Reliable and energy-efficient solutions for CRAC /close control units
New energy and performance standards and low PUE targets in data centers, server rooms, and communication networks require Computer Room Air Conditioners (CRAC) with precise control to achieve high reliability, better humidity, and temperature settings as well as part-load efficiency. Ensure the cooling of your data server room will enable your business to perform at peak even with higher evaporating temperatures.
Precision air conditioning in data centers
Such cooling units need to operate reliably and provide cooling in both compressor and free cooling modes. The maintenance of stable temperatures and humidity is a key design challenge in these applications since they are used in environments where ambient temperatures often vary significantly during the day.
Danfoss microchannel heat exchangers (MCHE), scrolls with IDVs and inverter compressors, sensors, controllers, and electronic stepper motor valves let you adjust to temperature and load fluctuations to create cooling systems that safeguard these sensitive technologies while potentially reducing refrigerant charges. Our solutions include options for lower-GWP refrigerants. All of these backed up by Danfoss’s excellent technical support from our expert teams.
