A blue "Exstream The Cross-Counterflow" heat exchanger above a louvre damper takes the foreground of the Alfaco and Carel stand. A Carel display headed "Rozwiązania dla spersonalizowanych central wentylacyjnych AHU" shows controllers and sensors, while a coffee bar with high white stools, small fans on the back wall and Gree units complete the red-and-white space.
