InterDC wants to be as green as possible. Last week we installed a new drycooler in our datacenter in Enschede. With this unit we are able to keep our data rooms cool without using any compressor or cool techniques. Just with plain water a pump and some fans! This way our cooling system is very efficient and has a low energy use. The only downside is that when the temperature outside is above 20 degrees Celsius we need to transfer to traditional cooling. Fortunately most of the year the temperature outside under this threshold.
