  • Provides power for a full work shift



By incorporating the compact frame of the QAS 500, the QAS 630 can generate 20 percent more power without needing a larger footprint, the company says.

The expanded QAS generator series now runs from 14 to 630 kVA.

"Since we introduced the new QAS line in 2007, we always intended for the complete range to go up to 630kVA," Atlas Copco product marketing manager Julio Tome says.

"Now we have achieved that milestone in the most innovative way, by fitting the new model into the frame of the existing QAS 500.

"The guiding design principle of the range was to be modular, compact and robust, which are important features for the rental sector."

Features of the QAS 630 include a rugged galvanised enclosure, which reduces noise levels and improves reliability, a spillage-free frame and forklift slots

The Atlas Copco QAS 630 generator is rated at 500kW at 50Hz prime power and comes in a Stage II emission variant.

"The standard fuel tank has a capacity of over 900 litres and can provide power for a full work shift at full load," Atlas Copco says. "An optional long-autonomy fuel tank can extend the running time up to 24 hours, depending on load requirements."

On the serviceability side, the QAS 630 has large doors and removable service plates for easier accessibility and quick maintenance. Service intervals have been lengthened through the use of heavy-duty filtration systems.

Features of the unit’s plug-and-play Qc4003 controller include the ability to remotely start and program the machine, as well as data analysis capability.

A Power Management System enables the optimisation of fuel consumption and expands the lifetime of the generators when they are working in parallel to form a mobile or independent power plant, Atlas Copco says.

A Digital AVR voltage controller is available as an option. This allows users to downsize the required generator in specific applications by managing the transient behaviour of the power.

"With smart control of the generator’s voltage, it’s possible to achieve lower fuel consumption, reduced maintenance cost and longer lifetimes," the company says.
