STULZ offers the broadest range of cooling capacities for chilled water (CW) and direct expansion (DX) units on the market. With 21-730 kW of cooling, there is a CyberAir air conditioner (CRAC) or air handler (CRAH) for every mission-critical application.
Applications:
- Small IT rooms to large enterprise data centers
- Medical/Healthcare
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 the 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
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
- Microplate heat exchangers offer major improvements in heat transfer
- Optimized AWS/Free-cooling coils to closely match DX cooling capacities, increasing energy savings opportunities
- A 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 the load requirement
- Electronic expansion valves can be optimized to work over a wide range of conditions
- Made in the USA
