Next generation data centre cooling Unparalleled efciency Available in ve footprints between 100kW and 440kW, with either wall or roof optimised connections, the AireFlow™ is a versatile free cooling and indirect adiabatic air handling unit (AHU), designed to make your data centre more productive and efcient. Reduced operating costs & carbon footprint By selecting the AireFlow™ you are investing in an AHU that will signicantly reduce your running costs and carbon footprint. The AireFlow™ is congured to optimise free-cooling potential even in high ambient temperatures. Using fresh air as the...

Based on London, UK ambient temperatures, systems can achieve 100% free-cooling year round (operating inside the ASHRAE recommended X axis: DRY BULB TEMPERATURE (°C) N + 1 fan configuration enhanced by smart control logic and EC fan technology, give the AireFlow™ built-in redundancy and excellent part load efficiencies

Resilient, powerful indirect adiabatic cooling For your data centre Wetted media versus spray systems – the benets Reduced risk of corrosion With the wetted media system, water is contained within the media and stainless steel drip tray itself, inherently resulting in a reduced risk of corrosion. Conversely, with a spray system, water coats all internal metal work in the adiabatic section, increasing the risk of corrosion damage. 37.5% less water storage required – 6m3 versus 9.6m3

Less water consumption The AireFlow™ consumes just 0.25m³ of water per hour whereas typically a spray system will use up to 0.40m³ of water per hour at peak UK ambient temperatures. Typical water consumption for a 1MW data centre in London A sterile environment The AireFlow™ unit is designed to ensure a sterile environment. Circulating water is constantly passed through a UV system to sterilise it and kill any bacteria and the self-cleaning adiabatic system automatically drains itself periodically. would be 600m³ per annum.* * Based on a datacentre with N+1 redundancy, operating with a 12K...

Brilliantly engineered For increased reliability High efciency air-toair aluminium plate heat exchanger A robust construction of aluminium with an epoxy coating ensures signicantly increased thermal conductivity, over plastic or composites, along with protecting against corrosion and high relative humidity on the ambient side. Designed for airows from 3m3/s up to 21m3/s, its sealed and alternate air paths prevent mixing, and gives a large heat exchange surface area for increased cooling capacity. Wetted media adiabatic system N+1 fan conguration for increased efciency and uptime The wetted...

Adaptive energy efcient operation Three distinctive operating modes Free Cooling – 0˚C – 15˚C Dry bulb temperature At low ambient temperatures the AireFlow™ can achieve 100% free cooling. The heat exchanger requires less ambient airow to deliver the cooling capacity, resulting in a lower power input. Adiabatic Free Cooling – 15˚C – 35˚C Dry bulb temperature (Max wet bulb approx. 24˚C) As the ambient temperature begins to increase, the heat exchanger requires more airow to deliver the required cooling, the ambient fans ramp up accordingly. Top up Operation (Concurrent Mechanical & Free...
