Spoiler alert: They are. More specifically, they can be. Using VSD compressors in mining is a smart idea – if they meet the tough demands of the industry.
Atlas Copco GA VSD+ compressors operate reliably in dusty, dirty, hot, and cold mining conditions. They also perform well at high altitudes. Compared to traditional fixed-speed air compressors, they offer outstanding reliability, energy efficiency, and productivity.
Fixed-speed vs VSD compressors in mining
Variable speed drive compressors are essential in modern operations as they deliver significant reductions in energy consumption.
Some believe VSD air compressors are more fragile because of their electrical components. Still, there are variable speed drive compressors that work well in demanding mining environments.
VSD air compressors suitable for mining offer many benefits over traditional fixed-speed air compressors. This is especially important as the mining industry moves towards a more sustainable production.
Here are three reasons why mining operations should switch to using robust VSD compressors, such as Atlas Copco’s GA VSD range:
- Reliability: Atlas Copco GA VSD compressors are reliable in rugged and dirty environments and at high altitudes. That’s because they have an IP54 rating on their inverter and an IP66 rating on their drivetrain. Both offer protection against dust and moisture.
- Energy efficiency: VSD technology can reduce energy consumption by double digits. That's because the built-in inverter allows the motor speed to match the demand for air. Fixed-speed compressor run at full speed all the time, even when air demand is lower. This requires a lot more (wasted) energy.
Compared to these fixed-speed models, Atlas Copco GA VSD units can save up to 60% in energy consumption. Their Automatic Restart After Voltage Failure (ARAVF) also keeps power going during outages while saving energy.
- High productivity: Mining-appropriate VSD compressors keep your production running smoothly and reliably, ensuring maximum productivity.
AIRCUBE, the containerized compressor room for mining
For mining customers, Atlas Copco also offers AIRCUBE. This modular containerized compressor room is the ideal solution for installation in tough remote locations.
With AIRCUBE, mining companies can select from a range of air equipment and options. Atlas Copco will assemble all these products in a 20 or 40-foot sea container with plug-and-play operation.
The AIRCUBE comes with a number of standard features, such as ventilation, internal power distribution, CE-certification and lighting.
All AIRCUBES can withstand temperatures from 0°C to 45°C as standard. High or low temperature versions (+50°C to -50°C) are available as an option.
Common questions related to VSD compressors in mining
Are variable speed drives (VSD) or fixed-speed compressors better for mining operations?
VSD compressors are more productive, reliable, and energy-efficient, making them the smart choice for mining operations. That is if they meet the requirements of the mining industry.
Can dusty and dirty environments cause VSD compressors to break?
Atlas Copco designed its GA VSD+ compressors to operate in harsh conditions. Unlike many other VSD compressors, their inverter has an IP54 rating to ensure the compressor functions effectively in dirty environments.
Can a VSD compressor work with a generator in mining without electrical issues?
Yes, Atlas Copco VSD compressors can work well with generators in mining. They adjust to changes in demand and save on energy costs.
So yes, VSD compressors in mining are a smart idea, provided they meet the specific demands of the industry. Those that do are changing the mining industry by providing better energy efficiency, reliability, and productivity.
