- 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
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
