Indirect Adiabatic Cooling for Data Centres

ITE Projects Ltd has partnered with Air@Work from the Netherlands to supply and install indirect adiabatic cooling systems for data centres in the UK.

The Air@Work system operates with a unique heat exchanger ‘StatiqCooler’, the internal passages have a hygroscopic (water-attracting) layer where evaporation and heat transfer takes place directly at the interface. This process is extremely efficient and will avoid the need for any additional mechanical cooling.


This cooling system uses energy efficient EC fans, ambient outdoor air and softened water. That’s all. This compressor-less system results in savings of up to 90% on your conventional mechanical cooling system energy costs!

The system operates most effectively when the data centre racks are arranged with hot aisle containment. Warm air (primary air) from the data centre racks is circulated through air passages in the heat exchanger ‘StatiqCooler’. The hygroscopic layer on the outside of the primary air side is kept moist, a second air stream (process air) flows in the opposite direction. This second air stream evaporates the moisture from the hygroscopic layer. Through this evaporation process the primary air is cooled. The humidified process air is then discharged to atmosphere. The cooled primary air is then circulated back to the rack cold aisle.

Key points

Sustainable: Most data centres have a large CO2 footprint, with traditional cooling systems being a major contributor. Our system has been developed as a truly ‘green’ air conditioning system, it cools with outdoor air and water and avoids the use of environmentally harmful HFCs used as a refrigerant in most compressor based air conditioners.

Reliable: Our system has very few moving parts to fail. The only parts that require any maintenance are the fans and valves and a small pump for the water supply.

Installation: Please call Air@Work today to arrange for a no obligation consultation on the feasibility of installing this latest efficient indirect adiabatic cooling systems in your new build or to replace your conventional mechanical data centre air conditioning system.
