EC Fans are more efficient at partial load, where many data centers are running because they maintain efficiency throughout the entire speed and load range. They do not rely on incoming line voltage, which results in a more precise air flow. Lower motor temperatures result in a higher net cooling capacity, possibly reducing the number of air conditioners required.
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
The STULZ CyberMod EC Fan Retrofit Kit has distinct energy saving advantages over other similar retrofit kits on the market, which use variable frequency drive (VFD) motors.
