EcoCooling joins the Node Pole Alliance

EcoCooling, the leaders in direct-air evaporative cooling, has joined the Node Pole Alliance, an active international network of over 80 world leading knowledge partners coming together to build the data centres of the future.
The Node Pole region encompasses three municipalities in the very north of Sweden, just by the Arctic Circle, and has the potential to become a global hub for data traffic. This is mostly due to its reliable power infrastructure, the ample supply of low cost renewable hydroelectric energy and low air temperatures ideal for natural cooling.
The Alliance members are companies from the technology and construction sectors who combine their knowledge and experience to build world-class data centres.
“We are very proud to have been able to join the Node Pole Alliance”, said Alan Beresford, MD at EcoCooling. “The direct-air evaporative cooling systems we have developed are ideal for the climate in the Node Pole region and make the most of the resources available.”
Air temperatures so close to the Arctic Circle are not only cool enough to make refrigeration in data centres redundant – they can even be too cold for the IT equipment. Some systems shut down if the temperature drops below 14 degrees Celsius. EcoCooling has designed patented control systems and atemperation processes to keep the cooling air within a tightly controlled temperature band – typically 18 to 21 degrees Celsius.
By joining the Node Pole Alliance EcoCooling will work alongside some of the most innovative companies like Hydro66, Vattenfall, Facebook, KnC Miner and ABB.

As 200th Installation Announced, Direct-Air Evaporative Cooling Becomes Mainstream

EcoCooling, the leaders in direct-air evaporative cooling today revealed they have completed their 200th data centre cooling installation using the energy saving technology.

 

“Using CRECs (computer room evaporative coolers) instead of the conventional CRAC units (computer room air conditioning units) can save over 90 per cent of the energy needed to cool a data centre,” said EcoCooling managing and technical director Alan Beresford, “we are very pleased to announce Serve The World as the 200th data centre to adopt this solution at its 600kW Oslo facility in Norway.”

 

Data centre engineers are by nature very cautious and it has taken a number of years for the CREC cooling to be accepted as a safe and reliable alternative to expensive refrigeration-based CRAC cooling. Serve The World now joins a list of highly respected data centre operators able to operate with PUEs (power utilisation effectiveness) of 1.2 or less regardless of the level of occupancy in the data centre.

 

Other data centres which have grasped the power and cost saving EcoCooling CREC cooling technology include Insurance company Unum, UK telecoms companies BT and TalkTalk, public sector organisations Humberside police and Warwickshire County Council plus colocation specialist Capgemini, as well as Cambridge University and RNLI (the Royal Naval Lifeboat Institute)

 

Within the 200 installations there are data centres with power consumptions from 10kW to 1MW. For a 1MW installation the EcoCooling CREC solution would require only around 40kW of power compared to as much as 1000kW with conventional CRAC cooling. This saves the cost and infrastructure for 960 kW of power.

 

Aberdeen University Data Centre – cooled by EcoCooling CRECs has been awarded Data Centre Project of the Year in the BCS & Computing UK IT Industry Awards – covering the UK’s entire IT industry. Aberdeen beat off competition from Tesco, Capital One and the NHS.  A number of best practices including the deployment of EcoCooling CRECs has led to a PUE of less than 1.1.

 

EcoCooling’s direct-air cooled data centre projects are spread far and wide beyond the UK with installations also in New Zealand., Germany, Ireland and the latest Norway-based Serve the World.

 

Explaining how the CREC technology works, Beresford said, “in temperate climates there are up to 365 days every year when so-called ‘free cooling’ can be employed. On a fair proportion of these days it is simply enough to pass air from outside through the data centre servers and other active equipment at a suitable rate and no cooling of that external air is needed at all. On the remaining days, it is sufficient to use a very simple technique of water evaporation which takes heat out of the incoming air and cools it sufficiently to cool an entire data centre.”

 

“Concerns of data centre engineers about the use of fresh air in data centres have not materialised.  With over five years operational experience and research data now available from these 200 installations the EcoCooling CREC design principles and process controls have proven to provide a resilient and efficient cooling system. I think the list of major players that have fully researched the topic and have then implemented EcoCooling technology demonstrates that data centre engineers can now consider this power saving technology as being fully ‘of age’,” Beresford concluded.

 

New Cooling Solution Brings Major Savings To Telecoms And Server Rooms

For several years now Data Centres have been cutting the cost of cooling by 80 to 90 per cent thanks to direct-air evaporative cooling.

 

Market leader EcoCooling has now developed a smaller unit ideal for the telecoms room and small server rooms which have historically been some of the most expensive locations to cool due to the highly inefficient and often unsuitable refrigeration cooling units deployed.

 

Launching the new 15kW evaporative cooler, EcoCooling’s managing and technical director Alan Beresford explained, ‘small office-type air conditioners have been used to cool areas such as telecom rooms and small server rooms, but these are not really suited to cooling IT equipment and can be very inefficient. Refrigeration coolers naturally use a lot of energy and in-fact office type coolers simply aren’t designed to deal with the high levels of concentrated heat produced by modern servers, routers and switches.’

 

Often, to remove 15kW of heat from a server room the energy requirement to run the refrigeration coolers would amount to a further 15kW of electricity.

 

The new EcoCooling evaporative cooler requires a mere 400watts to remove 15kW of heat.  This can save over £10,000 per year in cooling costs.

 

With one leading University already looking to deploy 60 of these units – and save over 500kW of power the new product is set to be extremely popular!

Also, while refrigeration-based coolers whose efficiency gets far worse when they are partially-loaded, the new EcoCooling units are highly efficient at low loads.  5kW of cooling will require less than 50W of electricity.

 

The new 15kW cooler from EcoCooling requires no external condenser unlike conventional air conditioning units and is a self-contained compact unit at just 1.4m x 0.9m x 1.9m.  The units are also designed for ease and speed of maintenance and all maintenance is carried out inside the building.

 

The very simple installation method means the 15kW EcoCooling unit is significantly less expensive than conventional external units making the massive energy savings available to small server and telecoms rooms.
