Centrifugal Compressor Energy Efficiency Upgrade for a Battery Materials Manufacturer
Project Background
Energy consumption by centrifugal compressors constitutes a significant share of industrial operating costs. A battery materials manufacturer in Southwest China sought to replace high-energy-consuming compressors with SIND centrifugal compressors to achieve energy savings and demonstrate the potential for cost reductions in battery manufacturing applications.
Equipment Operation Comparison
Before: Legacy Centrifugal × 3
| Motor Power | 800 kW |
| Rated Current | 54 A |
| Actual Power | 752.6 kW |
Readings (Day 1):
Machine 2: 50.2A, Machine 3: 55.5A
Measured average current: 54.9A
Actual power draw: 752.6 kW
After: SIND Centrifugal × 1
| Motor Power | 450 kW |
| Rated Current | 793 A |
| Actual Power | 394.4 kW |
Readings (Day 2):
SIND current: 695A
Actual power draw: 394.4 kW
Energy Savings Calculation
Power Savings
752.6 kW – 394.4 kW = 358.2 kW
