Designed to minimise energy
use, the CDU rejects 305kW of heat using only 4kW of power in less than a square metre of floor space. End customers include many world-class universities as well as leading scientific and financial institutions running high-density applications. Eaton-Williams’ data centre
cooling portfolio offers energy efficiencies, lower emissions, reduced carbon footprints and built-in redundancy, all of which help to maximise ROIs. Eaton- Williams has also pioneered free cooling technologies, including the world’s first zero-carbon data centre in Iceland for Verne Global.

LiquidCool Solutions (LCS) is a technology development firm with patents surrounding cooling electronics by total immersion in a dielectric fluid. LCS technology can be used to cool electronics of any shape and size. For rack-mounted servers the dielectric fluid is
Motivair manufactures ultra- high efficiency Chilled Doors for HPC applications. Tese active rear doors remove up to 45kW from a 42u x 600mm rack, using variable speed fans, water control valve and PLC controls with remote communication. Tis performance is achieved using 65F water and maintaining 75F (intake & discharge air) room temperature. Using 65F chilled water
eliminates any possibility of condensation or the need for condensate pumps. Te total Chilled Door fan power requirement of 840 watts at 45kW capacity is entirely offset by the reduction in server fan power, independently measured at 1kW by a major server manufacturer in their test lab. Terefore there is a small net power reduction for an HPC rack fitted with a Motivair

pumped from a central station through a manifold mounted on the rack into sealed IT devices, flooding each chassis and slowly flowing over and around the circuit boards and internal components via directed flow. Once the coolant exits the enclosure it is circulated outside the data centre, where the heat is captured for commercial reuse or rejected to the atmosphere by a commercially available fluid cooler. LCS licenses its IP to OEMs
looking for a cooling solution that saves energy, saves space, enhances reliability, operates silently, and can be surprisingly easy to maintain in the field. Te fact that LCS cooling technology can dissipate 100 kilowatts per rack and costs less, are just added benefits.

Saves up to 90% power over traditional data center cooling systems
45 kW and above cooling capacity F chilled water
also reduces the power cost of a dedicated chiller by 30 per cent resulting in an extremely efficient system. Any building central chilled water supply can be tempered from 45o
F to 65o F
by utilizing a Motivair cooling distribution unit (CDU).
