Atlas Copco introduce the QAC1350

Atlas Copco QAC1350 generator

Environmentally friendly Stage V compliant TwinPower large back-up generator cuts total cost of ownership

ATLAS Copco have added a Stage V compliant model to their QAC series of containerized generators – the QAC1350.

The generator’s versatile TwinPower concept allows operators to cut fuel consumption while enhancing performance and complying with environmental regulation. Said to be more powerful, quieter and easier to transport than other units of the same power size, the generator suits a range of applications, including quarrying and mining.

Instead of one large engine, TwinPower technology leverages two smaller engines housed inside a containerized unit to achieve high power density with low fuel consumption, thereby reducing the total cost of ownership.


The new TwinPower delivers up to 1,350kVA as prime power. When used with a variable load, the QAC1350 consumes up to 40% less fuel than solutions with one large engine due to fewer mechanical losses. Compliant with the European Stage V regulations, the generator provides an environmentally friendly way to power operations, with nitrogen oxide (NOx) emissions reduced by up to 80%.

‘The TwinPower concept is the future of containerized generator sets, as it allows operators to reduce opex and capex while optimizing uptime,’ commented Sergio Salvador, Atlas Copco’s divisional product marketing manager for generators. ‘Crucially, the QAC1350 is also Stage V compliant, which makes it an environmentally friendly alternative to old single-engine technology.’

Measuring just 20ft in length, the QAC1350’s compact design and lighter structure make it easy to transport, and the generator is ready for operation as soon as it arrives on site, with optional power locks for fast connection.

The QAC1350 is equipped with a centralized control and monitoring system featuring Qc4004 digital controllers, making the system easy to configure and use. The intuitive touchscreen allows the operator to quickly review critical data and switch between the fuel optimizer, redundancy and split operation modes to prolong service intervals and minimize fuel consumption.

Depending on the application, the generator can run as a standalone unit or in parallel with the mains, providing operators with flexible access to power. Designed to provide the best possible uptime, the QAC1350 can be serviced in less than two hours, with a maintenance interval of 500 hours. Moreover, the innovative TwinPower construction means that it is also possible to use 50% of the unit’s total capacity during maintenance to avoid any downtime.
