Applications & Use Cases

Military

MGS project pictures

Mobile hospitals and supply units heavily rely on generators such as our QAS 250 generator. A stable power source can make all the difference, and with marine grade protection and high overload capacity, this generator is always reliable.

Mining

These light pneumatic rock drills have been designed especially for the dimension stone industry, drilling holes of 27-41 mm.

In mining fields, diesel has a lower volatility rate than gasoline, making it a safer alternative to gasoline. Our QAS diesel generators from 250 to 700 kVA are always the number one option when working with mining materials such as coal, iron, or precious metals since it’s portable and can be used in remote areas with extreme conditions.

Utilities

QEC 1250 in a power management system (PMS)

In a time of power outages or when a power grid connection is compromised, diesel generators may be used by residential, commercial, and municipal areas. Whenever you need extra power, Atlas Copco's  generator can provide it, so life can continue on as normal.
