Energy efficiency & reliability

Free Cooling

Two different Free Cooling methods are used for data center cooling, depending on how the outside air is used. If the outside air is conveyed directly inside the building, this is Direct Free Cooling. If the outside air does not penetrate the sensitive interior of the building, this is Indirect Free Cooling. Both methods offer advantages but entail certain challenges. We individually check which version best matches your needs, requirements, and intended use – and which solution provides you with the best value over the life of the system.

Sustainability with R513A refrigerant

Units with on/off compressors from the ASD/ASU and ALD/ALU model series of the CyberAir 3PRO DX range are available with R513A refrigerant.

As a drop-in refrigerant, R513A achieves similar energy efficiency and performance to R134a. In addition, R513A refrigerant belongs to the A1 safety classification, which means that it is neither toxic nor flammable, according to the American Society of Heating, Refrigerating and Air Conditioning Engineers’ (ASHRAE) guidelines. R513A refrigerant therefore ensures uncomplicated handling, making it ideally suited for data center applications.

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. 

Comprehensive control over all relevant factors is vital to achieve optimal performance and efficiency in a data center. STULZ contributes to this goal by providing the CFD (Computational Fluid Dynamics) service for data centers, using its unique fluid dynamics expertise at the product level to make the CFD simulation more accurate at the application level.

Delta T

The air-side difference in temperature between the air inlet and outlet of server cabinets and air conditioning systems is known as ΔT. To ensure optimum operation and the greatest possible savings on running costs, it is vital that the ΔT of the air conditioning units is adapted precisely and efficiently to the ΔT of your server cabinets.

Our dynamic control enables ΔT to be adapted to changing IT requirements, ensuring maximum energy efficiency during operation.

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, including our HVAC systems, lie within ASHRAE's recommended range.

In-house developed controller for regulating and monitoring the air conditioning system

Autonomuous controllers in every air conditioning unit for high redundancy and availability

Optional sequencing with standby functions enables the individual air conditioning modules of a group to be used to a greater or lesser extent with the utmost flexibility
