Semi-Hybrid Product Range


At its heart Air2O Semi Hybrid IDEC technology utilizes a two stage evaporative cooling solution, in conjunction with either a chilled water coil for additional cooling or hot water coil for heating. In the first stage, outdoor air is passed through the heat rejector section of the unit, which houses an evaporative cooling system optimized to cool water.

This cooled water is then transferred to a high efficiency heat exchanger within the supply section of the unit, over which the primary supply air is passed, delivering the first stage of cooling with no added moisture – Indirect Evaporative Cooling. The air is further cooled as it passes the second cooling stage – Direct Evaporative Cooling, or the chilled water coil.


‘The combination of these two stages plus an additional chilled water coil delivers the highest performing evaporative cooling system in the world today.’

Air2O’s equally unique intelligent control system, ACSESS, automatically responds to external weather conditions, continuously adapting its cooling strategy to run only the most efficient cooling systems for the ambient condition of the moment. This means that the higher energy systems are only used when needed, ensuring consistent performance, high efficiency and significant energy savings.
