Hyper Efficiency

Using the latest in proven cooling and power distribution technologies, VIRTUS’ data centres are designed and run with optimal efficiencies that enable us to offer the lowest PUEs.

Our innovative data centre designs are a key way we manage to stay ahead of the market, keep costs lower and push standards forward. To keep our data centres as efficient as possible, we use a number of innovative design elements for greater efficiency while actually lowering costs: air flooded data halls utilising hot aisle containment and cooled using a variety of industry leading technologies. VIRTUS is committed to building and operating the most efficient and sustainable data centres as possible. To this extent, we ensure that all of our data centres are run on 100% renewable energy, sourced from only solar, wind or tidal power sources.

One of these technologies is called indirect evaporative air. It provides all the cooling we need but with a very low energy use. It works by drawing air from two sources: firstly outside air is drawn through the louvers on the side of the data centre and into the cooling unit; secondly, the hotter air from within the data hall is contained from the hot aisle of the IT equipment and enters the cooling unit. The temperature of the cooler outside air is used to cool the hotter air from the data hall via a heat exchanger before being returned into the data hall as cool supply air. Critically the air flow never mixes inside the cooling unit, ensuring the environment inside the data hall is kept free of outside contaminants.

This process works all year round, just using the temperature of the outside air. On the hotter days the cooling unit provides a water mist which uses a principle called adiabatic cooling to lower the temperature of the outside air entering the cooling unit, minimising any mechanical process. This reduces energy use, meaning a lower cost of ownership for us and our clients and a greener building for everyone.

To ensure we minimise the environmental footprint of the process and to reduce demands on the local water infrastructure, filtered groundwater is utilised via an on-site bore hole.
