£50,000 per month saved for mission critical data centre
T
he challenge for today’s data centres is how to reduce operating costs and satisfy environmental concerns. But when it comes to the provision of fi nancial services, avoiding downtime is paramount as the Financial Conduct Authority (FCA) takes a tough stance when it comes to IT failures.
Building on its successes in delivering cooling solutions for the fi nancial services sector, Aermec has recently completed a chiller replacement using robust and proven technologies, to deliver improved cooling reliabilities, energy savings and reduced emissions for the global data centre of one of the UK’s leading multi-national fi nancial powerhouses.
Background
Data centres generate signifi cant amounts of heat. Cooling is a critical part of the infrastructure and when it comes to replacing equipment in a live mission critical site, there are a number of regulatory requirements and logistical challenges

to overcome. Customer expectations also have to be managed.
When the data centre for one of the of the country’s top banking and fi nancial companies decided to replace all its chillers, their key requirements included resilience, energy effi ciencies, reduced emissions and lower Power Usage Eff ectiveness (PUE).
In line with its own environmental and sustainability policies, the company sought minimal environmental impact. Free cooling chillers off ered a smarter approach to cooling as making use of the outside air reduces the use of mechanical cooling throughout the year and this strategy is deployed by many data centres. Behind the security barriers and virtually windowless building of a 30,000sq metre site on an unobtrusive industrial estate in west London, a phenomenal one billion fi nancial transactions are carried out every second. Re-designing the cooling and replacing the chillers required careful planning.
“This is our global hub. Cooling is critical to our infrastructure. Any disruption with the cooling could impact the UK’s fi nancial services but the ramifi cations could potentially be felt globally,” said the company’s facilities manager. Following extensive evaluation and analysis, and working in close collaboration with RED Engineering Design, the MEP design consultancy, m&e contractors Gratte Brothers and Aermec distributor AEUK, free cooling chillers designed and manufactured by Aermec were selected. As a global business, the fi nancial corporation’s ethos is to minimise its environmental impact and reduces carbon emissions across all its business platforms. By investing in the latest technologies, the company expected to satisfy its stringent criteria and boost its green credentials. But it also wanted to be a good neighbour. Noise breakout from the site was minimised by designing extra low noise chillers which satisfi ed the requirement of the customer and the local council.
