Julio Tome, product marketing manager for large generators at Atlas Copco, said: “Since we introduced the new QAS line in 2007, we always intended for the complete range to go up to 630kVA. Today, 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 and complementary to our forward-thinking approach.”
Like other models in the QAS series, the QAS 630 boasts a compact and sturdy design in a rugged galvanized enclosure, which reduces noise levels and ensures reliable operation. In addition, the spillage-free frame minimises environmental impact.
The standard fuel tank has a capacity of over 900 litres and can provide power for a full work shift at full load. An optional long-autonomy fuel tank can extend the running time up to 24 hours, depending on load requirements.
To meet the frequent moving and multi-drop needs of the rental business, the QAS 630 facilitates easy transportation, installation and storage with its small dimensions, balanced weight and strong base frame with forklift slots.
In keeping with the QAS development tradition, serviceability was a top priority in the product design and customer validation process. Large doors and removable service plates ensure superior accessibility and quick maintenance. Heavy duty filtration systems allow for long service intervals to further reduce downtime.
The QAS 630 (630kVA / 500kW at 50Hz prime power) comes in one emission variant, Stage II, and meets different regulatory requirements around the world including the EU.
The QAS 630 features the advanced but simple-to-operate Qc4003 controller, with a plug-and-play design that enables simple and fast configuration. Other features include the ability to remotely start and program the machine, as well as data analysis capability.
The controller is equipped with a Power Management System that enables the optimisation of fuel consumption and expands the lifetime of generators when they are working in parallel to form a mobile or independent power plant.
Additionally, Digital AVR is included as option. This new type of voltage controller allows customers to downsize the required generator in specific applications by enabling them to manage 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.
