Total Cost of Ownership Efficiency Increases the capacity of the air conditioner by supplying a warmer return air temperature. Active Airflow Control Monitors and actively adjust cooling unit airflow in containment systems, while providing visibility to effective cooling to critical IT equipment. EcoLEDgy Driven Lighting Integrated high efficiency LED lighting with on/off motion sensors Adaptability Modular strategy Modular design of the mechanical and control systems allow for gradual build-up of the cooling infrastructure to match the cooling demand of the facility. This greatly reduces CAPEX expeditures and provides deferred investment throughout the life of the facility. Flexibility Support for varying aisle widths, rack heights, rack depths, and single rows. Supports hot and cold aisle containment Air Return System Centralized hot air return system for room and external air handling systems minimize obstruction of lighting into the aisle and provide cable access from within the contained aisle. Availability Over Aisle Access Tooless removal of individual panels to allow access above the aisle for cabling and maintenance Scalable densities Allows for higher densities to be achieved by integrating containment with room, row and rack cooling system architectures. Agility One-way locking door Secures the hot aisle while allowing for quick exit in case of emergency. Safe Slide Doors Emergency break away sliding door enables quick exit in the event of an emergency Ceiling tiles Closes off the top of the aisle to prevent mixing of the hot and cold airstreams in the IT environment. Modular design Modular design provides scalable solutions to add cooling as demand increases. Fire Safe System Alerts personnel and drops ceiling panels based on temperature to enable fire suppressions system in the room to extinguish the fire. UL723s listed.
