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.

The focus on cutting energy consumption and reducing the carbon footprint has never been greater, but results are often achieved by compromising usability or efficiency. The Danfoss Heat Recovery Unit delivers strong environmental benefits as well as significant reductions on heating bills—all delivered with a short ROI.
Danfoss has upgraded its MCX15B and MCX20B controllers with the introduction of the MCX15B2 and MCX20B2 controllers. Both models combine best-in-class connectivity, security, and performance with improved compressor control logic for VZH inverter scroll compressors.
Danfoss has boosted the part load performance and the operating map of its leading VZH variable speed scroll compressor range. The third-generation of commercial inverter scrolls VZH retain the strengths of the previous version, with the addition of the Intermediate Discharge Valve (IDV) technology for enhanced seasonal efficiency, and a wider operating map.
