DATA CENTRES COOLING


LIGHTER BYTES


DigiPlex’s Air-to-Air modular data centre uses indirect evaporative cooling technology to turn this energy-hungry building type into a model of minimal consumption. Mike Simpson reports


The evaporative cooling system operates in three modes to remove heat in the most energy-efficient manner

he DigiPlex Air-to-Air modular data centre has been developed to deliver high levels of cooling with exceptionally low power


consumption, while eliminating the risk of fire. Developed in partnership with air treatment specialist Munters and modular frame manufacturer Gardner DC Solutions, it combines indirect evaporative cooling technology with a hypoxic fire prevention system to provide an advanced, sustainable and efficient data centre solution. The Air-to-Air solution is assembled from three freestanding module types:


a white space, an electrical switchroom, and an air treatment pod (ATP). The white space module is designed to house the IT cabinets; it has a module area of 30m2


of net


usable space and incorporates a raised floor to provide a route for the chilled air to cool


the cabinet racks. The ATP provides up to 100kW of cooling to the white space. Because it is completely modular, the Air-


to-Air solution is easily scalable. Once the shell and basic infrastructure are in place, cooling units and white space modules can be procured and installed as the IT load increases. The minimum build is 100m2 based on three white space modules
