The CleanFactory® app demonstrates how ProfilGate® can be used to systematically control the introduction of dirt via the wheels of industrial trucks and the soles of shoes in industrial environments. The goal is to clearly explain the potential applications of ProfilGate® clean-driving zones and to support decision-making processes. In the day-to-day operations of many companies, it is unclear exactly how contaminants enter sensitive areas. Through an interactive tour of all typical production and logistics areas across various industries, the app highlights these connections.
