CyberAir 3 – Maximum efficiency in data centre air conditioning

Data Centre Cooling Unit

When we introduced the CyberAir 2, we were the first manufacturer worldwide to present a precision air-conditioning system that cools data centres 60% more economically. Now, in keeping with the goals of our Mission Energy, our engineers in Hamburg have taken on the task of achieving even more potential savings for you with the CyberAir 3.

The CyberAir 3 precision air-conditioning system with DFC / DFC² conditions the air in data centres and equipment rooms with a heat load of over 20 kilowatts up to 90% more economically than conventional compressor cooling systems.

Along with the exacting requirements for data centre air conditioning, the need for exceptional ideas is also growing, such as how to regulate temperatures to within a degree at the lowest possible cost. To reach this goal, our engineers strive daily to enhance the energy efficiency of our precision air-conditioning solutions. The CyberAir 3 shows how serious we are: The result is a system with completely reworked air conduction, optimised in many details that work together in perfect harmony.

CyberAir 3 - Technology that pays for itself

  • EC fan with fibreglass-reinforced plastic wheel
    • Reduces the fan’s power consumption
    • Conveys the air more efficiently
  • EC compressor (for AS, GS and GES systems)
    • Best efficiency in cooling capacity due to stepless compressor control
    • Brushless and maintenance-free motor
  • High-efficiency rear panel (optional for DX and GE downflow systems)
    • Heat exchanger surface is used to the full
    • Reduced fan power consumption
  • Standby Management (for CW systems)
    • Keeps all A/C units in perfect balance in energy-saving partial load mode
    • Up to 70% lower fan power consumption
  • Better air conduction
    • More efficiency thanks to optimised air flow
    • Areas with hindrances to air flow are avoided
