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.
Pressure switches and thermostats for refrigeration
The range of pressure switches and thermostats cover a lot of applications within refrigeration and air conditioning. The pressure switches and thermostats are in two categories: KP as standard and RT for heavy duty purposes. The switches can be delivered for fluorinated refrigerants as well as ammonia.
SGP is a series of sight glasses for high pressure applications (Max Working Pressure 52 bar/754 psig). SGP is available in versions optimized for refrigerants with mineral oil e.g. HCFC, and in versions optimized for non-flammable HFC refrigerants. SGP is available with flare, solder and socket connections, and with and without moisture indicators.
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.
Third-generation VZH scrolls bring further seasonal efficiency gainsMonday, May 27, 2019
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.
