- Pumped refrigerant economizer uses less than one-tenth the power of compressors
- Highly efficient in low load/part load conditions
- Low max kW for more available IT power
- Rear-access servicing
- No need to enter the data center
- Refrigerant pump is virtually maintenance free
- No dampers to service or outside air filters to replace
- High-density design supports loads of more than 250 watts per square foot
- Units can be situated side by side to form a “fan array”
- Underfloor or front air discharge
- Advanced Liebert iCOM™ monitoring and control algorithms for multi-unit teamwork, automated transitions to economization and automated protection routines
Cooling equipment accounts for as much as 40% of data center operating costs.¹ A chilled water cooling system for a 1MW data center uses around 4 million gallons of water annually.²
Colocation, cloud hosting and other large data centers need cooling solutions with low total cost of ownership-solutions that save energy, conserve water, reduce risks and simplify thermal management.
The Liebert® DSE™ Freecooling System is the world's most efficient and reliable water-free cooling system for data centers. The Liebert DSE 250kW split-system is highly efficient, uses no water, is rapidly deployable and has an attractive total cost of ownership. It uses the proven pumped refrigerant economization technology from Vertiv deployed in more than 4,000 installations worldwide.
