CyberAir 3 DX
CyberAir 3 DX
For more than 40 years, we have been designing and developing high-efficiency precision air conditioning systems for data centers. Years of technology accumulation and the combination of new development tools have led to the advent of CyberAir 3. CyberAir 3 is extremely flexible and allows system solutions to be tailored to the user's needs. The CyberAir 3 precision air conditioning system can meet the extremely demanding requirements of air conditioning usage and energy efficiency. Through 8 cooling modes, 7 sizes and a variety of equipment options to choose from, STULZ's professional engineers can create customized system solutions for your special needs.

All details about CyberAir 3 DX
Mission Energy: Precision air conditioning wholly reinvented
Five cooling system cool with two refrigerants
From a choice of five cooling systems, data center operators will find the optimum balance between investment, operating costs and energy efficient. In addition to water as the cooling medium, the STULZ CyberAir 3 DX can run with two different refrigerants: standard R407C and R410A refrigerants.
The CyberAir 3 is available in cooling capacities between 22.4-120.6 kW.
EC compressors for saving in partial load mode New panel system
CyberAir 3 AS/GS and GES units are available with EC compressors, so that cooling capacity is changed by speed regulation, depending on actual heat load. That means maximum efficiency for partial loads combined with rapid changes in cooling capacity over a wide range from 30% to 100%.
- Best efficiency in cooling capacity due to stepless compressor control
- Best electronic efficiency due to brushless and maintenancefree motor
- Best mechanical efficiency due to scroll compressor
Adaptive ventilation with EC technology
For the CyberAir 3 we went one step further, and entrusted ebm-papst with the task of developing a fiberglassreinforced EC fan in a special size for the CyberAir 3, precisely in line with our specifications. The electronically controlled EC fans react steplessly to changing output requirements and are especially economical in partial load mode. EC fans consume up to 30% less energy than conventional AC models！
Up to 60% more econimical with STULZ indirect Dynamic Free Cooling automatic air conditioning
Full hybird with Indirect Free Cooling
Indirect Dynamic Free Cooling combines compressor cooling and free cooling in four stages, and automatically searches for the most economical operating mode. In cool weather, the dynamic control system makes use of economical Indirect Free Cooling, which extracts all its cooling power from the outside air. Energy-intensive compressor cooling (DX) is only switched on when absolutely necessary.
Complete electronic control for Indirect Dynamic Free Cooling savings
With utmost sensitivity and precision, this system selects the most enerfy-saving mode, controls the speed of the EC fans in the air conditioning unit and those of the dry coolerm regulates the position of the control valves, reduces the electricity consumption of the pumps and ensures precise interior climate control. By incorporating standby units as well, Indirect Dynamic Free Cooling keeps all units, pumps and dry coolers in perfect balance in energy-saving partial load mode.
