Netwise Hosting, one of London’s leading data centres, has just completed its second EcoCooling installation within its estate. Netwise began its journey in South London, with a much smaller facility where standard cooling systems were not an option. EcoCooling’s smaller external modular units (ECP60-02 wet box units) alongside efficient EC fans provided the ideal alternative. These were chosen for the initial installation as they were cheaper to install and Netwise could perform a majority of the installation works themselves. The control systems also allow for exact supervision of temperatures and built-in safety measures.
In June 2015 Netwise moved to Central London and opened a bigger facility. Following on from the success of the first installation, EcoCooling was chosen to be an integral part of this next development. Three of the wet boxes were able to be moved across to the new site, with only a few minor modifications being made at the EcoCooling workshop.
In London, power is already a struggle, so choosing a more environmentally friendly cooling system is also a cost-cutting step, and has a knock-on effect for customers. EcoCooling direct evaporative cooling units alongside their energy optimising control systems can provide 100kW of cooling. Evaporative cooling is a very energy efficient way of cooling, and the new project allowed Netwise to push the design of the system further, stacking multiple units together resulting in an operating capacity PUE of just 1.12.
From an end user perspective, the EcoCooling system is easy to use, as each custom cooling stack has its own controller, and the entire cooling system can be managed via a single control unit, or remotely over the internet. Using an upscaled version of the South London system, Netwise was able to increase the resilience and cooling output, while keeping the on-going costs down. In this way there can be a 90-95% saving with EcoCooling systems versus the same output achieved if standard refrigerant-based products were used.
The long-term plan for Netwise is to build a host of private, bespoke data centres around the UK (and maybe Europe), which will be highly interconnected offering a truly global hosting platform, and EcoCooling systems are anticipated to be an integral feature throughout this vision.
