LCP Plus EC WHD (mm) 300x2000x1200



LCP Plus EC, technical description:

The air/water heat exchanger designed for the climate

control of server racks in data centres offers a

controlled, tailor-made, energy-optimised cooling

capacity of up to 30 kW with a minimum weight and a

comprehensive possibility of monitoring.



The air/water heat exchanger is mounted at the side

of the rack.

This ensures a full separation of IT and Facility

Management - even in the event of maintenance access

only to the LCP Plus EC.



The LCP Plus EC draws in the hot air at the sides of

the server enclosure rear, cools it using

high-performance compact impeller heat exchangers,

and blasts the cooled air back into the front part of

the server enclosure at the sides.

Thus an even, horizontal climate control over all

height units in the server rack is achieved.

Cooling of the installed 482.6 mm equipment is

ensured even when the enclosure doors are opened

(e.g. for maintenance purposes).

Optionally one or two server racks may be cooled with

one LCP Plus EC.



Maximum efficiency is achieved and electrical power

consumption is minimised due to the use of EC fans.

The large-scale high performance heat exchanger of

the LCP Plus EC makes high inlet temperatures (up to

21°C) and low pressure loss on the water and air side

possible.

Thus a remarkable extension of free cooling and

reduction of electrical

power consumption of the pump system is achieved.



Air/water heat exchanger and server rack are

spatially separated.

Condensate and leakage management is integrated.

The water connection may be routed via 1" external

thread towards the bottom or the rear.

The fans may be exchanged without tools.

Network integration for monitoring/setting all

technical parameters is possible.



Extremely robust thanks to its simple, optimised

construction.

Strict spatial separation of water-carrying and

electrical components. All electrical components are

additionally protected against splashing water.



TÜV GS certified, complies with condensate test to

DIN 3168.

UR approval as standard.



Control

Optimum adaptability (0-100%) thanks to dynamic,

continuous control of the

cold water flow.

Control of constant server inlet air temperature by

continuous adjustment of the

volumetric air flow based on the temperature

difference (inlet air - outlet air) for

the best possible and highly efficient power supply

to the server systems.

The unit is designed according to the "fail safe"

principle. In the very unlikely event of

failure, the unit automatically switches over to

maximum cooling output.



Standard redundant design of the air temperature

sensors required for control.



Service:

The six fans may be individually exchanged with the

system operational and are self-contacting.

Control is being continued in case of a fan failure /

exchange. There are

no settings necessary before or after the fan

replacement.

The replacement of individual fans is possible within

30 seconds.

The unit has an automatic vent valve, thus ensuring

the fast availability of the unit during

implementation.





Monitoring:

Extended functionality of the monitoring and control

technology/software via SNMP.

Basic CMC with Ethernet interface as standard.

Graphic user interface thanks to integral webserver.

Constant display and monitoring of all relevant

operating parameters such as inlet/outlet air

temperatures, flow, inlet/return temperatures, fan

speed, dissipated heat loss etc.

Standard touchscreen display for monitoring and

operating work on the unit.
