Turbomiser chillers halve cooling costs for data centre
The energy consumption of chiller plant at Colt’s data centre in Wapping, London, has been more than halved following its replacement with Turbomiser chillers installed by Cool-Therm. Six Turbomiser machines, each rated at 550 kW, deliver 3.3 MW of cooling. Not only has energy consumption been reduced by 55%, but there are also significant reductions in service and maintenance costs. The PUE (power usage effectiveness) for this data centre has also been reduced by 24%.
The contract was won following successful performance tests with Turbomiser at another Colt data centre.
Rob Young, head of the project for Cool-Therm, says, ‘Taking into account ambient fluctuations, annual savings are well over £100 000. This is with fan speeds limited to 60% of capacity due to site noise restrictions. If the fans were allowed to run faster using the new adaptive fan-speed control, savings would be even greater.’
Ken Strong, managing director of Cool-Therm said, ‘Turbomiser was not the lowest cost option on the table. However, the impressive energy savings that have now been proven in the previous Colt installation, plus savings in service costs, proved decisive in winning the contract.’
Turbomiser can achieve EERs of 10 and above without the need for additional free-cooling circuits using glycol, saving both on initial costs and ongoing pump energy.’
