The Liebert® DSE DA250, 250 kW provides new levels of performance for colocation and cloud hosting facilities, with rapid deployment, low cost of ownership, high energy efficiency and low peak power. The system is ideal for raised or non-raised floor data centers. Its pumped refrigerant economizer uses no water and requires no outside air into the data center. A packaged condenser and refrigerant pump can be rooftop mounted, making it ideal for multi-story buildings.

Features

Uses a pumped refrigerant economizer and automated transitions to economization to cut energy usage
Units can be situated side by side to form a fan array to support loads of more than 250 watts per square foot, with servicing at the back
Slab coil design and top-to-front airflow make it ideal for slab floor data centers. Underfloor airflow is also available.

Benefits

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 area 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. Highly efficient in low load / part load conditionsLowers 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 centerSimplified 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 virtually maintenance free
No dampers to service or outside air filters to replace
