Beneficios

Saves You Money High-efficiency pumped refrigerant economizer uses less than one-tenth the power of compressors Annual operational PUE under 1.2 Eliminates water usage, cost, and treatment Large condenser surface are minimizes operating and peak power to minimize generator backup or free up additional saleable IT power. No air leakage or volumetric displacement, eliminating the need for additional fan power or make-up air capacity Rapidly scalable for faster deployment and time to market Low operating costs for higher profitability. Higly efficient in low load / part load conditions Lower Your Risks Proven pumped refrigerant economization technology used in more than 4,000 to 8,500 installations worldwide Multiple fans, DX circuits and other key components for ride-through No air dampers or louvers to maintain Airflow up to 37,000 CFM supports lower delta-T in non-raised floor environments. Supports large, high-density data center suites requiring a low-complexity infrastructure. No outside air, contaminants or humidity allowed into the data center Simplified Thermal Management Advanced monitoring and control algorithms for multi-unit teamwork, automated transitions to economization and automated protection routines for unit lead/lag, coil freeze, and others Rear-access servicing means no need for mechanical service in the data center Refrigerant pump is vitually maintenance free No dampers to service or outside air filters to replace

Características

Pumped Refrigerant Economizer Advanced Thermal Controls Microchannel Condenser Independent Thermal System Design 50-265kW capacities Downflow configurations (50 - 265 kW) Upflow configurations (80 - 85 kW)    

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.
