Direct Free Cooling

 

Two designs for individual installation options

ASD and ASU versions

The design with integrated fans is available with standard ASD (Downflow) and ASU (Upflow) air conduction. Through further development and by optimizing the design, the units are now considerably more efficient than the previous version. This can be witnessed in the noticeably higher Energy Efficiency Ratio (EER) and lower Airflow Efficiency Ratio (AER).

ASR version

The ASR (Raised Floor) series promises even higher energy savings than units with fans on the raised floor. This model is equipped with an external fan box, and air conduction is specific to the unit. The fan box is installed under the unit, in the raised floor.

 

The resulting additional space in the air conditioning unit can be used for larger heat exchangers, resulting in a noticeably higher cooling capacity for the footprint. What’s more, positioning the fans in the raised floor means less turbulence and fewer changes in airflow direction. The result is ideal air conduction and therefore massively reduced fan power consumption (AER).

 

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

 

  • ASU Upflow

  • ASU Downflow

  • ASR front/back/down

  • ASR Front

The best result with the right 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.

Precise control

 

Our dynamic control allows an adaptation to important IT requirements such as the precise and effective adjustment of the air-side temperature difference (Delta-T) of cooling units to the Delta-T of the server racks. 

 

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.
