In the foreground of the Wanas stand, a black heat recovery unit stands with its front cover removed to reveal the heat exchanger and internal compartments, topped by a wall controller and Wanas-branded balloons. Further back, a white unit with green spigots and the "Strefowa wentylacja" graphic draw visitors to the counter.
