Custodian operates a revolutionary evaporative cooling system, completely negating the need for mechanical cooling, providing a positive impact for both the company’s efficiency and the wider environment.
For 95% of the year, the data centre utilises fresh air cooling, brought in from outside and filtered to clean room standards to eliminate contamination, passing into the data centre via a bank of multiple fans. In the event that British temperatures soar beyond a set threshold, the evaporative system comes online.
A reverse osmosis plant purifies water which the system then uses to produce a very fine mist. Within a large chamber, this moisture is used to raise the humidity of the slow moving air which passes through, decreasing its temperature. The evaporative system also acts as a room humidifier, and is supported by dual water mains, ensuring that it is resilient against mains failure. This approach is 2N resilient, with completely separate duplicate systems protecting against failure should one element be affected by outage or technical difficulty.
