Atlas Copco’s new fuel-efficient mobile generators are Stage V compliant

Posted: Thursday 18th June 2020

Atlas Copco has introduced four new models to its flagship QAS 5 range of mobile diesel generators, which are fully EU Stage V compliant - QAS 5 250, 325, 450 and 660. Operators can now reduce emissions and improve their carbon footprint, while 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 660 kVA power.

These advanced generators are ideal for use in construction, events and utility applications, helping companies improve their fleet utilisation and return on investment.

“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,” says Sergio Salvador, Product Marketing Manager – Small & Medium Power Generators at Atlas Copco. “The QAS 5 generators are proven as reliable in demanding industrial environments and are enabling customers to improve plant performance.”

Events and industrial sites in urban environments are increasingly demanding quieter portable energy equipment and so the QAS 5 generators are designed to be especially silent in operation, with noise levels as low as 85 dBA. This is on average 5-8 dBA quieter than comparable generators depending on the application and load profile. This quiet performance is thanks to advanced technologies including variable speed drive (VSD) air cooling, silencers and a special isolated compartment for the power pack.

Space is a premium on any site, and the QAS 5 models are compact, with a 20 per cent smaller footprint than alternative generators in its class. As such, they are easy to transport and position on-site. They are also built with rental applications in mind and have exceptional portability with a sturdy frame and integrated forklift slots that can bear four times the weight of the unit without any deformation.

The generators are plug and play and can be powered up extremely quickly, within five seconds. Operators simply connect the generators for electrical power and the gensets are equipped with up to eight sockets, a terminal board and optional power locks to give users access to a safe, fast and flexible energy supply.

Furthermore, the QAS 5 generators can be paralleled with each other to form a mobile or independent power plant in just 55 seconds, which is a key advantage for operators with scalable power requirements. This allows for optimum power usage and high levels of on-site power redundancy.

The fast paralleling is down to an innovative Power Management System (PMS), which helps operators to efficiently manage the generators by starting and stopping the units when the load increases or decreases. The load on each generator remains at a level that optimises fuel consumption. The PMS eliminates the need for generators to run with low load levels, which can cause engine damage and shorten the life expectancy of the equipment. The QAS 5 Stage V models include new user-friendly touch screen controllers: Qc4004 + Qd070.

The PMS coupled with an integrated VDS to power the cooling fan deliver excellent fuel efficiency enabling operators to achieve up to a five per cent reduction in fuel consumption and saving in operational costs.

Uptime is maximised thanks to a high capacity fuel tank that can run for up to five working shifts, and a long service interval of 500 hours, made possible by a dual stage air filtration system which extends engine lifetime. Furthermore, this well-designed generator has an easily accessible engine, alternator, control panel and drain points and features a heavy-duty fuel filtration system with water separator for minimal service downtime.

The advanced generators also feature optional FleetLink intelligent telematics system, which enables users to monitor and optimises their machine fleet efficiently and conveniently see the location and performance of their equipment worldwide.
