With Direct Free Cooling, conditioned ambient air below 18°C is used to keep the data centre cool. This brings huge potential savings, but challenges as well. With this cooling method, a large volume of ambient air enters the rooms, so that extended temperature and humidity tolerances must be permitted. If the ambient temperature rises above 18°C, either an integrated DX system with compressors or a separate chiller assumes the task of cooling the data centre, depending on the air-conditioning solution that is installed.

Thanks to our many years of experience with precision air conditioning solutions, we have succeeded in optimising all components for Direct Free Cooling, ensuring compliance with the specifications for data centre temperature tolerances according to ASHRAE TC 9.9 – 2008.

In addition, the cooling unit and mixing and filtration box are available in various sizes, so they can be selected precisely to suit your requirements and to achieve optimum energy efficiency.
Advantages
High energy efficiency through the direct use of Free Cooling
Fold-away heat exchanger in the CyberAir AMD for additional energy efficiency
Additional savings opportunities in Mixed and DX mode, thanks to enlarged heat exchanger surfaces and low condensing temperature
Excellent system scalability – “Build as you grow!” No hydraulics (pipework, pumps, fittings)
Maximum reliability thanks to self-contained, simply constructed air-conditioning systems
Drastically lower energy consumption than all conventional systems
High-quality materials and perfectly harmonised components
Lower capital investment than with Indirect Free Cooling systems
