A blue display column holds a vertical row of radial fans labelled with "ECblue" designations, beside a central panel headed "ZAvblue" and a second column with further fan modules. A panel on the right carries German text ending "für Wärmepumpen", about fans for heat pumps, while staff talk with visitors.
