The ARTCOOL Slim is a wall-mounted air-conditioner thinner than existing models. Building off the mirror concept of previous ARTCOOL designs, the new design emphasizes the quality and restrained beauty of its materials to make the ARTCOOL Slim appear thinner and more refined. When it is operated, the fascinating dark mirror panel inclines as if the moon moved in the night sky, and the nimble movement of nature is expressed with high-tech elements. A solidness and timeless beauty is conveyed using real glass. The LED display, activated automatically when the ARTCOOL Slim is turned on, smartly expresses the various smart functions.
