By installing ABB’s ACS 1000 medium voltage drive, productivity is expected to rise and energy savings are projected at $121,000 per year.
ABB installed its ACS 1000 variable speed drive on a 1,250 kW fixed‑speed pellet cooling fan at the Pefia Colorada iron‑mining operation in Mexico. The upgrade is projected to raise production by 151,000 tons per year and save about $121,000 annually in energy costs.
The drive also provides total process controllability, reduced motor noise and vibration, and lower service and maintenance expenses. Key technical data include a three‑level voltage‑source inverter, power range of 315 kW‑2 MW, output voltages up to 4.16 kV (optional up to 6.6 kV), and a maximum frequency of 66 Hz (optional 82.5 Hz).
| Inverter type | Three-level Voltage Source Inverter (VSI) |
|---|---|
| Power range | 315 kW - 2 MW |
| Output voltage | 2.3 kV, 3.3 kV, 4.0 kV, 4.16 kV (optional 6.0‑6.6 kV) |
| Maximum output frequency | 66 Hz (optional 82.5 Hz) |
| Type of motor | Induction motor |
The upgrade was projected to save about $121,000 per year in energy costs.
The ACS 1000 drive offers an availability of 99.9 percent.
The return on investment period is estimated at 34 months.
