TopTherm LCP Rack CW, 3311.260 WHD(mm) 300x2000x1200

TopTherm LCP RACK CW:



The design of the unit is optimised for use in data

centres. The integrated air/water heat exchanger

guarantees a cooling output of up to 60 kW, combined

with standard server enclosure dimensions, the lowest

possible weight and comprehensive possibilities for

monitoring.

The air/water heat exchanger is mounted on the side of

the rack.

LCP Rack CW offers enclosure-based cooling separate

from the room air and is thus also able to reduce the

noise level.

The unit is capable of providing cooling for either

one or two server racks.

The hot server air is drawn off to the rear of the

server rack. After cooling, it is expelled left and

right in front of the 482.6 mm (19") level over the

whole enclosure height and is thus made available to

the IT equipment once more.



The use of four integrated EC fan modules (cooling

output up to 40 kW) achieves maximum efficiency and

minimises the electrical energy consumption.

The unit is prepared for the incorporation of a

maximum of six EC fan modules (cooling output up to 60

kW). For this reason it is possible to retrofit two

additional fan modules up to full configuration and

achieving the optimum cooling output.

This safeguards the value of an investment where the

full cooling output is not yet required at the time of

initial operation.



The flow characteristics of the heat exchanger have

been optimised for the minimum possible pressure loss

on the air side. This in turn minimises the energy

consumption of the fans.

The high-performance heat exchanger guarantees maximum

cooling output even at high water inlet temperatures,

enabling the proportion of operation in combination

with indirect free cooling to be maximised and

operating costs reduced accordingly.



The air/water heat exchanger and server rack remain

separate from each other. This eliminates the risk of

water penetrating into the server rack and improves

the ease of installation and service.

Condensate and leakage management is integrated.

The water connection can be realised optionally to the

top or bottom by way of an accessory kit

(1 1/2# thread).

Fast commissioning of the unit thanks to fast and

simple air bleeding.



The standard integrated software/controller concept

provides for automatic control of the specified server

air intake temperature. The fan speed and cooling

water flow rate are both infinitely variable, for

precise matching to the power losses of the components

installed in the IT rack.

The optimum operating point is thus achieved with

minimum energy consumption and correspondingly reduced

operating costs.



An intelligent sensor network monitors the air and

water temperatures, as well as the water flow rate and

leakage management.

The incorporation of three temperature sensors for the

hot and cold air provides for redundancy. An

integrated fail-safe mode, furthermore, ensures

reliable cooling, even in case of failure of the

electronics.

The monitoring and alarm management for all physical

parameters is realised via SNMP and Ethernet. A BACnet

link is possible as an option.

New control algorithms permit energy-efficient

operation and take into account the demands of

facility management.



To enable the displaying of all physical parameters,

an optical colour touchscreen can be integrated into

the front of the unit.



The optimised layout provides for fast and simple

maintenance and service for all relevant components.

The fans can be exchanged at any time in a matter of

seconds, also during operation (hot swapping).

The temperature sensors in the water inlet/return are

integrated into thermowells and can similarly be

exchanged without interrupting operation.
