- Article number:
- SK 3311.492
- Design
- LCU DX 6.5 kW
- Benefits
- Space-saving solution by installing the 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 device supports front-to-back air routing typical of IT applications, and regulates the server inlet temperature to the set value
- Material
- Sheet steel, spray-finished
- Colour
- Internal unit: RAL 7035
External unit: white - Supply includes
- Internal unit (evaporator coil)
External unit (inverter-controlled)
482.6 mm (19") mounting trim panel with display and control components
Condensate hose - Installation options in VX
- 482.6 mm (19") mounting angles, standard or dynamic, must be offset in the width by 50 mm off-centre
- The front distance between the 482.6 mm (19") mounting angles and the front edge of the VX frame must be at least 100 mm
- Two punched sections with mounting flanges are required for attachment on the inner mounting level
- Air baffle plates are required to separate the hot/cold zones within an enclosure
- A base/plinth is required to route the cable downwards
- Note

- SK LCU DX split cooling unit 6.5 kW, refrigerant-based cooling of IT racks and Micro Data Centers, 1 x external unit with inverter-controlled compressor, 1 x internal unit, single version
3311.492 LCU DX 6.5 kW
LCU DX, 6.5 kW split cooling unit consisting of an internal unit
(evaporator) and an external unit (inverter controlled cooling unit).
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, 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, a microprocessor controller is placed 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 unit.
The operating unit is 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 that belongs to the device is placed near the front
of the server.
The external unit with the inverter-controlled compressor permits
stepless power adjustment, even in partial-load operation (3-6,5 kW).
The connection between the internal unit and the external unit is made
by means of copper piping, a data line and the power supply.
The internal device is supplied with voltage by the external device.
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.
