    + Product description

    Design: LCU DX 6.5 kW redundant
    Benefits: Space-saving solution by installing the redundantly designed 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 adapts the cooling output to the current heat loss inside the enclosure
    Absorbed thermal energy is emitted directly to the ambient air at the (inverter-controlled) external unit's location, without heating up the installation room
    Applications: Cooling unit for VX IT server racks and for Micro Data Centers
    Function principle: The redundant variants have two cooling circuits and controllers inside the internal unit, plus two inverter-regulated external units. The fault and operating hours changeover allows regular switching between the two external units, and ensures automatic changeover in the event of a malfunction or failure.
    The device supports front-to-back air routing typical of IT applications, and regulates the server inlet temperature to the set value

    3311.493 LCU DX 6.5 kW, redundant

    LCU DX split cooling unit, 6.5 kW, redundant, consisting of an internal
    unit (evaporator) and two external units (inverter-controlled cooling
    units).

    The internal unit is designed so that it can be installed in a 800 mm
    wide VX IT server enclosure or in a Micro Data Centre.
    It is constructed in IT-optimised design, so that the "front to back"
    air routing of the 19" components is ideally supported.
    The preferred area of application is in small to medium-sized locations,
    in which the server racks are cooled directly - without cooling the
    entire room.
    The LCU DX internal unit is mounted laterally in the server enclosure or
    in the Micro Data Centre and it forms a closed system with the latter.
    The internal unit of the LCU DX extracts the warm server exhaust air
    directly from the rear part of the enclosure and blows the cooled air
    laterally in front of the 19" level.
    The enclosure of the internal unit consists of powder coated sheet steel
    in RAL 7035, in which a direct evaporator with two cooling circuits,
    four EC radial fans, condensate tray and condensate discharge are
    integrated.
    The condensation discharge has to be provided on-site.
    The devices are constructed in such a way that assembly can be carried
    out in the IT server rack on the left or right.
    In addition, two microprocessor controllers and a fault and operating
    hours switch are located in the internal unit.
    The reference variable that controls the device is the server air inlet
    temperature.
    This can be set at between 17 and 30°C on the remote operating units.
    The operating units are installed in a 19" trim panel (3 U). This is
    mounted on the rear 19" level of the VX IT rack or of the Micro Data
    Centre.
    The external sensor devices (2 items) belonging to the units are placed
    near the front of the server.
    The two external units with inverter-controlled compressors permit
    stepless power adjustment, even in partial-load operation (3-6,5 kW).
    In the normal state, one external unit is in operation. The fault and
    operating hours switch allows a regular exchange between the two
    external units, as well as a change-over in the event of a disruption or
    a failure.

    The connection between the internal unit and the two external units is
    made by means of copper piping (2 cooling circuits), as well as two data
    lines and two power supplies.
    The internal device is supplied with voltage by the external devices.
    R410a is used as a refrigerant.
    The on-site installation and commissioning, the laying of refrigerant
    lines, and the evacuation and filling of the system with refrigerant are
    not included in the range of goods and services supplied. This work must
    be performed by qualified personnel.
