PRODUCT DESCRIPTION
The Liebert® EconoPhase Pumped Refrigerant Economizer has changed the face of data center cooling by providing high efficiency without using water. The first pumped refrigerant economizer for data centers, this innovative technology is installed in more than 6000 locations worldwide. It offers significant advantages over passive thermosiphon systems. The economizer is a critical part of the Liebert DSE system, working with the indoor evaporator and Liebert MC or MCV Outdoor Condensers to significantly improve data center efficiency —without bringing in outside air and without using water.
- Active refrigerant economizer provides more hours of annual free cooling than passive thermosyphon systems
- Pumps use less than one-tenth the energy as CRAC compressors
- Refrigerant carries 2 times twice as much heat as water and 40 times as much heat as air
- Instant changeover to economizer mode, even for short periods
- No outside air contamination, and no dampers or louvers to maintain
- Automatic failure diagnostics; pump unit serviceable without loss of cooling
- Virtually maintenance-free, with no moving parts except the sealed pumps
- Can be installed as a unit or as part of a bundle with the Liebert MC or MCV
- Allows for greater line lengths than passive thermosiphon systems (up to 300 ft)
