EC Fan Retrofit Kits for reduced OPEX
Easy-to-install, variable speed EC Fan Retrofit kits replace belt drive DWDI blowers for a clean, efficient upgrade to legacy data center air handlers. The STULZ CyberMod EC Fan Retrofit & Replacement Kit has distinct energy saving advantages over other similar retrofit kits on the market, which use variable frequency drive (VFD) motors.
Benefits
- 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
Features
- Extend the life, improve efficiency & reliability of existing systems
- 2 and 3 fan configurations available
- No changes required to the primary electric or piping
Replacement CRAH
Retrofit & Replacement
For More Information:
Replacement CRAH for Legacy Data Centers
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.

They replace inefficient legacy units with belt-driven fans and provide instant energy savings and improved performance. Increase cooling capacity and achieve significant energy savings without redesigning your data center.
STULZ Replacement CRAHs provide 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.
Benefits:
- No modification to existing piping mains, primary electric, or floorstand
- STULZ V-Coil arrangement
- Energy saving advantages of up to 40%, simply replacing the CRAH
- 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
- Additional energy savings of 50% and beyond can be achieved using advanced controls
- Provides advanced communication and control capabilities
- Increased air volume at maximum fan speed
- Lowers maintenance costs
- EC Fans operate at lower speeds, lower energy, even air flow
- Made in the USA
Features:
- State-of-the-art E2 Microprocessor with a range of BMS interface options
- No modification to existing piping mains, primary electric, or floorstand
- Increased flow rates at maximum fan speed • EC Fans produce less motor heat, therefore providing higher net cooling capacity
- EC Fans operate at lower speeds, lower energy, even air flow
- EC Fans provide optimized under-floor pressure and balanced air flow
- Fast ROI; qualifies for utility rebates
- Lowers maintenance costs
