Wiring closet heat loads are rising due to deployment of technologies such as VoIP and Power over Ethernet. Many closets where these technologies are being deployed are not designed with adequate air distribution. The Wiring Closet Ventilation Unit is a rapidly deployable wall or ceiling mounted air distribution and heat removal system designed specifically for the wiring closet environment. By exhausting hot air from the closet to an adjacent space, it allows conditioned air (entering through the Air Intake Grill) to cool the load. This budget conscious unit is an excellent alternative to more expensive air-conditioning systems, providing reliable heat removal with the capability to lower closet temperatures by up to 40ºF (22ºC). If plugged into a UPS, it can also be used as a back-up heat removal system to an already existing air-conditioning unit to maximize system availability in the event of a power failure. Dual fans increase availability while LED status indicators and dry contact outputs enhance the unit’s manageability. Selectable fan speeds allow the user to choose between maximum performances.
