Cream-coloured Petra air handling units with access doors, inspection windows and a mounted control panel stand on a red carpet strip. Tall white gate frames with blue tops and red-and-blue Petra logos frame the display, and a roll-up banner presents the "Petra Green Variable Water Volume System" beside a large island photograph.
