All you need in one place

New energy and performance standards require air conditioning systems with precise close control to achieve high reliability, better humidity and temperature control as well as part-load efficiency. These features are crucial for areas where close control units typically operate; i.e. in data centers, mobile phone network exchanges and server rooms, where cooling is business-critical.

Such cooling units need to operate reliably either continuously or intermittently, and provide cooling in both compressor and free cooling modes. The maintenance of a stable temperatures and humidity control are key design challenges in these applications, since they are used in environments where ambient temperatures often vary significantly during the day.

Danfoss micro channel heat exchangers (MCHE) let you take advantage of low temperature fluctuation to create cooling systems that safeguard these sensitive technologies. Our compressors provide you world-class efficiency ensuring lower running cost and reliable operation. All of these backed up by Danfoss’ excellent technical support from our expert teams.

    Low PUE in data center cooling saves energy and costs

    A British manufacturer have recently installed a scalable data center together with one of their customers which has achieved the impressive Power Usage Effectiveness rating (PUE) of 1.21.

    For security reasons we cannot reveal the name and the location of the data center since the information managed by the servers is in many cases very sensitive.
