Innovation and integration: bespoke
Power and cooling continue to dominate as a key topic for those involved in data centre design, build and operation. Here we highlight two recent installations that include cooling technology from Airedale.
CUSTODIAN DATA CENTRE, winner of the Data Centre Leaders Awards ‘Green’ category, designed its data centre with the highest environmental efficiencies in mind.
Partnership approach Working in direct partnership, Airedale designed and built an intelligent, energy efficient data centre cooling solution that significantly reduces the need for mechanical cooling and provides fresh air free cooling up to 80% of the year.
Airedale was selected for its ability to design and integrate control logic across multiple protocols, hardware and systems and for its pioneering free cooling technology and high specification chillers. With a system using direct fresh air in a data centre cooling environment, Airedale software is also critical in ensuring temperature set point and humidity are maintained. Airedale’s solution effectively controls the Air Handling Units (AHUs), Airedale free cooling chillers and legacy Building Management System (BMS).
Bespoke solution
The AHU dampers are controlled by Airedale’s bespoke control logic to maximise the effect of free cooling even when the outside temperature is above the supply air set point. When required, two external Airedale mechanical cooling chillers provide cold water to

coils in the AHUs. Chillers are programmed to operate with a dynamic chilled water temperature set point, ensuring water is provided at the optimum temperature required by the system and allowing free cooling whenever the ambient is below the return water temperature.
Airedale’s ACIS™ control system manages temperature and humidity in the data centre, with each control panel integrating with Custodian’s BMS to provide 24/7 monitoring. PUE figures below 1.15 are regularly achieved, meaning that for every 1kW of power used by equipment hosted in the data centre, 0.15kW of power is required to operate all related areas of infrastructure.
Scalable by design
The collaborative approach resulted in a scalable solution, with infrastructure and pipework installed at the start allowing further air handling and chiller units to be added with minimum disruption and without incurring unnecessary additional cost as data centre demand grows.
Performance from day one
Airedale’s dedicated commissioning and critical service solution ensures the system performed from day one and provides round- the-clock support and quarterly preventative maintenance to ensure optimum system performance.
