the latest versions of rittal’s liquid cooling package (lcp) units have added fans to move air more efficiently and with less effort. and, using six fans has proven to consume less energy than the traditional use of three or four. more fans, each running at slower speeds, draw less energy while moving an equal or greater volume of cool air. while the standard 30kw lcp still comes equipped with three ec fans, this latest adaptation also makes the cooling solution more scalable, improves redundancy and reduces overall noise levels. in addition, all the fans have been moved to the front of the units away from the maximum heat generated by computer components. this design feature not only improves heat dissipation, it will extend the life of the fans.

rittal’s lcp units can be configured to cool 10-20-30-40-50-60kw, making them far more responsive to the demands of today’s data centers. the next generation lcp units are truly scalable – going from 10 to 20 and 20 to 30kw just by adding fans to the system; or from 40 to 50 or 60kw by adding fans and a larger heat exchanger.

under normal conditions, three ec fans require approximately 1,168 watts of power and operate at 67 dba. adding a fourth fan reduces the power consumption to 893 watts and reduces the accompanying noise to 64 dba. using five fans reduces power consumption to 717 watts while further reducing overall noise levels to 62 dba. adding a sixth fan reduces energy consumption to 669 watts and further reduces noise levels to just 60 dba. the addition of these high efficiency fans means that each fan can run less and run at a slower speed reducing the energy it requires and the level of sound it produces.

at least as important in the overall scope of data center design, this increased capacity is available within the same footprint as existing models — 60kw cooling can be realized from a unit that’s still just 12 inches wide. that’s as much as double the standard cooling from the same floor space — or by reducing the number of units, floor space can be freed up for additional hardware. this unique design and ability to use the same floor space for more efficient operation is exclusive to rittal’s lcp.

the rittal advantage:

• high performance cooling — up to 60kw using 59^o water. operation above dew point increases energy efficiency and eliminates condensation

• high-efficiency monitoring — server-friendly temperature monitoring plus communication via snmp over ethernet

• high-tech fans — ec fans for cold area feature both economy and facility modes to boost efficiency. cooling capacity varies with number of fans. box-type, plug-in fans can provide n+1 redundancy.

• installation-friendly — mechanical connections available from top or bottom; low weight for low load on raised floor

• operational efficiencies — equal temperature distribution throughout the rack; high energy efficient ratio (eer) at the chilling
