At aquanale 2019, ProMinent's stand showed how swimming pool operators can ensure clear, pure swimming pool water with energy-saving and environmentally-sound solutions. “All in all, a successful, international exhibition. We are very happy!" said Harald Jarc, Managing Director of ProMinent Deutschland GmbH, of aquanale in Cologne, which attracted a large number of visitors. He added: "At this year's trade fair, we entered into a lot of quality discussions with existing and potential customers from Germany and abroad. On the first day of the event, a lot of people were drawn to our stand by the presence of Sarah Köhler, World Champion in the 1500 m freestyle. The friendly swimmer from Heidelberg signed give-aways and chatted to existing customers and potential customers about water quality and how it impacts on performance, success and health.”
