Liebert XD Refrigerant-based Cooling Modules |
| |
|
| Liebert XD refrigerant-based cooling modules work as a system to support the hot aisle/cold aisle approach to cooling high heat density data centers. The modules provide focused rack cooling, enhancing a room precision cooling unit, such as a Liebert DS system. Pumped refrigerant is ideal for use around electronic equipment, operating at low pressure in the piping circuit, and becoming a gas at room conditions. |
|
| Liebert XDO overhead cooling module mounts directly above the cold aisle, requiring no floorspace. It draws in hot air from the hot aisle, then discharges cool air into the cold aisle where the equipment air inlets are located. |
|
| Liebert XDV rack cooling module mounts vertically on or above the IT rack enclosure, requiring no floorspace. It draws hot air from inside the cabinet or from the hot aisle. It then cools the air and discharges it down to the cold aisle. |
|
| Liebert XDH in-row cooling module is placed directly in line with the rack enclosures, and requires very little floorspace. Air from the hot aisle is drawn in through the rear of the unit, cooled, and then discharged horizontally through the front of the unit into the cold aisle. |
|
| Liebert XD CoolFrame cooling module is designed to install on the back of the Egenera Bladeframe EX system, providing cooling without increasing the rack footprint. |
