At the Gemak stand, two finned coil heat exchangers sit on a white shelf against a blue wall: one with a red-brown coated frame and one with blue fins and copper headers in a galvanised casing. A Gemak product catalogue lies beside them, and a white unit with a hexagonal fan grille, topped by a Eurovent Certified Performance sign, stands to the left.
