With 12,000BTU of cooling power, the 120V, 60 Hz SRCOOL12K is ideal for use in data centers, server and wiring closets, IT environments, home and small business offices, conference rooms, warehouses, entertainment centers or other venues with heat-sensitive equipment, particularly in areas that facility air conditioning can't reach. The SRCOOL12K not only adjusts ambient room temperatures, but can also dehumidify and filter the air, providing better air quality for enhanced equipment performance with minimal noise and power consumption.The SRCOOL12K has a built-in evaporator that expels the condensed water through the exhaust duct, so there is no need for a drain tube, drain pan or water collection tank. Both a standard louvered vent (for general room cooling) and a directional ducted cooling vent (to direct cold air where most needed) are provided. A directional exhaust duct safely removes hot air from the room. SRCOOL12K comes equipped with an auto-restart feature that retains all system settings and returns the unit back to its last operational state after AC power is restored. A built-in timer enables the unit to be programmed for unattended start-up and shutdown. Controls and displays are conveniently mounted on the top panel. With the optional added accessory of the SRCOOLNET, this communication port allows users to monitor temperatures, receive alerts, review logs and control settings from any location. Designed for quick and simple installation, the SRCOOL12K rolls into place on built-in casters and plugs into a standard 5-15R outlet with no adapter required. An included window/drop ceiling kit provides multiple installation options.The SRCOOL12K uses environmentally friendly R410a refrigerant, which complies with EPA standards for 2010 and beyond, and is accepted worldwide.
