its temperature and its passage through sometimes complex networks, it can promote the development of biofilms and micro-organisms such as Legionella<\/strong>, requiring regular monitoring.<\/p>\n\n\n\n

Cooling tower water<\/strong> is used in industrial or commercial cooling installations to dissipate heat from processes or equipment. Their open-circuit operation promotes exchanges with the air, creating conditions favourable to bacterial growth, particularly Legionella<\/strong>, which can be dispersed as aerosols.<\/p>\n\n\n\n

Domestic hot water and cooling tower water are both subject to strict regulations to prevent health risks and protect building occupants, workers and the public.<\/p>\n\n\n\n

There are several key points of vigilance:<\/p>\n\n\n\n
