Water attractions are an important part of Europa-Park. Of course, the regular cleaning of the water is fundamental. Due to the the size of the park, individual and sometimes widely scattered filter systems are required. In addition, cleaning is carried out partly manually, partly automatically. The operation of the systems is often complex. Here, the two smart actuators simplify the interaction between personnel and actuator immensely. Thanks to simple and intuitive operation, employees are guided through the Smart Actuator app. In this way, even first-time users can quickly and efficiently read out the operating status and cycles directly on site. This ensures increased transparency and security.
