Details for CyberAir CW and DX

A Megawatt of Cooling Capacity

Highest Capacity CRAH in the Data Center Industry

The CyberAir CFD-1080 is the largest perimeter CRAH in the data center industry, offering up to 96,000 CFM/987 CFM/ft2 of air handling capability.  The CFD-1080 comfortably maximizes the cooling capacity per square foot, while allowing for ease of rigging and modularity. 

Ideal Applications

  • Hyperscale Data Centers
  • Colocation Data Centers
  • Cloud ISP
  • Enterprise Data Centers

Modular Deployment

The CyberAir 1080 data center CRAH is uniquely designed for modular deployment, with six separate sections (two fan, two coil, and two return filter plenum sections) delivered. Once fully assembled, the 1080 stands an impressive 13 feet tall.  The modular CRAH unit design allows for ease of rigging, solving one of the major challenges for data center infrastructure equipment deployment. 

  • Easier to handle & maneuver smaller sections
  • Added system redundancy
  • Split sections for access limitation

Features and Benefits

  • State-of-the-art Microprocessor with a range of BMS interface options
  • Dual 2-way modulating CW valves (600 WOG rated)
  • Multiple EC Fan configuration options
  • Dual Cooling Coil Circuits for added redundancy
  • Fewer units at higher capacity for reduced capital and operating costs
  • Dehumidification efficiently achieved through reduced air volume at maximum cooling
  • Seismic and non-seismic rated floor stands
  • 1" thick, hinged access panels6-piece unit construction for ease of transport and installation
STULZ E² Control and Monitoring

STULZ E² Controller ties everything together

  • Designed specifically for precision control of mission critical environments

  • Supports universal BMS interface for remote monitoring (address readable) and remote control (address writable)
  • Capable of network controllers in a workgroup (pLAN) to work as one (no BMS required)
  • Pre-engineered controls for economizers and adiabatic cooling

Benefits

  • Backlit LCD alphanumeric display for visual indication
  • Operated via 6-key menus, in five different modes
  • Unit functions for cooling, heating, humidifying and dehumidifying
  • Three levels of restricted entry into the configuration
  • Sensor inputs control inputs/outputs
  • Additional I/O sensors and alarms
  • Optionals UPS backup module 
  • Independent EC Fan and cooling control (CW valve or DX)
  • Cooling control sequence: return air temperature, humidity, supply air temperature, dew point
  • Fan control sequence: BMS, local/static pressure, and temperature based (supply or return air)
