IT / telecomms cooling systems
AireWall™ is a precision Computer Room Air Handling (CRAH) unit developed specifically for low-energy, high-density data centre applications. It removes the need for both pressurised raised floor systems and overhead cooling systems, with several options available ranging from 170 to 400kW cooling power.
AireWall™ comprises a filter and fan bank, a damper section and a chilled water heat exchanger. The damper section can be installed separately to maintain a clean data hall environment and individual sections can be removed for maintenance. AireWall’s integrated, intelligent controls mean it is self-regulating and highly adaptive to changing loads. The range has been designed to operate at low SFP to help achieve low installation PUE.
AireWall’s flexible and modular design lends itself to new-build data centres as well as upgrades, capacity expansions and equipment replacements in existing facilities. Maintenance costs are typically lower than other cooling solutions due to easy, direct access via the plant room, and the absence of computer room air conditioning (CRAC) units also frees up more space in the data centre for direct business use.
Airedale has developed the AireWall™ range to be utilised with Bluefin fans from Ziehl-Abegg. The Bluefin fans take inspiration from the fin of the humpback whale and have a bionic design, are airflow optimised and boast an efficiency increase of up to 15%. The corrugated blades ensure an optimised flow angle and reduced flow separation of the blade surface, for a diffuse sound output and significantly reduced noise. Quieter than more typical air cooling methods and available with a 4, 6 or 8 fan and 6, 8 or 10 row coil configurations the AireWall™ is a flexible and powerful solution for data centre cooling.
