The ability to offer such a wide range to customers is the embodiment of our philosophy, "Climate. Customized.". Size, design, air conduction, system or control: CyberAir 3PRO DX is a model of adaptability and the units can be precisely adapted to your individual requirements. In addition, a variety of options and equipment versions are available to achieve the optimum result.
Two designs for individual installation options
Specific air conduction systems
With two designs and air conduction systems specifically optimized for each unit, the CyberAir 3PRO DX ensures maximum flexibility for integration in your system.
Optimized unit design for maximum potential savings
The design of our units means that STULZ precision air conditioning units boast maximum EER values and the lowest AER (Airflow Efficiency Ratio) values, and therefore achieve air conduction with maximum efficiency. The AER describes the ratio of the fan power consumption to the airflow. ASR air conduction (fans integrated in the raised floor), in particular, hugely reduces fan power consumption by ensuring minimal turbulence and changes in airflow direction, for energy savings that you will notice straight away.
Optimum supply air conditions for reliability and maximum efficiency
To cool your data center as efficiently as possible without compromising on reliability, ASHRAE has published a recommendation for the air temperature at the server inlet. We have been developing air conditioning units for mission-critical applications – where even tiny malfunctions can have serious consequences – for decades now. Not only that, we have always focused on energy efficiency, and because of this, the supply air temperatures of our units lie within ASHRAE’s recommended range.
