Data centre CRAC is a common abbreviation for Computer Room Air Conditioning.

Used to control and maintain an optimal temperature, distribution and air flow within data centres and network areas, they can mean the difference in your computers breaking down or running to peak standard.Computer Room Air Conditioning Units or data centre CRAC units are becoming more and more commonly used to replace the standard air conditioning within computer rooms of the past.

Many business operators don’t realise that without utilising a data centre CRAC, mainframes and racks of servers can get as hot as a 2-metre tower of powered toaster ovens. Controlling the temperature of computer infrastructure is important in ensuring its smooth running.

There are a number of options around how data centre CRAC units can be set up or situated. One option is having air that has been through a cooling process dispensed through an elevated floor, as shown in the diagram on the right. Cool air flows through the racks, heating up by the time it is purged through the back of the racks. Hot aisle/cold aisle raised floor positioning data centre CRAC units are one of the most popularly used.

Effective temperature control impacts on both the functionality and reliability of a computer room ensuring the network area is set to an optimal temperature for peak performance.

In rooms exposed to high-level temperatures due to the capacity of computer hardware in data centres and network areas, data centre CRAC units regulate thermal conditions ensuring prime temperature for data centres to operate within. They protect against network area and data centre breakdowns and permanent damage to hardware due to overheating that can often be experienced. Data centre CRAC units work to ensure precise humidity levels and consistency of temperatures ideal for high loading areas such as data centres, server rooms and network areas.
