The Liebert® DSE Freecooling Solution provides high efficiency, water-free economization, maximum reliability, low maintenance and rapid scalability – all in highly flexible split-system configurations. Its pumped refrigerant economizer captures the most economization hours across the widest range of temperatures, compared to other similar systems. The Liebert® DSE packaged solution uses proven pumped refrigerant economizer technology that is deployed in more than 6,000 to 8,500 sites around the world. With a highly flexible design, the solution is available in configurations from 50kW to 265kW. 60kW, 400kW and 500kW capacities. Highly Flexible. The system provides split-system refrigerant economization with more than two dozens configurations for airflow, form factor and capacity. It can be deployed in perimeter, gallery and full-face discharge applications for raised floor and non-raised floor data centers. No Outside Air. The system’s pumped refrigerant technology separates outside air from data center air to eliminate cross-contamination or humidity transfer. Finely Tuned Controls. The system’s industry-leading Liebert® iCOM™ controls capture every available economization hour, with smooth, automated transitions. Advanced protection routines keep the system operating safely within thresholds. Automatic, multi-unit teamwork modes harmonize thermal management across the data center. Optimization routines reduce energy usage by up to 50% over previous versions. Onboard protocols make integration with building management systems easy. Easy Servicing. The Liebert® DSE has fewer moving parts than other economizer systems, reducing the likelihood of component downtime and maintenance. All components can be serviced from the back of the unit, allowing for more flexible installation options.

Air-cooled free-cooling system with water-free economization, a rapidly deployable configuration and advanced Liebert® iCOM™ thermal controls to optimize each unit and harmonize the operation of multiple units for temperature and airflow. Highly scalable and modular design accommodates changing IT loads and is ideal for upgrading outdated or inefficient cooling systems.
