Cleaning, rinsing, cooling - water is an important component in many processes in paint shops. For example, the ventilation systems with air humidification for spray booths require clean water.
For employees, it is even more important that process water is not contaminated with legionella and other dangerous germs. Usually, such process water is stored in water basins, cooling water tanks or holding tanks. In the tanks and line pipes, the water must remain germ-free and clean to protect employees until it is used.
