Liebert - Cooling and HVAC Solutions

Liebert XD^TM System

Liebert energy-efficient and flexible high heat density cooling solutions are available with Open or Closed architecture and Pumped Refrigerant-based or Water-based technology.

Liebert XD cooling modules are available in configurations to suit individual application requirements:

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-the-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.

Flexibility:

• Cools more than 30 kW per rack.
• Requires little or no floor space.
• Complements Liebert precision cooling units.
• Allows adaptive and scalable expansion without interruption of cooling operations, with optional pre-charged flexible piping with threaded quick connect fitting.
• Provides models to suit data center needs, mounting on, above or between the racks.
• Provides an excellent solution for spot and zone cooling of high heat density equipment.
• Offers 60 Hz and 50 Hz models.
  

Higher Availability:

• Uses pumped refrigerant, which is ideal for use around electronic equipment.
• Ensures continuous operation of critical IT systems under extreme heat conditions.
• Includes coil, controls, fans and piping for a complete, packaged unit.

Lowest Total Cost Of Ownership:

• Operates with high energy efficiency.
• Offers superior cooling cost per high heat density rack.

Ideally Suited For:
Supplemental sensible cooling for high heat density racks or zones

Ceiling and Wallmount

Liebert solutions provide year-round precision cooling and humidity control of small areas such as computer, control and equipment rooms where people and sensitive electronics share the same space. These space-saving systems are available in configurations and sizes to meet the needs of electronic equipment in tight spaces.

Designed for precision cooling, humidity control and air filtration of small areas, such as computer, control and equipment rooms, Liebert Mini-Mate2 installs above a dropped ceiling. The system is easy to install and service, and requires only front access for maintenance.

 Liebert Mini-Mate2 is available in nominal cooling capacities from 3.5 to 28 kW (1 to 8 tons). Air, water, glycol and chilled water models are available in 50 and 60 Hz. All chilled water systems are self-contained units; air, water and glycol cooled models are available in split system configurations.

Flexibility:

• Requires no floor space, with the evaporator and indoor condensing units mounted above the dropped ceiling.
• Requires only simple thermostat-type wiring to split system controls and condensing units.
• Services from the unit front for easy component access.

Higher Availability:

• Features reliable refrigeration components such as high efficiency rotary or scroll compressors, and copper-tube aluminum fin coils.
• Runs efficiently at partial load conditions with hot gas bypass feature, eliminating compressor wear from start-stop cycles.

Lowest Total Cost Of Ownership:

• Takes advantage of colder outdoor temperatures and bypass compressor operation with energy-saving Free-cooling option.

Ideally Suited For:

• Network closets
• VoIP
• IDF
• Telecommunications equipment
• Data processing
• Control rooms
• Desktop publishing
• Network facilities
• Laboratories
• Other critical electronic systems

Heat Rejection

Liebert system-matched condensers, drycoolers and condensing units ensure continuous, proper operation of your cooling systems. The units are available in a variety of configurations, including high energy efficiency models and low noise models.

Liebert system-matched condensers, drycoolers and condensing units ensure continuous, proper operation of your cooling systems. The units are available in a variety of configurations, including high energy efficiency models and low noise models.

Liebert Outdoor Condensers are available in a wide range of capacities from 17.5 to 210 kW (5 to 60 tons), 60 Hz or 50 Hz. The units are quickly and easily installed, because all internal wiring is completed at the factory with only two electrical connections to be made at the job site.  

Liebert Air-Cooled Condensers are low-profile, direct-drive propeller fan type air-cooled condensers, using either one or two separate circuits. Liebert Quiet-Line outdoor condensers are designed to meet the strictest municipal noise codes with sound levels of less than 57 dBA.

Liebert TCDV Condensers utilize a Variable Frequency Drive to control fan speed, for energy savings compared to standard condensers. Designed for use with dual refrigeration circuit cooling systems, including those with digital scroll compressors, they enable operation in outdoor temperatures as low as -20°F (-28.9°C).

Flexibility:

• Operates at outdoor temperatures as low as -30°F (-34.4°C) with available Liebert Lee-Temp system.
• Meets the strictest municipal noise codes, with sound levels of less than 57 dBA (Quiet-Line model).

Higher Availability:

• Offers durable construction with a corrosion-resistant aluminum cabinet, copper-tube aluminum-fin coil, and galvanized steel internal frame.
• Provides air flow by efficient direct drive fan/motor combination.

Lowest Total Cost Of Ownership:

• Delivers to the site fully wired, piped and tested.
• Allows faster and efficient plan approval and building inspection with CSA agency approval.

Ideally Suited For:

• Data centers
• Telecommunications facilities
