Four new QAS 5 generators from Atlas Copco
New Stage V compliant portable units provide fast plug and play power from 250 to 660kVA
ATLAS Copco have introduced four fully EU Stage V compliant models to their flagship QAS 5 range of mobile diesel generators – the QAS 5 250, 325, 450 and 660.
As a result, Atlas Copco say operators can now reduce emissions and improve their carbon footprint, whilst also taking full advantage of the QAS 5 range’s compact size, quiet operation, enhanced fuel economy and low total cost of ownership, up to 660kVA power.
There are now nine generators in the range, providing fast ‘plug and play’ power from 80 to 200kVA on Stage 3A, and from 250 to 660kVA on Stage V.
‘The new generators are a welcome addition to the QAS 5 range and have been developed in response to customer demand for larger power capacity, but with a more sustainable operation that meets legislation,’ said Sergio Salvador, product marketing manager for small and medium-power generators at Atlas Copco.
The new QAS 5 generators have been designed to be quiet in operation, with noise levels as low as 85dBA. Atlas Copco say this is some 5–8 dBA quieter, on average, than comparable generators, depending on the application and load profile, and is due to advanced technologies including variable-speed drive (VSD) air cooling, silencers and a special isolated compartment for the power pack.
Featuring new, user-friendly touch-screen controllers, the ‘plug and play’ QAS 5 Stage V generators can be powered up within five seconds and can be paralleled with each other to form a mobile or independent power plant in just 55 seconds, thanks to an innovative Power Management System (PMS).
The PMS coupled with an integrated VSD to power the cooling fan is said to deliver excellent fuel efficiency, allowing operators to achieve up to a 5% reduction in fuel consumption along with resulting operational cost savings.
Uptime has been maximized on the QAS 5 machines thanks to a high-capacity fuel tank that can run for up to five working shifts, as well as a long service interval of 500 hours, which has been made possible by a dual‑stage air-filtration system.
In addition, the generators feature the optional FleetLink intelligent telematics system and have easy access to the engine, alternator, control panel and drain points, as well as a heavy-duty fuel-filtration system with water separator for minimal service downtime.
