The NEXTDC M2 facility contains two levels of data hall’s and two dedicated outside air pressurisation (OAP) air handling units (AHU) providing conditioned air to each hall operating independently for redundancy.
The Building BMS provides control and monitoring of the building HVAC services including the CRAC closed circuit evaporative coolers, data hall pressurisation AHU’s and loading dock CO control systems.
Systems using HLI interfaces are the indirect evaporative coolers, fan VSD’s, data hall pressurisation AHU’s, loading dock CO control systems and a third party HLI interface to the site wide CSMS by BACnet IP.
