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.

Danfoss variable speed technology
By using the Danfoss inverter compressor solutions, significant energy savings can be achieved compared to traditional on-off compressors or mechanically-modulated technologies.
NRV refrigeration check valves
NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.
ETS electric expansion valves
ETS is a series of electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions. ETS valves are compatible with electronic control solutions from Danfoss and other manufacturers.
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.
