The Liebert dual-circuit chilled-water cooling unit from Emerson Network Power has two independent circuits that enable maximum availability of air conditioning for data centres and technological sites, which makes for flexibility and energy savings
With two independent circuits within one unit, the Liebert HPM Dual CW can perform a cooling action during the working day through its primary circuit.
At night, when air-conditioning needs are less, it can use the secondary circuit with a smaller chiller. Electronically commutated fans can be used in tandem.
