Airedale supplies largest ever air cooled chillers

UK: Airedale by Modine has completed delivery of 21 of its largest ever 36-fan air cooled chillers, each measuring 22m long.

In addition to the 21 super-sized chillers, the order included two 16-fan free-cooling DeltaChill chillers, 72 AireWall units and 12 SmartCool ONE chilled water downflow units.

The order, for an undisclosed data centre operator, is believed to be one of the largest single, colocation orders taken by Airedale in their 50-year history. It also includes Airedale’s Cooling System Optimiser and an on-site building management system.

Working closely with the client, Airedale has designed a larger derivative of its DeltaChill R32 free-cooling chiller for the 30MW facility. 

Alongside the 36 high efficiency EC fans are 17 scroll compressors, selected due to their ability to deliver concurrent free cooling, maximising partial and full free-cooling availability. 

The 16-fan variants offer all the same efficiencies. Acoustic packages have been applied to all chillers to ensure stringent noise constraints are met on site. The units all feature integral harmonic filtration, to increase quality, reliability and energy efficiency, by reducing loss in electrical components and deliver indirect energy savings. 

One of the key differentiators for Airedale was the company’s ability to deliver a complete cooling solution, comprising not only high efficiency, free-cooling chillers, but also the computer room air handlers, controls packages and on-site project management and installation teams. This approach allows for the units to work as a system, increasing the opportunities for marginal gains and system efficiencies.

The cooling system optimiser and on-site BMS works to deliver a fully automated system at both product and system level. Likewise, the control system’s ability to recognise patterns and identify potential issues before they occur adds an extra layer of redundancy to an already robust operation.
