Cool-Rack is a freestanding, refrigerated IT rack system that neither emits heat nor generates annoying noise in the room. Cool-Rack is designed for deployment directly in the office and in equipment rooms. A water-powered refrigeration unit is integrated in the upper part of the rack. The innovative and energy-efficient cooling takes place in a closed circuit. The thermal loads of the IT components are thus directly eliminated at source and do not find their way into the room.
