For the leak test in vehicle production, large amounts of water are used in a circulatory system in the rain test. The operators of these irrigation systems face a major challenge with water treatment. Common problems are too high a total bacterial count (colony-forming unit, CFU / ml), Legionella in the water or unpleasant smells in the production hall. We have specialized in water disinfection in irrigation systems with our UV disinfection systems and can keep the bacterial count below 8 * 10³KBE / ml in the long term. In addition, we guarantee legionella freedom with our systems.
