Swedish manufacturer Atlas Copco recently unveiled the latest upgrade to its QAS generators range. Among other things, the new QAS5 models provide quieter operation, a 20% smaller footprint, reduced engine emissions, faster plug-and-play paralleling, enhanced fuel economy, 24h autonomy and lower total cost of ownership.

All models include Stage IIIA engines, a high-capacity fuel tank and integrated variable-speed drive (VSD) motor to power the cooling fan. Working in concert with an integrated VSD motor, these features result in an average 5% reduction in fuel consumption compared to the industry average for equivalent models.

“This year we are celebrating 30 years of leadership and innovation in the realm of mobile generators, and are proud to mark the occasion with the introduction of our QAS5 range,” Adrian Ridge, president of Atlas Copco’s Power and Flow division, said. “The fifth and latest generation of QAS gensets are designed from the outset to meet end-users’ evolving needs for sustainable productivity, increased operational flexibility and compliance with environmental and regulatory obligations.”

Given that excessive noise from portable energy equipment is becoming more undesirable in urban environments and industrial work areas, the QAS5 generators are 5–8dBA quieter on average than comparable generators.

Additionally, the compact QAS5 generators offer footprints up to 20% smaller than any comparable portable energy equipment on the market.

Owing to a newly developed Power Management System, the machines can be paralleled with each other in less than a minute, resulting in optimum power usage and high levels of on-site power redundancy. This is helpful to users with scalable power requirements.

All models in the QAS5 range are fitted with high-capacity fuel tanks capable of running for up to five working shifts, while a heavy-duty fuel-filtration system with water separator reduces service downtime.

Founded in 1873, Atlas Copco is a global leader in sustainable productivity solutions, specializing in the design and manufacture of industrial tools, air compressors and construction and assembly systems.
