Product Overview
The Liebert DSE is a packaged free-cooling solution built around pumped refrigerant economizer technology: refrigerant is circulated by a pump rather than a compressor whenever outdoor conditions allow, cutting mechanical cooling energy dramatically. Vertiv specifies a partial PUE (pPUE) below 1.095 for the system.
The China packaged version covers single-unit capacities from 220 kW to 300 kW and scales to 400 kW, providing cooling for containerized and modular data centers. The family also includes 80-150 kW and 250 kW DX cooling and refrigerant economizer variants documented on Vertiv’s international sites.
Vertiv.cn publishes official product imagery including front, side and LCD detail views, and the DSE targets regions with favorable climates where free cooling hours significantly reduce annual cooling energy in modular and conventional data centers.
