Ultra low PUE, High rack energy, Fire proof - The DigiPlex Air to Air (A2A) Solution.
For 12 years, DigiPlex has been building and operating colocation data centres. Over this period ourcustomers’ ICT housing requirements and priorities have evolved and changed. Early customerrequirements for security, connectivity and resilience are now taken as data centre service givens. Today’sdata centre customer additionally require:
Low operating PUEs, delivering sustainable, efficient and economic operations.High power rack accommodation capability.Fast to market, flexible, factory produced quality construction.
The DigiPlex A2A modular solution delivers all of these contemporary needs plus more:Fire proof operations using hypoxic air technology.Sealed units preventing any external contamination or pollution.Size flexibility from 30m2 of white space to infinity – all column-free.

Specification Summary The DigiPlex Air to Air (A2A) Solution

At the heart of the DigiPlex A2A modular data centre is aclosed circuit ‘Air treatment pod’ (ATP). The ATP unitcapitalises on the cool, wet atmospheric conditions ofNorthern Europe and Scandinavia to deliver several layersof ‘free cooling’. By this means the ATP delivers importantsustainability and economic benefits over traditionalcooling technologies.
The A2A ATP essentially consists of two back to backcoupled air handling units (AHUs). One side of the coupledAHUs draws in outdoor air into the ATP, passing it over aspecially designed heat exchanger. This heat exchanger iswetted with a water irrigation system, thereby introducingpowerful adiabatic evaporative cooling effects. After passingthrough the heat exchanger, the outdoor air is re-expelledto atmosphere. The other side of the coupled AHUs drawsin air from the data centre white space hot aisle, passes thatover the cooled heat exchanger plus a load lopping DXcoil, and then back into the underfloor void of the datacentre cool aisles.
All of the cooling equipment is factory installed in the pre-packaged ATPs, which come complete with all necessarycontrols. The ATPs are configured in clusters of three units,thereby providing N+1 redundancy across three white spacemodules, each of 30m2 of net usable ICT space.
The DigiPlex A2A ATP replaces the need for data centreinternal CCU/ CRACUs and any external chillers or ADCsand associated pumps and water pipework circuits thataccompany more conventional water cooled systems.
The DigiPlex A2A ATP utilises a derivative of the Munters‘Oasis evaporative cooling system’ which is currentlydeployed on a large scale in the USA and Australia.
The entire white space volume of the DigiPlex A2A datacentre modules is sealed and positively pressurised. Thecontained internal atmosphere is de-oxified from a natural21% oxygen content level down to 15% - a level conduciveto healthy human working but entirely prohibitive of fireignition. The A2A modules therefore deliver completeprotection from external pollution and internal fire.
The DigiPlex A2A modular data centre delivers the datacentre requirements of today and tomorrow.
