Better cooling systems

After your IT equipment, cooling systems are the most energy consuming system in your data centre. UPS losses are fractional compared with the energy consumed in cooling IT equipment. Today’s PUe metric has focused data centre designers to consider every aspect of energy consumption and loss. The ‘low hanging fruit’ has, and for some time, will continue to be reducing the cost of cooling a data centre however care must be taken to ensure temperature and humidity set points are achieved and heat density and airflow requirements are maintained.

Only a few years ago cooling technology and topology choice was very limited probably  involving  only a choice between different manufacturers of Direct Expansion, or CRAC and Chilled Water systems. The focus being on scalability with load growth favouring  the lower CAPEX option of  direct expansion at higher operating cost against the high CAPEX chilled water systems which provide lower OPEX costs long into the future.


Cooling systems are no longer discrete systems in the data centre. The advent of contained aisles (hot and / or cold) has extended the design of data centre cooling systems right into the IT white space. Substantial OPEX savings are available by using air containment systems at the rack level but careful consideration and design is necessary to ensure that the cooling system has sufficient cooling and air flow capacity to operate with controlled air flows.

At Powertechnix we consider that cooling is one vital area that needs to be carefully designed and developed as part of the data centre as a whole. Failure to integrate the cooling design will reflect in poor efficiency, poor air distribution, air starvation at the IT level and generally poor performance all adding to be increased OPEX for the life of the system.Our capability to design or deliver turn-key cooling systems provides you with professional, vendor agnostic advice from a data centre specialist.
