Specifications

Benefits

Space-saving solution by installing the redundant internal unit in the VX IT server enclosure or the Micro Data Center, Maximum energy efficiency due to EC fan technology and IT-based control, Control of the server inlet temperature, The inverter-controlled compressor matches the cooling output to the current level of heat loss in the enclosure, Absorbed thermal energy is emitted directly into the ambient air at the location of the (inverter controlled) external unit , without heating up the installation room

Function principle

["Within the internal unit, the redundant versions each have two cooling circuits and two controllers, plus two inverter-controlled external units. The fault and operating hours switchover mechanism ensures regular switching between the external units and a switchover in the event of a fault or a failure.","The device supports "front to back" air routing typical of IT applications, and regulates the server inlet temperature to the set value"]

Installation options in VX

["19" profile rails, standard or dynamic, must be off-centered by 50 mm in regards to width","The distance between the front of the 19" profile rails and the front edge of the VX frame must be at least 100 mm","Two system chassis for the inner mounting level are required to fasten the internal unit","Air baffle plates are required to separate the hot/cold zones within an enclosure","A base/plinth is needed to route cables downwards"]

Note

If the cooling output falls below its minimum value, fluctuations in the air intake temperature may result, The electrical connection is made to the external unit, the internal unit is supplied by the external unit, A separate power supply is required for each external unit
