Airedale chiller enhances data centre free-cooling

UK: Airedale’s new DCS air-cooled chillers are specifically optimised for data centres with the ability to deliver a higher percentage of free cooling over the course of a year.

Building on its existing DeltaChill, TurboChill and OptiChill chiller platforms, Airedale says it has implemented multiple upgrades into the DCS to meet the unique requirements of the data centre market. The range has been specifically designed by the Data Centre Solutions team, based at Airedale’s global headquarters in Leeds.

Enhanced controls functionality, such as compressor fast-start and optimised head pressure control, has been added along with hardware upgrades such as battery-free UPS and automatic transfer switches to conserve uptime. 

The chillers are also designed to operate at increased supply/return water temperatures (20/32ºC), in line with data centre trends and to maximise free cooling potential. 

Available with a range of compressor technologies and refrigerants, including low GWP option R1234ze, and featuring Airedale’s Enhanced Free Cooling package, this range of super-high efficiency chillers claims unparalleled energy savings and a much reduced carbon footprint.

With a complete redesign of the V-block condenser coils and the implementation of larger EC fans to maximise air flow, the Enhanced Free Cooling package is said to be able to deliver a higher percentage of full free cooling over the course of a year. 

The mechanical upgrades, coupled with the ability of the DCS chillers to operate at increased maximum supply/return water temperatures, can deliver up to 39% annual energy cost savings over traditional free cooling methods, says Airedale. 

The reduced requirement for less mechanical cooling in turn reduces the stress on components such as compressors, thus reducing maintenance requirements and increasing longevity of the unit. 

The DCS chiller range includes TurboChill DCS (200kW to 1830kW), DeltaChill DCS (110kW to 1100kW) and OptiChill DCS (1850kW). Enhanced Free Cooling is available on TurboChill DCS and DeltaChill DCS.
