The challenge

Custodian Data Centre, winner of the Data Centre Leaders Awards ‘Green’ category, designed its data centre with the highest environmental efficiencies Custodian Data Centre case studyin 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).
