Datum's energy efficient adiabatic cooling solutions are designed to maximise energy efficiency using cost effective, state-of-the-art cooling technology.
Datum’s credentials for FRN1 as a green data centre are supported by ISO 14001:2015 for Environmental Management, ISO 50001 accreditation for Energy Management and the EU Code of Conduct for Data Centres. These build on Datum’s other accreditations, ISO 27001:2013 Information Management, ISO 9001 Quality accreditation, DCA Class 3 Fully Operational and PCI DSS compliance to continue to demonstrate Datum’s ability to deliver a secure and energy efficient environment for its clients’ critical IT infrastructures.
Datum’s accreditation to ISO 50001 is underpinned by an effective energy management system, a Plan-Do-Check-Act continual improvement framework and its energy efficient free cooling system.
Traditional approaches focus on chilled water CRAC units to distribute the supply air under a raised access floor and employing cold aisle containment. Whilst this is the prevalent legacy approach in the data centre market for low power densities, it is limited in energy efficiency and does not work as well at high power densities.
A better solution is the Free Cooling design that we employ. It uses a Flooded Airflow approach to deliver energy efficient and cost effective datacentres, significantly reducing running costs and carbon footprint both for ourselves and our Clients.
The flooded air supply together with separate ceiling return air path enables extremely energy efficient, predictable cooling for high and low densities, whilst removing the cooling plant and associated water service risks completely from the IT space.
The cooling system is designed to indirectly use ambient air to provide free cooling.
Complete separation of the supply and return air paths is achieved by isolating the hot and cold aisles.
Supply air is provided for the entire height of the room, removing the higher power required to pressurise a raised floor, whilst return air is ducted directly back to the cooling units via a ceiling plenum, removing the risk of any hotspots and ensuring a large cold air battery in the event of system failure or generator start.
Annualised energy use for our cooling design at full capacity achieves PUE of 1.25 at full load. Even at partial loads a PUE of 1.4 is achievable. The result is complete alignment of our energy efficiency goals with those of our clients a reduced carbon footprint and reduced cost.
