A pre-chill system for reducing the temperature of air entering a cooling system includes a wicking material sheet and a series of frame segments. The frame segments are operable to secure the wicking material sheet to an outer casing of the cooling system in a path along which air enters the cooling system, each of the series of frame segments including one or more magnets magnetically attachable to the cooling system. A misting system is capable of directing moisture adjacent an outer face of the wicking material sheet. The frame segments are magnetically attachable to the outer casing of the cooling system over the wicking material sheet so as to retain the wicking material sheet against the outer casing with the wicking material sheet held between the frame segments and the outer casing.
