The co-location facility is capable of hosting 1000s of computer systems, all with individual power supplies, storage systems, processors and other heat generating components.  To keep the temperature and humidity levels constant, a twin Hiross air conditioning system in installed. 

Air conditioning is such a vital part of the facility that two separate systems have been installed that operate independently, with each able to cool the entire facility.  Both units are also fed directly from the back up generator  ensuring they are always operational, even during a power outage.

The temperature within the computing facility is maintained at a constant 20^oc - ideal for computer equipment that needs to be kept cool to operate efficiently.  The system also modifies the humidity in the computer room; too little humidity causes static build-up, too much causes conductivity problems.  For uninterrupted operation both these factors must be carefully controlled.

The conditioned air is fed into the floor void creating a positive under-floor pressure.  Each cabinet has a vented floor tile which allows the air to flow through the cabinet.  In normal circumstances, the rack cabinet is kept closed, creating a virtual tube through which the cool air flows.  The fans in the roof of the cabinet further improve the airflow by drawing air upwards.  Heated air is then removed from the room via the return vents at roof level within the computer room and is recycled through the air conditioning process.
