Cool-line I available in satin-anodized aluminum and wide variety of unfinished woods, all cool-line products measure 3.5-inch in height, length varies depending on the number of fans. Units are available with 1 or 2 fans and can be mounted horizontally or vertically. The slim, linear styling of the cool-line series makes it ideal for use in commercial, residential A/V and computer installations where quiet cooling is required and space is limited. Powerful but quiet cross-flow fans are used in all models to move air in or out of the enclosure to be ventilated. Temperature controlled and multi-speed, the fans are completely automatic. The aluminum cool-line systems ship configured to exhaust heated air from enclosures but is easily changed in the field for use as intake devices. Wood cool-line versions must be ordered as either intake or exhaust models. Matching grilles both metal and wood are available without fans to trim passive openings. Recognizing the need for cooling products for narrow spaces such as above or below flat-panel displays or mounted on kick panels, we developed the cool-line series of quiet ventilating devices.
