Cooling specialists Airedale have launched the new DCS range, a family of air-cooled chillers specifically optimised for demanding data centre environments, featuring ground-breaking Enhanced Free Cooling technology.
With uptime and energy efficiency hard-wired into every facet of their design, the DCS range has evolved from decades of worldwide data centre experience. The range has been specifically designed by the Data Centre Solutions team, based at Airedale’s global headquarters in Leeds, UK, to deliver powerful, reliable and sustainable cooling in the most demanding of environments.
Utilising existing Airedale chiller platforms DeltaChill, TurboChill, and OptiChill, the DCS team has implemented multiple upgrades to meet the unique requirements of the data centre market. 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 to 32 degrees Celsius), 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 the Enhanced Free Cooling package, this range of high-efficiency chillers has the potential to offer 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 airflow, the Enhanced Free Cooling package is 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 per cent annual energy cost savings over traditional free cooling methods. The reduced requirement for less mechanical cooling, in turn, reduces the stress on components such as compressors, thus reducing maintenance requirements and increasing the longevity of the unit.
Over its full life cycle, the combination of reduced energy consumption and lower approach temperatures leads to improved PUEs, allowing data centre operators to meet their environmental targets.
Patrick Cotton, product manager for chillers at Airedale, said: “In modern high-capacity data centres, balancing performance with sustainability, without compromising, is a priority, as data centre operators work hard to reduce their carbon footprint whilst maintaining availability during a global surge in demand for data. Working closely with some of the world’s largest data centre operators, we have been able to design and deliver our DCS range of chiller products to meet worldwide efficiency targets, whilst delivering the future of data centre cooling.”
