Flexible design enables more customisation
STULZ HAS UPGRADED the DX models of its proven CyberAir 3 DX series delivering even greater efficiency savings and increased cooling capacity.
Building on the success of the CyberAir 3 DX, STULZ has taken energy efficiency to the next level with the launch of the CyberAir 3PRO DX series. Offering exceptional Energy Efficiency Ratios (EER) and Airflow Efficiency Ratios (AER), this enhanced range of precision cooling units ensures maximum reliability for mission critical applications, as well as achieving signifi- cant savings in energy and costs.
Providing the energy-saving advantages of in- direct free cooling, the Stulz GES hybrid systems are available with outputs in excess of 100 kW.
These new developments offer all output levels – from 30 kW to 130 kW and the provision of cooling systems with tandem compressors – ca- pable of handling partial loads- potentially in- creasing further energy savings.
The range also includes units with integrated fans, available with standard ASD (Downflow) and ASU (Upflow) air conduction. By optimising the design, the units are now considerably more efficient than previous versions.
The key design benefits of the CyberAir 3PRO DX series include: higher cooling capacities with a minimum footprint, lower refrigerant require- ments, and high sensitive cooling capacity (SHR). In addition, the units also boast the largest pos- sible heat exchanger and filter surface areas for minimal pressure drops.
Flexibility is another significant advantage – the size, cooling capacity, air conduction and control system can be tailored to meet the pre- cise requirements of mission critical facilities.
In addition, as the supply air temperatures of the cooling systems lie within the recommended range of between 18 °C and 27 °C, they are fully ASHRAE-compliant.
The DX Series has a smaller footprint with higher cooling capacilities.
The CyberAir 3PRO DX range currently pro- vides five different cooling options, to help achieve the ideal balance between investment, operating costs and energy efficiency. Each de- sign is optimised to help ensure the highest lev- els of IT uptime in mission-critical environ- ments, through cost-effective thermal control.
