Article number: SK 3313.410

Rack-based cooling on one to two IT racks. Continuous cooling output adjustment due to the use of an output-controlled compressor in the LCP Rack DX (evaporator) An external condenser is required to operate the unit.

Article number:
SK 3313.410
Design
DX
Benefits
Maximum energy efficiency due to EC fan technology and IT-based control
Minimal pressure loss at the air end, which in turn minimises the power consumption of the fans
Control of the server inlet temperature
Thanks to the speed-regulated compressor, the cooling output is ideally adapted to actual requirements
With redundant temperature sensor integrated at the air end as standard
Specific maintenance of the LCP DX due to separation of cooling and server racks
Applications
Ideal for IT cooling of small and medium-sized locations
One or two racks can be cooled separately
Function principle
The LCP draws in the air at the sides at the rear of the server enclosures, cools it using high-performance compact impellers, and blows the cooled air back into the front part of the server enclosure at the sides
Absorbed thermal energy is emitted to the ambient air at the external condenser location, without heating up the installation room

LCP Rack DX, 3313.410 WHD (mm) 300x2000x1000

IT-optimised design, providing ideal support for "front-to-back" air
routing for the 482.6 mm (19") installations.

As a direct condenser, the integrated air/refrigerant heat exchanger
guarantees a cooling output of up to 12 kW with standard server
enclosure dimensions, the lowest possible weight, and comprehensive
possibilities for monitoring.
The LCP Rack DX is mounted on the side of the rack, with which it then
forms a closed system.
The warm server air is drawn in directly from the rear of the rack and
the cooled air is blown back in front of the 19" equipment level from
the side, over the whole height of the enclosure.
The LCP Rack DX is closed up to the server rack at the front and rear
and there forms a flush joint with the rack.
The LCP Rack DX can be used to cool either one or two server racks.

In its maximum configuration, the unit is equipped with four EC fans,
for maximum efficiency and minimum power consumption.
The flow characteristics of the heat exchanger are optimised for the
lowest possible pressure losses on the air side. This minimises the
energy consumption of the fans.

An integrated inverter with corresponding controller serves to regulate
the speed of the installed compressor.
This permits stepless adaptation of the output, also in partial-load
operation, and by reducing energy consumption also achieves a reduction
in operating costs.

Alongside the compressor, the cooling circuit of the LCP Rack DX
comprises a collecting tank, liquid separator, electronic expansion
valve, optimised heat exchanger, high and low-pressure sensors, Schrader
valves, filter dryer, non-return valve, high-pressure switch and
shut-off devices.
The refrigerant connections and the electrical power connection to the
unit can be realised from above or below.
The system comprising LCP Rack DX and external condenser must be filled
with refrigerant R410A after installation at the site.

The LCP Rack DX and the server rack remain separate from each other.
This simplifies assembly and service work and excludes the need for
unwanted access to the server rack for maintenance purposes.
Maintenance and service for all relevant components can be realised
quickly and simply thanks to the optimised layout. The fans can be
exchanged quickly and at any time, even while the system is operational
(hot swapping).
The fans are installed in the cold air section, which increases their
service life.

Condensate management is integrated into the unit. Any condensate is
collected in a collecting tray in the base and from there discharged to
the outside via a hose.

Thanks to the integrated controller, the LCP Rack DX operates fully
autonomously. The setpoint is the server intake air temperature, which
is automatically held constant at the set value.
Three sensors are present in each case for detection of the cold and
warm air temperatures, providing for the appropriate redundancy.

Monitoring and alarm management for all physical parameters is realised
via SNMP and Ethernet.
The SNMP card is integrated as standard in the electrical box, already
connected to the main board.

A display with operating keys is integrated on the front of the unit to
display and set the physical parameters.

The external condenser SK 3311.360 is needed to operate the LCP Rack DX.
Installation and commissioning on site, laying of the refrigerant pipes,
and evacuation and filling of the system with refrigerant are not
included in the scope of supply and must be realised by correspondingly
qualified persons.
