◾ Space-saving installation of the internal unit between the 482.6 mm (19") level and side panel
◾ External unit is sited outside the building
◾ Maximum energy efficiency by cooling the individual rack, rather than the whole room
◾ Efficient operation thanks to EC fan technology
◾ High availability designed for continuous, 24/7 operation
Technology
◾ Refrigerant-based split cooling unit com- prised of an internal unit (evaporator coil) and an external unit with integral compres- sor (inverter-controlled)
◾ Optimum support of IT-compatible, “front-to-back” air routing
◾ Optimum adaptation of the compressor output to the current heat load of the IT rack with inverter control
◾ The internal and external unit are con- nected with refrigerant, data and supply lines
◾ Absorbed thermal energy is emitted via the external unit directly to the ambient air
◾ Control of the server air inlet temperature
◾ High level of fail-safeness thanks to availa- bility of single and redundant variant
◾ Ultimate security with optional alarm forwarding via CMC III
