What is a Liebert CRAC?

What is a Liebert CRAC?

A Liebert Thermal Management Unit, also known as a Liebert Computer Room Air Conditioning (CRAC) unit, is a highly efficient and scalable cooling system. It addresses the unique vulnerabilities of your company’s IT equipment that is always on and at a higher risk of overheating-related failure.

Who bought Liebert?

Emerson acquires Liebert Corporation, a pioneer in thermal management and power protection for information technology systems.

How does a CRAC unit work?

CRAC units work just like the air conditioning units in your home. They have a direct expansion system and compressors built right into the unit. They provide cooling by blowing air over a cooling coil filled with refrigerant. The refrigerant maintains its cool state by a compressor within the unit.

What is data center cooling?

Through effective containment, data centers can reduce the risk of hot and cold air mixing. Free cooling can also help to improve data center energy efficiency. There are a number of forms of free cooling, including thermal reservoirs, low-temperature ambient air and evaporating water.

How much are CRAC units?

This complex system requires over a dozen 10- and 20-ton CRAC units, all of which cost roughly $1000 per ton in addition to the installation, maintenance, and energy costs.

Is Vertiv the same as Liebert?

Liebert Corporation, a business of Vertiv, is a global manufacturer of power, precision cooling and infrastructure management systems for mainframe computer, server racks, and critical process systems.

What is inside a CRAC unit?

A computer room air conditioning (CRAC) unit is a device that monitors and maintains the temperature, air distribution and humidity in a network room or data center. The warm exit air forms hot aisles behind the racks, and the hot air returns to the CRAC intakes, which are positioned above the floor.

How much does a CRAC unit cost?

How do data centers keep cool?

A data center cooling system commonly used in mid-to-large-sized data centers that uses chilled water to cool air being brought in by air handlers (CRAHs). Water is supplied by a chiller plant located somewhere in the facility.
