Applications

  • Small IT rooms to large enterprise data centers

  • Medical/Healthcare

CW Cooling

CRAH - Chilled Water (CW)

  • Largest capacity perimeter CW air handlers in the industry

  • Greater airflow than other solutions

  • Multiple EC Fan options (additional fans in same size cabinet)

  • All EC Fans mounted in the cabinet meet full performance without having to be dropped into the raised floor

  • Fewer units at higher capacity can significantly reduce capital cost and operating cost

  • 2 x CW valves standard on CFD-510 and larger units (option for 1 CW valve)

  • Dehumidification efficiently achieved through reduced air volume at maximum cooling

  • Standard and seismic floor stands available for all CW units

  • Filter plenums designed with increased surface area for filtration, lower pressure drop, and improved energy savings

  • Standard MERV 8 filters (optional up to MERV 14 filters)

  • 100% front access on all sizes

  • Made in the USA

DX Cooling

CRAC - Direct Expansion (DX)

  • DX systems provided with highly efficient and reliable low noise scroll compressors

  • Single or multi-stage compressor arrangement including tandem configurations

  • Micro plate heat exchangers offer major improvements in heat transfer

  • Optimized AWS/Free-cooling coils to closely match DX cooling capacities, increasing energy savings opportunities

  • Refrigeration-based dehumidification system effectively removes excess moisture

  • Hot gas reheat - provides reheat using recycled compressor heat

  • Snap acting / full floating hot gas bypass system provides cooling capacity modulation and evaporator coil freeze protection

  • Multiple stages of DX cooling to match load requirement

  • Electronic expansion valves can be optimized to work over a wide range of conditions

  • Made in the USA

STULZ provides a broad range of heat rejection options for STULZ DX Cooling

Heat Rejection Options
  • Dave Meadows, Applications Engineering Manager

    "Mission Critical applications require precise control of temperature and humidity 24/7/365.  The CyberAir series is the ideal, proven CRAC and CRAH to supply this control, cooling everything from small IT closets to the largest enterprise data centers in the world."

     

Controller

STULZ E2 Control and Monitoring

  • Precise control of temperature and humidity
  • Multiple I/O capabilities for all major components to optimize control for energy savings
  • Supports universal BMS interface for remote monitoring (address readable) and remote control (address writable)
  • Capable of networking controllers in a workgroup (pLAN) to work as one (no BMS required)
  • Pre-engineered controls for economizers and adiabatic cooling
