NRG series perimeter-mounted air conditioning units are designed for high thermal density IT facilities requiring accurate hygrothermal parameter control and continuous operation. The use of inverter-driven compressors, capable of tracking the thermal load with extreme precision, of EC fans (standard), and of electronically controlled lamination valves (standard) also make it possible to achieve high performance with reduced energy consumption, improving the Data Centre's PUE. The strength of the new NRG range is the high cooling density (KW/m2), obtained thanks to the precise internal design, a frame of just 890 mm in depth, and the careful choice of components.
