Precision Emerson XDFN conditioners
Decisions for the modern Data-processing Centres (DPC). The technology of cooling Liebert XDFN was specially developed for already existing and new Centers of processing of information - it is urged to obespechivait the effective, economic and fast solution of problems of cooling is an optimal solution for cases when interruptions in work of the equipment are inadmissible, or expansion of object is expected.
Cooling with the closed cycle for racks with a high thermal emission - XDFN
– technology of the closed cooling in racks. At the same time cooling directly of servers is carried out, but not the working room - the safe decision protecting from the problems connected with an equipment overheat is provided the possibility of full reservation, protection on power supply, the fire alarm system and emergency ventilation is provided.
Thanks to an extensive experience of creation of systems precision klimatkontrolya and systems of uninterrupted power supply the Emerson Network Power company developed the unique decision for servers providing both internal cooling, and the built-in reserve uninterrupted power supply.
Racks of Liebert XDFN can be established not only in specialized rooms for server and the centers of processing and storage of information, in principle they can be established in any room, even for this purpose specially not intended.
The rack can be completely filled with the servers calculated on standard 42 1U racks.
The modular design of racks of Liebert XDFN gives the chance of reservation, allows to replace easily failed modules, provides flexibility and economy of working space in the center
Liebert XDFN modules can be combined for collaboration, it is very important when in information centers especially high power of cooling is required - at the same time the additional module can provide full reservation of cooling in XDFN racks.
All blocks are connected in a local network, and, in case of failure of one of the working blocks, the reserve block can be switched immediately on in work - the system of microprocessor management provides also periodic alternation of the main and reserve modules.
Also the system of emergency ventilation is provided in each rack of Liebert XDFN. Fans receive power supply from the UPS providing protection against sharp temperature increase in a rack at shutdown of network power supply.
Modules with automatic control of power of cooling from 2 kW to 24 kW, or in other range of work are usually used, depending on the order of the user - also versions with the cooled water are possible
Remote control and opportunity "-is hotter" - replacements of the failed elements allow to avoid interruptions in work of system.
