EC Fan Retrofit Kit
EC Fan Retrofit Kits significantly reduce the operating costs in your data center. Easy-to-install, variable speed EC Fan Retrofit kits replace belt drive DWDI blowers for clean, efficient upgrade to legacy mission critical air handlers.
- No changes required to the primary electric or piping
- Provides superior air distribution
- Built-in fan redundancy
- Easy installation
- Quiet operation (low vibration, no inverter whine)
- Low maintenance (no belts to adjust, no belt dust, no greasing)
- Made in the USA
Stulz Replacement CRAH
Direct Drop-In Replacement
Increase cooling capacity and achieve significant energy savings without redesigning your data center. STULZ Replacement CRAHs are high capacity, direct drop-in, chilled water units with modern EC fans. They replace inefficient legacy units with belt-driven fans and provide instant energy savings and improved performance.
- No modification to existing piping mains, primary electric, or floorstand
- STULZ V-Coil arrangement
- Energy saving advantages of up to 40%, simply by replacing the CRAH
- Additional energy savings of 50% and beyond can be achieved using advanced controls
- Increased air volume at maximum fan speed
- EC Fans operate at lower speeds, lower energy, even airflow
- EC Fans consume less energy, therefore higher net cooling capacity
- EC Fans provide optimized under-floor pressure and balanced airflow
- Fast ROI; qualifies for utility rebates
- Provides advanced communication and control capabilities
- Lowers maintenance costs
- Made in the USA
