The Liebert® DSE™ 400kW Packaged Solution is an ideal solution for large data center rooftop applications requiring maximum reliability, high efficiency, low peak power, no water usage, low maintenance and rapid scalability. The system is available as a single package from the factory in 400+ kW capacity increments for both rooftop and outdoor perimeter applications. It offers maximum annualized efficiency through the use of a pumped refrigerant economizer deployed in more than 4,500 installations worldwide.
A more consistent and reliable data center environment is supported through physical separation of heat rejection and data center air to avoid cross-contamination or transfer of humidity. The system has minimal air leakage, with less than 0.5% leakage at normal operating pressures and no volumetric displacement commonly associated with heat wheel applications. Low peak power enables data center managers to reduce generator sizing or to have more available IT power for sale. The system’s advanced Liebert iCOM controls provide automatic protection routines, multi-unit teamwork and greater annual efficiency.
